Metal drill bit d7*69*D7*109L

High-quality HSS steel alloyed with cobalt (5%) M35, 135° sharpening angle of the drill bit's working part. They are used for drilling materials with high strength and toughness: stainless, carbon and alloy steels, heat-resistant steels, heat-strengthened steels, acid-resistant and corrosion-resistant steels. Cobalt drills are effectively used for drilling holes in welded joints and pipes. The addition of cobalt increases the drill bit's heat resistance without changing the drill bit's properties and allows you to make more holes in a shorter period of time. The drill bit is also suitable for drilling holes in materials such as wood, plywood (fiberboard, chipboard, OSB) and plastic. It is manufactured in accordance with the DIN338 quality standard.
