Product Description

Drill bit for the precise drilling of steels and cast irons, thanks to its self-centring cut.

118° Tip: 118° tip angle for sharpening. Suitable for general use in materials with long shavings. Enables rapid attachment and simple centring.

Split-point Grinding: Reduction of the drill tip. Enables simple self-centring on smooth surfaces and significantly reduces required axial load.

Cylindrical Shank: Diameter of shank equals tip diameter. Versatile use on portable electrical tools and CNC machines.

30° Type N Flute: Normal flute profile with 30° helix angle. Provides good rigidity and excellent drilling precision.

High-speed Steel: HSS substrate for general use in steels and cast irons up to 950 N/mm².
