ø3.00 mm 5D Solid Carbide DrillNo Internal Coolant · External Flood Compatible

The 5D ratio extends capability beyond standard depth without requiring the higher tooling cost of through-coolant drills. With external flood coolant and correct chip-breaking cycle, the 5D solid carbide drill achieves consistent hole quality in structural steel, cast iron, and aluminium alloys. A cost-effective choice when machine spindle does not support internal coolant.

Where This Tool Excels

ø3.00mm 5D — recommended applications

  • ▸ PCB sub-assembly fixtures
  • ▸ Small instrument housings
  • ▸ Jig & fixture components
  • ▸ Prototype precision parts
Machining Tip: At ø3.00mm, use compressed air rather than flood coolant to prevent re-cutting of fine chips. Feed rate 0.04–0.08 mm/rev; spindle speed up to 8,000 RPM depending on material.
Coolant Advice: Compressed air or light oil mist recommended. External flood coolant acceptable at lower feed rates.
