⭐️⭐️⭐️⭐️⭐️
Just added this M35 cobalt drill bit set (1.5–6.5 mm) to my toolbox—and wow! These bits cut through stainless steel, cast iron, and hard metals with ease. The 5% cobalt alloy stays sharp much longer than regular HSS, and the 135° split point starts holes cleanly with zero walking.Shanks are straight and fit tightly in my drill press and cordless driver. Flutes evacuate chips well, and overheating is minimal even on prolonged use. The set is compact (13 bits) and came with a simple plastic case that keeps sizes organized.If you need tough, reliable metric bits that don’t crumble on hardened metal—this is it. Great value and performance. 5/5!

Nice drill bits.
Used these to drill out some holes in 3d prints. They work as expected. Will buy again.

Perfect sized bits for needed metric holes.

Decent aid for auto mechanic tasks.
Much appreciated diameters - though maybe not quite as accurate in size as could be.
