Product Description
Drill bit set for core hole tapping
The HSSE twist drill with 5 % cobalt content (M35) and titanium-nitride coating (TiN) or titanium-aluminum-nitride coating (AlTiN) is the ideal choice for demanding drilling work in industrial production and in trade. Due to the higher proportion of cobalt, HSSE has a significantly higher hardness and temperature resistance compared to HSS. The drill bits are precision ground and have high concentricity and pitch accuracy.
Technical data:
- Manufactured according to DIN 338
- Material: HSS-E (M35 with 5 % cobalt)
- Shank: Cylindrical
- Cutting direction: Right-hand cutting
- Type: N-HD
- Coating: Titanium nitride (TiN) or titanium aluminum nitride (AlTiN)
- Point angle: 135°
- Bevel: Cross bevel
Selection of the coating
Coatings protect the cutting edges of the drill against abrasive wear and ensure a reduction in cutting forces. A significant increase in efficiency can be achieved, particularly in series production, thanks to higher feed rates and fewer tool changes.

TiN coating The TiN coating (titanium nitride) is a multi-layer wear protection coating that is characterized by a smooth surface and very good ductility. Application temperature up to 600°C Application: Steel (< 900 MPa), aluminum, brass, copper, titanium alloys and plastics |
 |
TiAlN coating The TiAlN coating (titanium aluminum nitride) is a multi-layer wear protection coating that is applied to the cutting edges using the PVD process. The resulting oxidation resistance and high hardness lead to a significant increase in service life. Application temperature up to 800°C Application: Steel, stainless steel, gray and malleable cast iron, hardened steel up to 40 HRC |
