Details
- Resistant: Drill body and cutting edges made from the same HSS steel. This results in increased impact and shock resistance – ideal for assembly, steel construction and rough surfaces.
- Minimal friction: TiN coating heat-resistant up to 650°C - for maximum performance and service life.
- Durability: 170 holes = 3.4 m total service life. Determined under optimal conditions (Ø 18 mm, S235, 20 mm).
- Fast & efficient: Higher cutting speeds thanks to TiN - for noticeably more work progress.
- Versatile: Ideal for steel up to 750 N/mm², stainless steel, aluminium - also suitable for short-term dry drilling.
- Experience since 1977: Decades of core drilling expertise – your advantage in practice.
- Accessories: 100 mm centring pin. Order number: 63134998310.
