4.40 mm Coolant-Fed Twister Xd 7X+ Drill

The M.A. Ford Twister Xd 7X+ is a coolant-fed drill bit with a 4.40 mm cutting diameter. It is designed for high-performance drilling in demanding materials where through-tool coolant delivery improves chip evacuation and tool life. This new item suits professional machinists and CNC operators.

Suited for CNC drilling

This drill suits workshops running CNC machines equipped with through-spindle or through-holder coolant systems. It is not for buyers who need a standard twist drill without coolant channels, nor for hand-held drilling applications where coolant feed is unavailable.

Fits holders for 4.40 mm shank tools

The 4.40 mm shank fits compatible tool holders that seal around the shank to direct coolant through the internal channels. This design frees the flutes from chip packing in deep holes and reduces the need for peck cycles. Ensure your holder and machine support through-coolant delivery.

Questions about this item

What machine spindle is required for the 4.40 mm Twister Xd 7X+ drill?

The 4.40 mm Twister Xd 7X+ drill requires a machine spindle capable of accepting a 4.40 mm shank and delivering coolant through the tool holder for internal coolant feed.

Will the Twister Xd 7X+ drill fit in my existing 4.40 mm drill holder?

Yes, the Twister Xd 7X+ drill has a 4.40 mm diameter shank designed to fit standard 4.40 mm drill holders, but verify your holder supports through-coolant delivery for the internal coolant channels.

How can I confirm the Twister Xd 7X+ drill is delivering coolant correctly after installation?

After installation, run the machine at low speed and visually confirm coolant exits through the drill's internal coolant holes at the cutting tip, indicating proper coolant flow through the 4.40 mm tool.
