When it comes to drilling through stainless steel, not all drills are created equally. Stainless steel is a tough and durable material that requires specialized drill bits that can withstand high temperatures and maintain their cutting edges. Here, we will explore the different types of drill bits available for stainless steel and provide you with tips for selecting the right tool for your holemaking operations.

Hardened steel properties

When it comes to drilling through stainless steel, there are a few key factors to consider. One of which is that the material is prone to hardening, which means that it becomes harder and more difficult to drill as you continue to work on it. Additionally, stainless steel is a poor conductor of heat, which means that it can quickly become hot during the drilling process.

Carbide drill bits are the most durable and long-lasting type of drill bits available. They are extremely durable and can withstand the high-temperatures and pressures of drilling stainless steel.

What is hardened steel used for

Now that we've covered some of the key factors to consider when selecting drill bits for stainless steel, let's take a closer look at some of the specific types of drill bits that are best suited for this material.

Last week Wright Aeronautical Corp. announced that it has developed a machine grinder which hones 18 cutting tools at once to a razoredge impossible with hand grinding. Result: the tools heat much more slowly, wear from 10 to 20 times as long.

To overcome these challenges, it is essential to choose the right drill bit for the job. Here are some of the factors to consider when selecting drill bits for stainless steel:

Drilling stainless steel requires the right techniques and tools. Using lubricant, starting with a smaller bit, securing the material, using the right speed, and applying the right pressure will help you easily drill stainless steel. With these tips, you can achieve a smooth and accurate drilling experience for your machining operations.

The skilled human hand lost another small round against the machine last week, and U.S. industry thereby took an important stride toward solving one of its most acute wartime bottlenecks—cutting tools. Such tools (used to cut gears, shafts and engine parts from hard alloy steels) are themselves made of even harder tungsten, cobalt and molybdenum steels. Nevertheless, they dull quickly, must be constantly reground. Previously such grinding was done by hand. This method is maddeningly slow, and even the most efficient hand grinding produces a cutting edge which, viewed through a microscope, looks like the blade of a saw. Red-hot metal caught between these minute saw teeth causes cutting tools to overheat quicker, wear out sooner.

Drilling through stainless steel can be a challenging task, but with the right techniques and tools, it can be done with ease. Here are some tips to help you drill through stainless steel with ease:
