Why Re-run Drill Bits Can Be a Good Fit for Some Projects

Re-run drill bits are a crucial tool in the drilling industry. They are designed to be used multiple times and can save drillers a significant amount of money. Essentially, re-run drill bits are drill bits that have been used before and have been reconditioned to be as good as new. This means any damage or wear and tear that has occurred while drilling has been repaired, and the drill bit has been sharpened to maintain its performance. The process of reconditioning involves cleaning, inspecting, repairing, and sharpening the drill bit to ensure it meets industry standards. Re-run drill bits provide an eco-friendly option for drilling companies as they reduce waste and are an economically viable alternative to purchasing new drill bits.

Choosing the right drill bit for a project

It is important to choose the right drilling bit for a project, whether that is going to be re-run or new. The type of bit selected can significantly influence the success of the project and the time and resources required to complete the job. A poor quality or inappropriate drill bit can have a negative impact on the overall project’s results, leading to lost time, increased costs, and reduced success rates. Choosing the right bit can not only save time and money but also lead to more efficient results.

Advantages of re-run drill bits


Re-run drill bits are a budget-friendly option for companies looking to reduce their drilling costs. These bits are made from high-quality materials and are carefully inspected and refurbished to ensure that they are in excellent condition. This means that they offer the same level of performance as new drill bits without the higher price tag. Overall, re-run drill bits are an effective way for companies to save money without compromising on quality.


Re-run drill bits are durable pieces of equipment that can help drilling companies save significant amounts of money in the long run. As their name suggests, these bits are designed to be used multiple times, which means they can withstand the wear and tear of repeated drilling operations. Re-run bits are particularly useful for companies that frequently drill in the same type of formation or use a similar drilling technique. By investing in these high-quality bits, companies can reduce their overall drilling costs and improve their bottom line over time. 


Re-run drill bits are a step towards eco-friendliness in the drilling industry. These drill bits are used and have been refurbished for further use instead of being thrown away. They are designed to be durable, and with a little bit of reconditioning, they can perform just as well as a brand-new drill bit. By using re-run drill bits, drilling companies can significantly reduce waste and save money at the same time. Not only is this environmentally responsible, but it also makes business sense, as purchasing new drill bits can be expensive. With re-run drill bits, both drilling companies and the environment benefit.

Types of projects where re-run drill bits are a good fit

Re-run in-ground drilling bits are an excellent solution for a variety of drilling projects where budget constraints are a concern. These drill bits have a proven track record of performing well while maintaining maximum efficiency with minimal wear.

Water Well Drilling: What Bit Type Do I Need?

If you’re familiar with drilling at all, you know it’s all about the geology. It’s no different when drilling for water wells. Rock formation type, depth of the overburden, bedrock and the aquifer all play a role in how you determine the method of drilling and which equipment and drill bits you need. You might need roller cone bits, step drag bits, claw bits, chevron bits or PDC bits for water well drilling, but it’s dependent on the application. 


If you already know what type of bit you need, contact our team to make an order. O-K Bit is the world’s largest supplier of rerun bits, and we’re happy to provide you with whichever bits you’re looking for. 


Types of Water Wells

While you are probably interested in information about how water wells are drilled and what bits you may need, it’s important to note that drilled wells are not the only type of water wells. 


There are three primary types of water wells: drilled wells, dug wells and driven wells. Each has its own unique characteristics. 


  • Drilled Wells – Drilled water wells utilize a drilling rig and drill bits to bore into the earth. The bit rotates clockwise to create the borehole. As the bit breaks up the soil and rock beneath, the wells are drilled deep into the ground (often between 100 and 500 feet). 
  • Dug Wells – Dug wells are water wells that are created by digging a hole in the ground and lining the walls of the hole with brick, tile or stone. The hole is drilled to a level below the water table so that the water comes into the hole and can be bailed out. 
  • Driven Wells – These wells are made by driving pipe into the ground. Driven wells are relatively shallow (30 to 50 feet deep) and, therefore, they draw in water that is in aquifers close to the surface.  


All three types of wells penetrate below the water table into the aquifer below (although to different depths). The water from the aquifer is then pumped or bailed out through the well. However, driven wells and dug wells are more likely to be contaminated because they draw water from shallower depths which are more likely to have bacteria or contamination.  


How are water wells drilled?

Drilling water wells is a process that involves many steps. The lengthy process is valuable though because, if done correctly, a water well can provide water for a hundred years or longer. The process also helps drillers ensure they are equipped with the right tools and drill bits for successfully drilling the well. 

Steps for drilling a water well: 

  • Identify the desired location – Before beginning the process, it’s important to identify the well’s location and ensure an adequate supply of groundwater. If there is not an adequate water supply or the correct directional flow of water, you may need to select a different site. 
  • Evaluate the site of the well – evaluating the site is an important step for determining the desired depth of the well, understanding the rock formations present and selecting the equipment needed for the well. This includes choosing the correct drill bits for your water well drilling site. 
  • Drilling the well – drilling the well will involve setting up the drilling rig, drilling the borehole and installing the casing and screen. 
  • Pumping and evaluating – after the drilling, the pumped yield of the well will be evaluated and then developed. For most wells, there will be fine materials (minerals and sediment) that need to be removed so the water more effectively moves into the well.
  • Testing and disinfecting – The water will then be tested for quantity and quality. The well will be disinfected. After the water well is successfully drilled, it will be capped (for sanitary protection) until it can be connected to the customer’s system. 


Bits Used for Water Well Drilling 

A wide variety of drill bits are used for water well drilling. The rock formations of the drilling site will determine which bits are needed, but the O-K Bit team is equipped with whichever water well drill bits you need. 


The following bits are commonly used for water well drilling: 

  • Step Drag Bits 
  • Roller Cone Bits 
  • PDC Bits 
  • Claw Bits 
  • Reamer Bits 

Step Drag Bits 

Step drag bits are commonly used for drilling pilot holes. They are useful in this application because their cuttings are easiest to log and they are able to drill quickly. They are durable and hard, which means they have the longevity that many other bit types lack. Step bits are also used in sand, clay and other medium-hard rock formations throughout the drilling process. You should avoid using step bits in hard or coarse gravel rock formations because they will not be able to shear effectively. 

Roller Cone Bits 

Roller cone bits are identifiable by their rolling cone inserts. These cutting structures are useful for drilling through tough soil and rock. The tungsten carbide inserts are durable and self-cleaning, so as they crush and chip hard rock formations they remain productive. These bits are used at lower penetration rates, but they are especially effective at breaking up hard rock. 

PDC Bits (Polycrystalline Diamond Compact Bits) 

You may use a PDC bit for a water well drilling application if you hope to drill very precisely in soft to medium rock formations. These bits utilize a synthetic diamond compound on the cutters to create a highly durable and productive cutting structure on the bit. PDC bits are able to achieve high penetration rates while in use. 

Claw Bits

If your water well drilling site has a high volume of clay, a claw bit may be useful as you drill your water well. A claw bit is designed to use its uniquely shaped fingers to dig into and loosen hard clay that otherwise would be difficult to bore through. These bits are highly durable and the cutting structures (the fingers) can be replaced when worn. 

Reamer Bits 

Finally, reamer bits are often used in water well drilling to widen the borehole and keep the hole straight. The cutting surfaces of these bits are attached below drill pipe which then aids in keeping the hole straight and prevents bits from becoming gummed up with clay. Most commonly, reamer bits are used in sandy soils or clay formations. 

Well Drilling Methods

There are a wide variety of well drilling methods and techniques. The best approach will likely depend on the unique conditions of your drilling site. A few of these methods are: 

  • Down the Hole Drilling 
  • Air Rotary Drilling 
  • Bucket Auger Drilling 
  • Cable Tool Drilling 
  • Reverse Circulation Drilling 
  • Mud Rotary Drilling 

Regardless of the method or location of your water well drilling, O-K Bit is here to help you select the best new and rerun bits for the job. Contact our team today to order the supplies you need for water well drilling.

Matrix Body PDC Bits vs. Steel Body PDC Bits

If you have worked in drilling for any amount of time, you’ve probably heard about PDC bits. PDC stands for “polycrystalline diamond compact,” which describes the material compound that makes up these bits’ cutting surface. Both Matrix Body PDC and Steel Body PDC are made with this compound. 

These bits go by many names. They are commonly called: 

  • PDC Bits 
  • Polycrystalline diamond compact bits 
  • Composite chip tooth bits 
  • Polycrystalline diamond cutting block bits 

PDC bits are often used for oil drilling – but are popular in other industries as well. They were created in 1976 and are just as popular now as roller-cone bits (the kind of bit that has rotating parts). While PDC bits have a long history of success, they continue to evolve and constantly improve through new and innovative cutting angles, arrangements, and materials. These bits are very efficient as they work to shear away rock formations rather than crushing them. Each year, new advances in technology improve the efficacy of PDC bits and improve drilling speed. 

These bits are known as the “nose-to-the-grindstone” bits of the drilling industry – they get the job done and can be highly effective for a wide range of services and formation types—no moving parts to get jammed up, no fuss, just effective drilling for all your needs. 

You’ve come to the right place if you need new or rerun, refurbished PDC bits. O-K bit is the world’s largest supplier of rerun bits. We’d love to equip you with the PDC bits you need. 

If you want to learn more about Matrix Body PDC Bits and Steel Body, keep reading! 

What Are PDC Bits? 

There are two primary styles of PDC drill bits – matrix body PDC bits and steel body PDC bits. Both are similarly shaped round bits with four to eight cutting structures, or blades, that fan out from the middle. Each blade is then topped with between ten and thirty cutters. The bits have water channels dispersed for cooling, and there is a nozzle at the apex of the bit. If you’re trying to imagine this bit, it looks a bit like the crown a king might wear. 


PDC bits are used for oil and gas drilling, geothermal drilling, water well drilling, construction drilling, mining and horizontal directional drilling. O-K Bit can supply the PDC bits for your drilling projects; please contact us to place an order

The Science Behind PDC Bits 

You may have learned in school that diamond is the hardest material known to man. It is! And it is perfect for cutting through other materials like rock formations for drilling. 

PDC bits utilize tiny, inexpensive, man-made diamonds in their cutting structures. The process of creating the diamonds on these bits is complicated. Simplified, here is the process for creating diamond drill bits: 

  • The tiny synthetic diamonds are made 
  • The diamonds are then aggregated into large masses of crystals 
  • The crystals are then shaped into diamond tables 
  • Diamond tables are then bonded to metal, typically tungsten carbide, and a metallic binder 
  • This becomes the cutter part of the bit – there are many cutters on each blade of the bit
  • The cutters are then attached to the blades, which are attached to the body of the bit  

Together, the cutters and blades on the tip of the PDC bit are used to cut through rock formations of all kinds. 

Synthetic Diamonds in Drill Bits 

As you can see, synthetic diamonds are the key material for PDC bits. In manufacturing these bits, ultra-small grains of diamond (also called diamond grit) are created. This grit is very durable but becomes less stable at a molecular level when it heats up. So, your PDC bit is more likely to fail if not adequately cooled when in use. 

Regardless, synthetic diamonds are incredibly wear-resistant; they are the ideal material for longevity and durability. The metal type changes if you choose a matrix or steel body bit – but the diamond is critical.  PDC bits can have a long lifespan as long as they are adequately cooled. 

Matrix Body PDC Bits 

Matrix body bits are one of the most popular PDC bit types. They are made of a composite material that is both hard and brittle. The material is made of tungsten carbide grains metallically bonded with a softer, tougher metallic binder. While Matrix body bits are not as strong against impacts, they have much better abrasion resistance than steel body PDC bits.

Matrix body bits are created by using a mold heated in a furnace. The mold is filled with the metal composite in a solid form, heated to melt, cooled, and then assembled with the cutters. 

Uses of Matrix Body PDC Bits

Matrix body PDC bits are primarily used for these applications: 

  • Soft to medium-hard formations 
  • High volume 
  • High sand 
  • Applications where the same bit will need to be used for several bit runs 

Steel Body PDC Bits 

Steel body PDC bits are another of the most common PDC bit types. These bits are the opposite of a matrix bit in composition. They are made from steel instead of the metal composite used for matrix body PDC bits. They are excellent at impact resistance but are more likely to be compromised by erosion. 

Steel PDC bits use the cutting action of the bit to break up the rock it is drilling into. They are typically very stable and can drill at high speeds. 

These bits are made from steel bars. The bars are machined with metallic mills and lathes to make the bit body, and then the cutting teeth and post are welded to it. Steel PDC bits are more easily formed into complex shapes and designs. Creating intricate designs allows for a greater variety of cutting faces and features. Variations in cutting features can be helpful when drilling in unique rock formations. 

Uses of Steel Body PDC Bits 

Steel body PDC bits are useful in applications that include: 

  • Drilling in shale formations 
  • Soft limestone sites 
  • Fast drilling in the stratum 
  • Natural gas drilling 
  • Deep wells 
  • Abrasive formations
