Know About Cobalt Drill Bit Cobalt drill bits are not made of pure cobalt, but rather a steel alloy with certain percent cobalt. The 5-percent alloy is known as M35 grade. The cobalt increases the strength of the steel and makes it more heat-resistant; this is an important factor in drilling hard materials because the friction of metal against metal can produce high temperatures that damage the material or the drill bit.
FEAURES: Lowest Cost Per Hole Drilled Cobalt bits are more expensive than ordinary HSS drill bits. But if you regularly drill metals, they are a good investment since they tend to last longer. With an extended life, you can lower cost per hole drilled. Twist Drill Bit Body Heavy-duty, fully ground body construction. High flow spiral design for the fastest removal rate and for thick material. Straight Shank Straight shank for standard drill chuck, less "walkor wander. FUNCTIONS: M35 cobalt HSS drill bit is more suitable for hardened material such as stainless steel, cast iron, aluminum alloy, wood and other soft metals. DO NOT USE ON glass, ceramics, hardened steel, high carbon steel and heat treated steel.
Product Details: Diameter: 1/16 inch Work length: 7/8 inch Total length: 1-7/8 inch Material: 5% Cobalt Package: 10 Pieces
Notice: The working life of the drill bits can be largely prolonged by using with cooling liquid.
