Twister Al 5X 3 Flute Drill 2.50Mm

The M.A. Ford Twister Al 5X is a 2.50 mm diameter drill bit with three flutes designed for aluminium and similar non-ferrous materials. It suits machinists and fabricators who need a dedicated tool for high-speed drilling in soft alloys. The 5X designation indicates a geometry optimised for chip evacuation in these metals.

Installation and common issues

The bit fits standard drill chucks that accept a 2.50 mm shank, so no special holders are required. Problems usually arise when feed rates are too low, causing the flutes to clog with sticky aluminium chips, or when coolant is omitted and built-up edge forms on the cutting lips.

Compatibility checklist

Verify that your machine spindle runs at the high RPM range recommended for small-diameter aluminium drills. Confirm the chuck or collet grips a 2.50 mm shank securely without run-out. Check that your workpiece clamping prevents vibration, which can snap the narrow flutes. Ensure your safety plan addresses the Proposition 65 warning for listed chemicals.

Questions about this item

How can I confirm the Twister Al 5X 3 Flute Drill is cutting correctly after installation?

What comes with the 22909840 drill and what must I supply separately?

The box contains the single 2.50 mm Twister Al 5X drill; a compatible drill chuck or collet and cutting fluid are not included.

When should I choose the 2.50 mm version over other sizes in the Twister Al 5X range?

Select the 2.50 mm drill when the finished hole must be exactly 2.50 mm in aluminium or similar non-ferrous material.
