Drilling through tough stuff like stainless steel or cast iron? Regular bits just won't cut it. You need the BECOLLO 7/64 Inch Cobalt Drill Bit Set. This 20-piece set is built for the hard jobs that make other bits quit.
These bits are made from premium M35 Cobalt High-Speed Steel (with 5% cobalt). That means they resist heat and wear way better than standard HSS bits, giving them a much longer life. They go through hard metals like a champ while staying sharp.
The 135° Split Point design is a game-changer. It helps the bit self-center on your mark, preventing it from \walking\ or skating across the surface when you start drilling. This means cleaner, more accurate holes and less frustration.
The entire bit is fully ground for a super smooth surface, which reduces friction and lets you drill faster. They're jobber length, which is the perfect all-purpose size for most projects. The set comes in a handy plastic case to keep all 20 bits organized and protected.
Remember: For best results on thick metal, use a drill press if you can, start at a low RPM, keep the bit perpendicular, and use a cutting fluid or coolant to manage heat. These bits are perfect for stainless steel, cast iron, and other hard metals. (Just don't use them on hardened or heat-treated steel). Get the right tool for the job and make metal drilling easy!
