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.
