Questions about this product

What makes these M35 cobalt bits better for drilling stainless steel than standard drill bits?
These bits contain M35 cobalt high-speed steel, which hardens them to 64-66 HRC. This specific alloy maintains its sharp cutting edge under extreme heat. Standard bits quickly dull when drilling hardened metals, but these resist that heat.
What speed settings should I use so these tiny drill bits don't snap?
You should run these small diameters at a high speed range between 2000 and 5000 RPM. Because they are very thin, light pressure and high speeds prevent binding. Always use a steady hand or a drill press to keep them from bending.
Will these straight shank bits fit into my standard hand drill or rotary tool?
Yes, the straight shank design fits securely into all standard drill chucks, collets, and press vices. The shank size is likely 3mm or 1/8-inch for the smallest bits. They work perfectly in right-hand rotation drills.
