M35 Cobalt Drill Bits
KnKut M35 cobalt drill bits are built for the metals that wreck ordinary high-speed steel. The M35 cobalt alloy holds its hardness at the high temperatures drilling builds, so the bit keeps cutting instead of dulling and polishing the hole, exactly what you need in stainless steel, titanium, high-strength alloy steel, and other work-hardening metals. Mechanics, body shops, fabricators, and custom car, Jeep, and off-road builders run them on stainless fasteners, exhaust, and high-strength panels. They come in fractional sizes from 1/16" to 1/2" by 64ths, heavy-duty and USA made. Want a full range in a case? See our M35 cobalt drill bit sets.
