Grąžtas suvirinimo taškams Tivoly HSS-CO 5%, 8mm

•Sheet metal cutting: with centring tip and lip. Circular and burr-free drilling of thin sheet metals. Suitable for the misalignment of weld points.
•Cylindrical shank: the diameter of the shank is equal to the diameter of the tip. Enables versatile use on portable electrical tools and CNC machine tools.
•30° type N flute: normal flute profile with a 30° helix angle. Suitable for general use. Provides good rigidity to the tool, as well as excellent drilling precision.
•5% cobalt high-speed steel: HSS substrate enriched with 5% cobalt. Improved heat retention (strength, cutting sharpness) For general use in metals up to 1200 N/mm2.
•FUSIO coating: Ti2CN base, thickness 2/4μm, hardness 3200HV, coefficient of friction 0.2, heat resist. 400°C. Thermal Thermal shield. Allows you to significantly increase service life, cutting speed, and progress. Reduces the axial load. Especially for steels.
