M.A. Ford Twister Xd 5X Drill 6.40 mm

This solid carbide drill is designed for precision holemaking in demanding materials. It suits professional machinists and maintenance teams who need reliable performance in high-temperature alloys and hardened steels. The 5X diameter design provides extended reach for deeper holes without compromising rigidity. It is not for buyers who need a coated variant or a different diameter for their specific application.

California Proposition 65 chemical notice

The product carries a California Proposition 65 warning for chemicals known to cause cancer and reproductive harm. This notice informs users about potential exposure during handling or machining operations. Proper ventilation and personal protective equipment are standard practices when using carbide tooling. The warning does not alter the drill’s mechanical function or material composition.

Direct manufacturer shipment

The drill ships directly from the manufacturer, which reduces transit handling and ensures the tool arrives in factory condition. No additional accessories, coatings, or software are included in the package. Installation follows standard toolholder procedures for solid carbide drills. Common issues include incorrect coolant pressure or feed rates that can lead to premature wear or breakage.

Questions about this item

How often will the 6.40 mm carbide tip need resharpening or replacement?

Resharpen when cutting edges dull; solid carbide allows multiple regrinds before the 6.40 mm diameter is lost.

What limit appears first during continuous drilling — heat buildup or chip evacuation?

Chip evacuation in deep holes typically limits sustained use before heat becomes critical.

How much heat does the drill generate when running all day in a CNC cycle?

Heat rises with feed and speed; use flood coolant to keep the 6.40 mm tool within safe temperatures.
