Note: RPM values are calculated for the 1,83 mm diameter. Always start at 70% of recommended values and increase based on machine stability and chip formation.

Operating Guidelines

  • Coolant: High-pressure internal coolant (minimum 20 bar) is strongly recommended for holes deeper than 1.5×D. Use water-miscible emulsion (5–8% concentration) or neat oil.
  • Peck Cycle: For depths exceeding 2×D, employ a peck drilling cycle with retract to clear chips. Peck depth = 0.3–0.5×D; full retract every 2×D.
  • Entry Angle: Ensure the workpiece surface is perpendicular to the drill axis. For angled or curved entry, use a spot drill or center drill first.
  • Run-out: Maximum tool run-out must not exceed 0.01 mm at the tool tip. Verify collet/chuck condition before each use.
  • Pre-drilling: Not required for this self-centering point geometry on flat surfaces. For cast or forged surfaces, spot-drill to prevent wandering.
  • Speed & Feed Ramp: Reduce spindle speed by 20% and feed by 10% for the first 5 holes to break in the cutting edge.
  • Chip Inspection: Target short, curled chips (C-shape or 6-shape). Long stringy chips indicate insufficient feed; powdery chips indicate excessive speed.
