Twister HPD coolant drill 3.10 mm

The M.A. Ford HPDCR 0310A is a Twister HPD coolant drill designed for high-performance drilling. It features a 3.10 mm diameter and a 5X length-to-diameter ratio for extended reach. This new cutting tool suits precision metalworking tasks requiring internal coolant delivery.

Machinists needing 5X reach with coolant

The drill suits operators who need a 3.10 mm tool with 5X depth capability and through-coolant holes. It is not for buyers who need a different diameter, a shorter or longer flute length, or a non-coolant solid drill. Shops without high-pressure coolant systems cannot use the internal delivery feature.

3.10 mm diameter with 5X coolant design

The single specification that decides fit is the 3.10 mm diameter combined with the 5X coolant-fed geometry. This exact size and length ratio must match the hole requirement and machine spindle capacity. Verify the workpiece material and coolant pressure against the tool design before purchase.

Questions about this item

What machine spindle is required to run the 3.10 mm Twister HPD coolant drill?

A spindle that accepts a 3.10 mm shank and delivers high-pressure coolant through the tool is required.

Can the 5X length drill be used in a standard drill press without through-coolant?

The drill is designed for high-pressure coolant delivery; performance in a standard press without coolant will be reduced.

How do I verify the 3.10 mm drill is cutting correctly after installation?

Check for consistent chip evacuation, steady spindle load and the expected hole diameter of 3.10 mm.
