M.A. Ford 15.40 mm Coolant Drill

The M.A. Ford HPDCR 1540A Twister HPD is a coolant-fed drill engineered for high-performance drilling applications. It features a 15.40 mm diameter and a 5X length-to-diameter ratio designed for deep-hole accuracy. The tool is supplied new and ships directly from the manufacturer.

Suited for deep-hole drilling in metal

This drill suits machinists and fabricators who require through-coolant capability for chip evacuation and temperature control in deep bores. It is not intended for hand-held use or for shallow holes where a standard twist drill is sufficient. Buyers needing a non-coolant design or a different diameter should select another tool.

15.40 mm diameter with 5X ratio

The defining specification is the 15.40 mm cutting diameter combined with the 5X length-to-diameter ratio. This determines the maximum drill depth and the required spindle clearance for the workpiece. Verify that your machine and fixture accommodate this specific geometry before purchase.

Questions about this item

Does the 15.40 mm drill generate noticeable heat during extended use?

The Twister HPD coolant-through design routes fluid directly to the cutting zone, keeping the 15.40 mm tool cooler during long drilling cycles.

What machine setup is required to use the coolant-fed 15.40 mm drill?

A CNC or drill press with through-spindle coolant delivery and a 15.40 mm capacity chuck is needed to run this drill.

Will the 15.40 mm coolant drill fit in my older tool holder?

The shank follows standard industry dimensions for 15.40 mm high-performance drills, so it fits existing holders that accept that diameter.
