Metal drill bit HSS-G TIN 7.0x69x109mm GEPARD (HSS-G M2, TiN coating, 118 split point angle, cylindrical shank)

Specifications

Purpose

for drilling holes in structural carbon and alloy steels, non-ferrous metals, cast iron, bronze, copper-nickel alloys, graphite, 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 in a chuck is less, durability of cutting part is higher. The holes have a high accuracy. Cross cutting edge resharpening allows you to start drilling without pre-drilling with a center drill or a core bit. Increased service life; Type of drill bit surface treatment
