Details

Problem solver: Precise drilling up to 75 mm cutting depth – ideal for compensating for height differences between the machine and the component.
Impact and shock resistance: tough cutting edges and robust HSS body with 64 HRC – reliable in S235 structural steel.
Durability: 36 holes = 1.80 m total service life. Determined under optimal conditions (Ø 24 mm, S235, 50 mm).
Efficient for deep drilling: wide flutes for optimum chip removal – prevents chip build-up and protects against jamming.
Sustainable: Can be resharpened multiple times – extends service life, reduces costs.
Experience since 1977: Decades of core drilling expertise – your advantage in practice.
Accessories: Centring pin 125 mm. Order number: 63134998330.
