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.

Questions about this item
What chuck size fits the 11/16 inch shank on this drill?
Use a three-jaw chuck that opens to at least 11/16 inch; the 3-flute shank seats fully when the jaws close evenly on all flats.
How do I start the hole without the 3-flute tip walking?
Centre-punch the spot, then apply light pressure at low RPM until the three cutting lips engage; forcing the feed before engagement snaps the margin.
When should I replace this Twister Al drill?
Replace it when the 3-flute cutting edges show visible rounding or when thrust force rises sharply — regrinding the 5X geometry restores life if the body is intact.
