Twister HPD Coolant Drill 5X
The M.A. Ford HPDCR4375A is a high-performance coolant drill designed for precision hole-making in demanding materials. It suits machinists and fabricators who need reliable tool life and consistent accuracy when drilling 7/16 inch diameters at 5X depth.
Thermals noise and power draw
Coolant-through channels deliver lubricant directly to the cutting zone, controlling heat buildup during extended cycles. This reduces thermal stress on the cutting edges and workpiece, supporting stable performance without excessive spindle load or vibration.
Replaces standard jobber drills
The 5X length and coolant capability upgrade from conventional short drills that cannot reach deep features or evacuate chips effectively. The jump is worth it when hole depth exceeds three diameters and flood coolant cannot reach the tip.

Questions about this item
How do I install the 7/16 inch Twister HPD coolant drill into my machine spindle, and what step is most often missed?
Secure the 7/16 inch shank in a matching collet or holder, then engage the through-coolant supply before starting the spindle; the step most often missed is confirming coolant flow through the drill’s internal channels.
What maintenance or replacement will the HPDCR4375A drill need after extended use?
The cutting edges will dull over time; plan to resharpen or replace the drill once hole quality drops or thrust force rises, and inspect the coolant passages for blockage each time you change the tool.
What limit appears first when running the Twister HPD drill continuously at high feed rates?
Heat buildup in the cutting zone typically becomes the limiting factor before spindle power or chip evacuation, so maintain steady coolant pressure and monitor tool temperature during long cycles.
