Drill purpose and user
The M.A. Ford HPDCR 0390A Twister HPD Coolant Drill is a 3.90 mm high-performance drill designed for coolant-fed drilling operations. It suits machinists and maintenance technicians who need precise hole-making in metal components using a 5X diameter-to-length ratio tool. The drill is sold new and ships directly from the manufacturer.
Installation notes
Installation requires a machine spindle capable of delivering coolant through the tool holder at adequate pressure for the 5X length. Misalignment or insufficient coolant flow typically causes premature wear or breakage, so rigid workholding and correct run-out settings are essential before starting the cycle.
Sustained load behaviour
Under continuous cutting the drill maintains consistent chip evacuation through its internal coolant channels, reducing heat buildup at the cutting edges. Steady feed rates and stable spindle speed prevent deflection in the longer flute section, allowing the tool to complete deep holes without wandering or thermal damage.

Questions about this item
How do I verify the 3.90 mm Twister HPD drill is cutting correctly after setup?
Check that coolant flows through the internal channels and that the 5X flute geometry produces consistent chip evacuation at the rated diameter.
What comes in the box with the HPDCR 0390A and what must I supply separately?
The drill itself is included; you must provide a compatible coolant-fed holder, machine spindle and cutting fluid.
Which capacity of the Twister HPD series should I choose for a 3.90 mm hole?
Select the 0390A variant, which is manufactured to a 3.90 mm cutting diameter and 5X flute length.
