M.A. Ford HPDCR 0790A Twister Drill

The M.A. Ford HPDCR 0790A Twister HPD coolant drill is a solid carbide cutting tool designed for high-performance drilling in demanding materials. It targets machinists and maintenance technicians who require precise hole-making with integrated coolant delivery.

7.90 mm diameter with 5X coolant holes

The defining specification is the 7.90 mm cutting diameter combined with five internal coolant channels that feed fluid directly to the cutting edges. This geometry ensures consistent chip evacuation and temperature control in deep-hole applications where external flood coolant cannot reach.

Five coolant channels for deep holes

The five through-coolant ports comfortably handle deep drilling cycles in steel, stainless alloys and high-temperature metals where heat buildup typically limits tool life. The design runs out when the machine spindle cannot supply sufficient coolant pressure or when the workpiece material exceeds the carbide substrate’s hardness range.

Questions about this item

What hole size does the 7.90 mm drill produce in practice?

The drill cuts a 7.90 mm diameter hole when used with coolant at the recommended speed and feed.

What shank interface does the Twister HPD drill use and what does it limit?

It uses a standard round shank that fits common drill chucks and collets, limiting use to holders that accept that shank diameter.

What physical space is needed to mount the 5X coolant drill?

The 5X length requires a holder and workpiece clearance long enough for the full flute and shank engagement.
