M35 Cobalt Drill Bit Set, 13/19/25pcs
Made from M35 5% Cobalt HSS, these cobalt drill bits are ideal for processing hard materials, including stainless steel, cast iron, high-temperature alloy, titanium alloy, hard plastics, and woods.
The precise 135° split point prevents the bit from wandering.The 2-flute design helps to clear chips and debris away from the bit, reducing friction and heat for a faster, cooler drilling process.
Tips:
Because the speed of the electric drill is too fast, pay attention to the speed regulation when drilling (recommended speed: 100-1000r/min) The larger the diameter of the electric drill, the slower the speed requirement.

I was trying to repurpose an old steel bedframe and my drill bits could barely make a dent. I wouldn’t say theses go through it like butter, but they’re not having any trouble going through it. I still have a lot of holes to drill, so if they dull after al the holes are completed I’ll come back and edit this review.

I needed to drill through a 0.8mm piece of copper to make a sail for some wind chimes. These bits cut right through with no problem! A FIVE-STAR product for sure!
