【10PCS 5mm Cobalt Drill Bits】10pcs -(Dia 5mm) x (Length 86mm) metal drill bits. This drill fits most power drills on the market today and comes with a portable plastic case for easy storage and organization..
【M35 Cobalt High Speed Steel】Made of M35 Cobalt Steel, Cobalt is added to form a hardened alloy, measuring Rockwell hardness up to 67, faster cutting speed, longer service life, up to twelve times more drill bits compared to ordinary high speed steel. HSS bit set, harder than the 4241 HSS used in other similar bit sets. These bits also contain 5% cobalt for improved wear resistance and durability..
【Full Grinding Process and 135° Split Point】Fully ground helical flute design removes particles quickly, reducing friction and heat for faster, cooler drilling performance. The 135° straight shank split point prevents walking, making drilling more precise and faster..
【PROFESSIONAL AND WIDELY USED】M35 Cobalt High Speed Steel is more suitable for hardening materials. Ideal for cutting stainless steel, steel and cast iron as well as wood, aluminum alloys and other metals. Not suitable for glass or ceramic materials. Pay attention to speed, pressure and heat control when drilling..

MADE FROM HIGH-SPEED STEEL AND 5% COBALT: improve much higher heat resistance because of cobalt steel's high red hardness, provide strong durable performance compared to typical hss drill bits.
CAN BE REPEATEDLY SHARPENED AS NEEDED: cobalt drill bit's hardness is uniform throughout the entire material, so that can be repeatedly sharpened without damaging the cutting edge allowing it to drill more than hss drill bits.
APPLICATION: best used for drilling in hard metal, including stainless steel.
INCLUDE: 12 pieces of 3/32-inch cobalt drill bits with case.
