Details
- Problem solver: Extra-long design for precise drilling up to 100 mm cutting depth – compensates for height differences between the machine and the workpiece.
- Impact and shock resistance: tough cutting edges and robust HSS body with 64 HRC – reliable in S235 structural steel.
- Durability: 24 drill holes = 1.20 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.
