Concrete drill bit 4x75mm cylindrical shank Kranz KR-91-0304

KRANZ concrete drill bit is used during construction and renovation work. It is designed for drilling holes in concrete, granite, brickwork, and stone using a drill with a cylindrical shank, which is used in most power tools. Made of tool steel (40cr), ensuring long service life and high performance. The design featuring a stabilizing spiral maintains precise tool positioning during drilling, ensuring uniform distribution of impact load. 2-edge cutting edges easily remove slurry and fine dust particles from the working zone, contributing to maintaining a high working speed. Reinforced cutting edge prevents the tool from jamming in rebar. The drill bit tip features a carbide insert (YG8C) that facilitates efficient penetration into the material, increasing tool durability and reducing wear.
