M.A. Ford Twister Al 5X 3 Flute Drill 11/16 22968750

What this drill is and who uses it

The M.A. Ford Twister Al 5X is a three-flute cutting tool sized at 11/16 and identified by part number 22968750. It is designed for machining aluminium and similar non-ferrous materials in professional workshop environments. The 5X designation indicates a geometry optimised for higher feed rates in those alloys. Buyers needing a drill for hardened steel, exotic alloys or high-volume production lines should look elsewhere.

What it replaces and when to switch

This drill replaces standard two-flute or general-purpose bits when aluminium chip evacuation becomes a bottleneck. The three-flute design and 5X geometry allow faster material removal without recutting chips, so the jump is worth it when cycle time on non-ferrous parts is limiting throughput. It does not address vibration issues in deep-hole drilling beyond its own length, nor does it suit interrupted cuts in castings.

Installation notes and common issues

The drill fits any holder that accepts an 11/16 shank; no special collets or adapters are required. Common problems arise when coolant pressure is too low to clear the additional flute, causing built-up edge, or when the workpiece is not rigid enough for the higher feed rates the 5X geometry enables. California Proposition 65 warnings apply to this product.
