Feature
●COBALT STEEL - Made from M35 5% cobalt steel, with molybdenum and cobalt to create a hardened alloy, with Rockwell hardness up to 65, for much faster cutting and extra longer life, with up to 10 times compared to an average HSS drill bit.
●HSS Titanium Coating - Classic HSS construction with titanium coating for high strength and durability. The cutting edge is hardened and ground for sharpness.
●FLUTE SHAPE - 2 flute shape helps remove chips and debris from the bit, reducing friction and heat for a faster, cooler drilling process. Chatter-free design with offset cutting teeth ensure precise countersinking and smooth cleaning.
●STRAIGHT SHANK & 135° TIP ANGLE - Straight shank for standard drill chucks and collet chucks for firm grip and precise centering; Spiral groove to easily remove chips; Ideal for general purpose drilling applications.
●FOR METALWORKING - Particularly successful in cutting carbides (hardness less than Hrc38°) such as stainless steel and cast iron, although they can also be used for softer materials such as copper and aluminum. Not for hardened steel and high carbon steel.
