  • California Proposition 65 warning informs safe handling practices

Professional drilling tool

The M.A. Ford Twister Xd 3X is a solid carbide drill with a 9.40 mm cutting diameter. It is designed for machinists and maintenance engineers who need accurate holes in tough materials. The carbide construction provides high wear resistance and long tool life. This accessory fits standard drill chucks and CNC holders.

Upgrade from HSS drills

This drill replaces conventional high-speed steel bits when cutting hardened steels, stainless alloys or abrasive composites. The jump is worth it when hole quality and tool longevity outweigh the higher initial cost. It reduces the frequency of tool changes on long production runs. The 3X geometry improves chip evacuation in deep holes.

Simple holder mounting

Installation requires clamping the cylindrical shank into a collet, chuck or hydraulic holder with adequate grip force. Runout should be checked before starting the spindle. What usually goes wrong is insufficient coolant pressure or incorrect feed rates causing premature flank wear. Always verify the workpiece is rigidly fixtured.

Questions about this item

What shank size matches the 9.40 mm Twister XD drill for a standard collet or chuck?

The drill has a 9.40 mm diameter shank, so use a 9.40 mm collet or a three-jaw chuck that closes fully on that size.

Which step is most often missed when installing this solid-carbide drill in a CNC holder?

Clean the holder bore and drill shank with solvent, then torque the collet nut to the holder maker's spec — skipping the cleaning leaves oil that lets the drill slip.

When should the 2XDSS3701A drill be replaced rather than re-sharpened?

Replace it when the corner radius shows visible wear or the margin lands are uniformly rounded, as the XD coating cannot be economically restored.
