Metal drill bit HSS-Co 4.2x43x75mm GEPARD (HSS-Co M35 (cobalt 5%), 135 split point angle, cylindrical shank)

Specifications

Purpose

for drilling holes in structural carbon and alloy steels, stainless and heat-resistant steels of strength up to 1000 N/mm2, titanium and its alloys, bronze, brass, non-ferrous metals, cast iron, hard plastic. Spiral drill bit is made of high quality high-speed steel with an already ground profile. Chip output is easier, temperature of heating and run-out of drill in a chuck is less, durability of cutting part is higher. The holes have a high accuracy. Cross cutting edge resharpening allows you to begin drilling without pre-drilling with a pilot drill or a core bit. Increased service life. They have increased productivity, wear resistance and redresistance. Highest precision and accurate drilling. Extra hardness and increased heat resistance due to cobalt in the alloy.
