12 best industrial drill bits
Industrial drill bits are cutting tools designed for use in various drilling applications, ranging from metalworking to woodworking and construction. These drill bits are engineered to withstand heavy-duty usage and are made from high-quality materials to ensure durability and precision. Here are some key features and considerations regarding industrial drill bits:
Material Composition:
- Industrial drill bits are often made from high-speed steel (HSS), cobalt steel, or carbide.The choice of material depends on the specific application and the type of material being drilled.
Coating:
- Many industrial drill bits come with coatings to enhance their performance. Common coatings include titanium nitride (TiN), titanium aluminum nitride (TiAlN), and black oxide. These coatings provide additional hardness and reduce friction, resulting in better wear resistance.
Drill Bit Types:
- There are various types of industrial drill bits, each designed for specific materials and applications. Common types include twist drill bits (for general-purpose drilling), spade bits (for large holes in wood), masonry bits (for drilling into concrete or brick), and step drill bits (for drilling multiple-sized holes).
Flute Design:
- The flute is the spiral groove on the drill bit that helps remove material as it drills. Different flute designs are suitable for various materials. For example, a parabolic flute design is effective for metal drilling, while a straight flute may be more appropriate for wood.
Shank Type:
- The shank is the part of the drill bit that fits into the drill chuck. Common shank types include round shanks and hex shanks. The choice of shank type depends on the type of drill being used.
Helix Angle:
- The helix angle refers to the angle formed by the spiral flute around the drill bit. It affects chip evacuation and cutting efficiency. Different helix angles are suitable for different materials.
Size and Diameter:
- Industrial drill bits come in various sizes and diameters to accommodate different drilling requirements. The appropriate size is crucial for achieving accurate and efficient results.
Application-specific Drill Bits:
- Some industrial drill bits are designed for specific applications, such as hole saws for cutting large-diameter holes, countersink bits for creating beveled openings, and auger bits for deep drilling in wood.
Coolant and Lubrication:
- In industrial settings, especially when drilling hard materials, the use of coolants or lubricants may be necessary to reduce heat and prolong the life of the drill bit. Some drill bits are designed with features to facilitate coolant flow.
Quality and Brand:
- The quality of industrial drill bits can vary, and reputable brands are often preferred for consistent performance and durability. Investing in high-quality drill bits can lead to better results and longer tool life.
In summary, industrial drill bits are essential tools for a wide range of drilling applications. The choice of drill bit depends on factors such as the material being drilled, the type of drill being used, and the specific requirements of the task at hand.

User questions & answers
| Question: | Are these made in USA and not engineering and design in usa crap you see ond other products to mislead the american people |
| Answer: | Hi Amanda, Well I've had more time with my KA grinder since I wrote that review. I'm still pleased with the way it operates but have come to realize that grinding times need to be longer than the directions call for. I, too favor a fine grind so have been holding the grinding to a count of twenty (one one thousand, two one thousand, etc.). Sometimes it helps to pause at ten and shake the grinder lightly to ensure a thorough grinding with no left over whole beans. Enjoy! |
| Question: | Can I use these with a hand drill |
| Answer: | mostly metal, but there is some plastic parts but few. but the barrel and blades are metal... |
| Question: | What's the difference between the viking series and magnum? The magnums are pretty much all we use in our machine shop, fantastic drills |
| Answer: | Read the book that came with the grinder. It tells the exact amount. I grind 3-4 heaping tablespoons of coffee beans at a time for a 12-cup percolator coffee maker and it does a great job. It is so efficient and so easy to use. I like that the grind cup comes off to empty the ground coffee. I highly recommend this product. FYI, I am a 77 year old Granny and am very particular about my household products. I want them to work as stated and I need ease of use. This one rates high in all categories. I have recommended it to several people. I stand by my word too. |
| Question: | Are these life time replacement if they break |
| Answer: | I have alternated grinding coffee and flax seed over the years. Because flax seed makes a sticky slimy gel when wet, I wipe the grinder bowl out with a complete!y dry paper towel. |

User questions & answers
| Question: | Does every bits in this set has different size or this set only contain 3-4 size |
| Answer: | Yes, this can grind a variety of coffee beans and spices including salt. |
| Question: | Are these drill bits intended only for use in metal or would a woodworker benefit from them as well |
| Answer: | 110 VOLT ELECTRIC CHORD |
| Question: | Do these drill bits come with a lifetime warranty |
| Answer: | If I fill it up to the top of the coffee beans holder, the catching basket overflows. So your upper limit is controlled by the basket. If you grind a full basket I can use 2/3rd of the coffee to make my 4 cups Expresso machine. The other third is set aside for the next time.If you have a large Coffee pot you can just grind multiple times to achieve your desired amount. |
| Question: | Are these bits stepped down to fit a 3/8" chuck |
| Answer: | Made in China. Works fine for this style of grinder, not as good as the more expensive burr grinders, but adequate for me. |

User questions & answers
| Question: | Will this product drill through hardened steel? I'm tired of buying bits that say so but go through only mild steel |
| Answer: | 66820 is a set with Mechanics length bits with tri-flat sides. They are shorter lengths vs the longer 44170 Jobber length w/o the tri-flat sides. Tri-flat sides prevent the bits from slipping in a drill chuck. We have seen this preferred in some cases and not by others. Depends on the user and application. |
| Question: | Can these be sharpened if they become dull |
| Answer: | The cutter wheel uses diamonds, so it will sharpen the bit. Follow the instructions on the Drill Doctor, and you will be fine. |
| Question: | how long are they |
| Answer: | my black case is round.JNW |
| Question: | How long is the warranty |
| Answer: | no they do not have 3 flats |
