8.30 mm coolant drill — what it is

This M.A. Ford HPDCR 0830A Twister HPD coolant drill is a high-performance cutting tool with a 5x diameter drilling depth capability. It is manufactured for precision holemaking in demanding industrial applications where coolant-through operation is required. The 8.30 mm diameter suits specific machining tasks in metalworking environments.

Suited for coolant-through machining.

This drill serves machinists and fabricators who run coolant-fed drilling cycles on compatible machine tools. It is not intended for handheld use, dry drilling operations, or applications lacking through-spindle coolant delivery. Buyers needing larger diameters, different flute lengths, or non-coolant tooling should select alternative products.

8.30 mm diameter with 5x depth capability

The defining specification is the 8.30 mm cutting diameter combined with a 5x diameter drilling depth ratio. This determines the maximum hole depth achievable in a single pass and must match the workpiece thickness and machine capacity. Verify the 8.30 mm size against your drawing requirements before ordering.

Questions about this item

How much heat builds up when the 8.30 mm HPDCR drill runs continuously in steel?

The through-coolant design flushes heat from the cut zone, keeping the 8.30 mm tip stable during extended drilling cycles.

What machine setup is needed to use the coolant-fed 8.30 mm Twister drill?

A spindle with through-coolant capability and an 8.30 mm tool holder are required to supply fluid to the drill’s internal channels.

Will the 8.30 mm HPDCR drill fit the same holder as my older 8 mm solid drills?

Yes — the 8.30 mm shank matches standard 8 mm collets, so existing holders accept it without adaptation.
