M.A. Ford HPDCR 0940A Twister HPD Coolant Drill 5X 9.40 mm

SKU CH-NV2A-A77XP

A 9.40 mm high-performance coolant drill designed for 5X drilling depth

  • Precision drilling at 9.40 mm diameter
  • Five-times coolant-fed design for heat control
  • Twister HPD geometry improves chip evacuation
  • M.A. Ford manufacturing for consistent quality
  • California Proposition 65 chemical warning applies

Drill Specifications

The M.A. Ford Twister HPD coolant drill measures 9.40 mm in diameter and is designed for high-performance drilling tasks. It suits machinists and maintenance technicians who need a dedicated coolant-fed tool for precise hole-making in metal.

Thermal And Power Notes

The coolant-through design directs fluid to the cutting zone, helping manage heat during extended operations. This reduces thermal buildup on the workpiece and the tool itself, supporting consistent performance without external flooding.

Upgrade Context

This drill replaces standard twist drills that rely on external coolant or dry cutting in similar diameters. The jump is worth it when internal coolant delivery improves chip evacuation and tool life in deep-hole applications. California Proposition 65 warnings apply for cancer and reproductive harm.

Questions about this item

How is the 9.40 mm coolant drill installed in a CNC holder, and what step is often missed?

Clamp the shank at the 5X flute length, then engage the through-coolant port before tightening; skipping the port alignment starves the drill of coolant.

What maintenance does the Twister HPD drill need after extended use?

Inspect the 9.40 mm cutting edges for wear and clear chip buildup from the coolant channels; replace the drill when flank wear exceeds the supplier limit.

Which limit appears first during sustained high-speed drilling with this tool?

Thermal buildup at the 9.40 mm tip typically triggers the Prop 65-listed coating breakdown before mechanical wear becomes critical.
