Tivoly 81492610330: metal drill bit, 3.3 mm.
•Split-point grinding:reduction of the drill tip. Enables the simple self-centring of the drill bit on the smoothest of surfaces. Significantly
•reduces the requried axial load.
•28° type N flute : normal flute profile with a 28° helix angle. Suitable for general use. Provides good rigidity to the tool, as well as
•excellent drilling precision.
•8% cobalt high-speed steel : HSS substrate enriched with 5% cobalt. Improved heat retention (strength, cutting sharpness). For general
•use in metals up to 1400 N/mm2;
•135° tip: 135° tip angle for the sharpening of the drill bit. Suitable for strong and difficult materials. Enables a shorter and stronger
•cutting edge, thus prolonging the service life.
•INCOCUT coating : Thickness 2/4μm, hardness 3200 HV, coefficient of friction 0,35, resistance to heat (1100°C). Allows for a significant
•increase in cutting conditions. High oxidation resistance (high temperatures). Only for steel, stainless steel and titanium alloys.
