Top 10 Best 11/64 Drill Bit

Cobalt M42 drill bit provides upgraded M42 Cobalt jobber-length bits designed for durability, high heat resistance and Hardened surface for stainless steel, cast iron, titanium, light-gauge metal and aluminum. Enhanced M42 alloy material contains 8 Cobalt alloy that delivers 10x life vs. Standard bits. High-heat resistant bits withstand high-temperature applications for extended periods of time. Thick web-helix design provides additional stability in tough applications. Surface-hardened tip penetrates tough abrasive materials.

JOBBER LENGTH 1164-inch cutting diameter, 2-18-inch flute length, 3-14-inch overall length, 135 degree split point, straight shank. 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 1164-inch cobalt drill bits with case.
