8.50 mm Twister HPD coolant drill

The M.A. Ford HPDCR 0850A is a Twister HPD coolant drill with a 5X design and 8.50 mm diameter. It is intended for machinists and maintenance teams who need a high-performance drill for precision hole-making in metal. The tool ships new directly from the manufacturer.

Coolant-through installation requires compatible

Installation is straightforward when the machine spindle and tool holder support internal coolant delivery at the required pressure. The most common issue is using a holder without through-coolant capability, which prevents the drill from receiving lubrication and leads to premature wear or breakage.

Verify spindle coolant capability

Before ordering, confirm that your machine spindle and tool holder provide through-coolant flow and accept an 8.50 mm shank. Also check that the workpiece material and cutting parameters match the drill's high-performance design. The product carries a California Proposition 65 warning for chemicals known to cause cancer and reproductive harm.

Questions about this item

How do I verify the 8.50 mm Twister HPD Coolant Drill is cutting correctly after setup?

Check that the drill produces consistent chip formation and maintains steady feed without vibration at the recommended speed for the material being drilled.

What is included with the HPDCR 0850A drill and what must be purchased separately?

The package contains the 8.50 mm Twister HPD coolant-through drill only; coolant supply, tool holder, and work-holding fixtures are sold separately.

When should I choose the 5X length version of the 8.50 mm Twister HPD drill?

Select the 5X length when the hole depth required is up to five times the 8.50 mm diameter and coolant-through capability is needed for chip evacuation.
