GOLD-LINE 30 Weldon core drilling machine, Ø 21 mm

The core drill is optimally suited for: Steel Steel GRP / CFK plastics . Good for: Steel Alu Copper, brass, nickel, tin Cast iron . Can be used with: Steel Alu>10% Si . Properties of GOLD-LINE core drill bits: HSS-XE special steel Made of high-alloy steel HSS-. XE This makes them extremely hard on the tooth tips (up to 68 HRC) Long service life . Step-hardened HSS core drill bit Step-hardened HSS core drill bit as standard This results in extremely hard tooth tips (68 HRC) and still flexible core drill . Completely ground from all material This fine grinding increases cutting performance while reducing friction For longer life . Gold- Tech surface treatment Special machining for longer life . Five cutting geometries Specially adapted cutting geometries specifically for different cutting diameters and depths . Suitable for core drills: Metal Force, Alfra-Rotabest + Alfra Rota-Quick, BDS + BDS Keyless, Bektop, Bux, Euroboor, Evolution, Hougen, Jancy, Magbroach, Magtron, Magnetor, Promag, Rotabroach, Ruko + Ruko Easy Lock, Universal...
