Specification
25 pieces Long, precise, high-performance drill for deep drilling in stainless steel (e.g. V2A, V4A), heat-resistant steels and titanium. Also suitable for general broader applications in steel with strength up to 1,000 N/mmu00b2 and in cast iron.

Rapid drilling with perfect chip removal

Large chipping spaces and small core

Ideal for producing core drill holes

Highly precise tip grinding for precise drilling

Notice
  • When using the twist drill according to DIN 340, prior drilling of a centring bore is recommended. Our NC spotting drills (art. no. 063644 etc.) are perfectly suited to this.
  • Also recommended in conventional steel if longer service life compared to uncoated HSS drills is a priority.
  • See overview tables for drill/material assignments
