Single Fluted Gundrill

Single flute gun drills for high L/D ratio deep hole drilling.

Gole Tools manufactures single flute gun drills designed for precision deep hole drilling where straightness, surface finish and process stability are critical.

Tool Design & Construction

  • Tungsten carbide head for high wear resistance and edge stability.
  • Brazed construction ensuring rigidity and alignment.
  • Designed for high-pressure coolant-through operation.

Coolant Flow & Chip Evacuation

  • Coolant is delivered through the internal tube directly to the cutting edge.
  • Chips are evacuated along the V-shaped groove on the tool.
  • Different oil hole configurations are available based on application requirements.

Gole Driver Types

Driver selection is important because the driver connects the gun drill to the machine spindle, transfers torque, supports correct clamping and helps maintain repeatable drilling accuracy.
