Precision Twist c60m41co Cobalt Steel Short Length Drill Bit Set with

Description

Compared to standard drill bits, these tools have a thicker web for increased strength and rigidity. The helical twist of the flutes brings chips up and away from the cutting edges and allows for coolant to reach the cutting edges. Short length twist drill bits (also called stub or screw-machine length) are the shortest and stiffest twist drill bits, helping to reduce the chance of deflection or breakage when drilling. Jobber length twist drill bits, the most common length of twist drill bit, offer a good compromise of length and reach to work with the widest range of materials and applications. The self-centering 135-degree split point penetrates hard material without a pilot hole and produces smaller chips, which are less likely to clog a hole than a 118-degree point. Whats in the Box? These short length drill bits have a drilling depth of up to 2.5 times their diameter. 60 drill bits, one each of wire gauge sizes #60 through #1Metal case. The company, headquartered in Crystal Lake, IL, meets International Organization for Standardization (ISO) standards 9001 and 14000. Reduced shank drill bits (also called Silver and Deming drill bits) have a shank that is smaller in diameter than its shaft, permitting drilling machines with either a 1/2" or 3/4" drill chuck to create large holes. The gold oxide finish acts as a lubricant and provides wear resistance. The round shank accommodates most drill chucks.
