M.A. Ford Twister Xd 7X+ Coolant Fed Drill

The M.A. Ford Twister Xd 7X+ Coolant Fed Drill is a 6.60 mm cutting tool designed for precision holemaking. It features internal coolant channels that deliver fluid directly to the cutting zone. This design supports efficient chip evacuation and temperature control during operation. It is intended for professional machining environments.

Suited for CNC machining

This drill suits operators running CNC machines equipped with through-spindle coolant systems. The internal coolant feed requires compatible tool holders and machine plumbing to function correctly. Buyers without through-coolant infrastructure should look at external coolant or solid carbide drills instead. Workshops needing larger or smaller diameters must select a different size.

6.60 mm diameter defines the hole size

The 6.60 mm diameter is the single specification that determines whether this drill produces the required hole. It fixes the nominal cut size and matches specific tap drill charts or reaming allowances. If the drawing calls for a different diameter, this tool cannot be used. Verify the required hole size before ordering.

Questions about this item

What shank size must my drill chuck accept to hold the 6.60 mm Twister Xd?

The drill has a 6.60 mm diameter shank, so the chuck must open at least that wide and grip round shanks securely.

Can I run this coolant-fed drill on a machine that only has external flood coolant?

Yes — the tool accepts coolant through its internal channels, but external flood coolant will still reach the cutting zone, though chip evacuation may be less efficient.

How do I confirm the 7X+ geometry is cutting correctly after installation?

Check for consistent chip formation, steady spindle load, and hole diameter within tolerance at the 6.60 mm size.
