8.40 mm Twister Al 5X Drill

The M.A. Ford Twister Al 5X is a three-flute drill bit with an 8.40 mm cutting diameter. It is designed for drilling aluminium and similar non-ferrous materials. The 5X designation indicates a length-to-diameter ratio suited for deeper holes. This tool targets professional machinists and maintenance teams.

Suited for aluminium and non-ferrous work

Machinists producing high volumes of accurate holes in aluminium will benefit from the three-flute geometry. Workshops focused on stainless steel, hardened alloys or composite materials should look at alternative tooling. The drill is not intended for hand-held use in wood or masonry applications.

Consistent chip evacuation at depth

The three-flute design promotes steady chip removal during extended drilling cycles. This reduces the risk of clogging and heat buildup when reaching full 5X depth. Cutting edges maintain engagement longer than two-flute equivalents under continuous feed. California Proposition 65 warnings apply to this product.
