Best Drill Bit For Stainless Steel Buying Guide & FAQ

Drill Bits for Stainless Steel Vs Hardened Steel

Before you choose a drill bit to drill through stainless steel or hardened steel, you need to understand how these two steel types are manufactured. Hardened steel is manufactured with a high proportion of carbon in it. And, it’s also manufactured after treating the raw metal with a heat treatment and tempering process.

On the other hand, the distinct characteristic of stainless steel is that it’s made of about 10% chromium. As a result, it is fully resistant to stain, rust and corrosion.

Now, when it comes to choosing a drill bit for these two types of steel, choosing the same type of drill bit for both of these types will not be a good decision.

To be more specific, for hardened steel, we recommend that you choose those drill bits that are manufactured with cobalt coatings. The cobalt coating makes the drill bits fully suitable to pierce through hardened steel molecules without any hardship.

On the flip side, if you want to drill through stainless steel, our recommendation is that you choose a TCT ( Tungsten Carbide tipped) drill bit. The specialty of the TCT drill bit is that it’s got tungsten as its coating.

As a result, even if a lot of heat is generated when drilling through stainless steel, the drill bit will not be damaged (thanks to the resiliency of Tungsten).

Frequently Asked Questions

What is the best type of drill bit for stainless steel for all projects?

High-Speed Steel (HSS): This is the most common type of drill bit and can be used on a range of materials including stainless steel.

Carbide (Carb): This is the strongest type of drill bit and is best suited for drilling into hard materials such as stainless steel.

Cobalt (Co): This is a more expensive type of drill bit that is designed to drill into tougher materials such as stainless steel.

The best type of drill bit for stainless steel will depend on the project you are working on. If you are drilling into a softer material, then a high-speed steel (HSS) bit will be sufficient. However, if you are drilling into a harder material, such as stainless steel, then you will need a carbide (carb) or cobalt (Co) bit.

These bits are more expensive but will be able to drill through the stainless steel more easily. Ultimately, the best type of drill bit for your project will depend on the material you are drilling into and your budget.

What is the difference between M35 and M42 cobalt drill bits?

 M35 cobalt drill bits are made of a high-speed steel with a cobalt content of at least five percent. They are designed for drilling in difficult-to-machine materials such as stainless steel and cast iron. M42 cobalt drill bits are similar to M35 bits, but they have a higher cobalt content (eight to ten percent). This makes them even more durable and better suited for drilling in very hard materials.

What is the difference between 118 degrees and 135-degree drill bits?

118-degree drill bits are the most common type of drill bit. They are used for general purpose drilling in wood, metal, and plastic. 135-degree drill bits are used for drilling in harder materials such as stainless steel or cast iron. They have a sharper point and cutting angle than 118-degree drill bits.

Will a masonry drill bit work on stainless steel?

The short answer is yes, a masonry drill bit can be used on stainless steel. However, there are a few things to keep in mind before drilling into stainless steel.

First, masonry drill bits are designed for use with a hammer drill, which will not be necessary (and could actually damage the stainless steel).

Second, masonry drill bits have a much shorter lifespan than standard drill bits, so be sure to have plenty of extras on hand.

Finally, masonry drill bits are not as accurate as standard drill bits, so be prepared for some trial and error. With these things in mind, drilling into stainless steel with a masonry drill bit is perfectly possible just be sure to take your time and go slowly.
