Application

For centre drilling on CNC machines.

Execution

  • spiral-fluted design with relief grinding. diameter 0.5–0.8, ground on one side
  • Packing unit: Ref. no. 005 - 025 = 10 units (price per unit)

Advantage

  • less risk of centre drill breakage, since the radius does not leave behind sharp edges
  • radius compensates for positioning inaccuracies and angle errors (sufficient bearing surface present even with offset lathe centre)
