- Hardness: 64 HRC hard cutting edges – reliable in S235 structural steel and aluminium.
- Durability: 140 holes = 2.80 m total service life (determined under optimal conditions: Ø18 mm, S235 20 mm).
- Sustainable: Can be resharpened multiple times – extends service life, reduces costs.
- Precise: Optimised geometry for fast, clean holes with high dimensional accuracy.
- Experience since 1977: Decades of core drilling expertise – your advantage in practice.
- Accessories: 100 mm centring pin. Order number: 63134998310.
