Drill for aluminium alloys
The M.A. Ford Twister Al 5X is a 3-flute drill built for aluminium and similar non-ferrous materials. It targets machine shops and fabricators who need clean holes without built-up edge. The 2.90 mm diameter suits precise tapping and clearance work.
Practical limits of the flute geometry
Three flutes evacuate chips faster than two-flute designs in soft metals, yet the tool still requires peck cycles in deep holes to prevent packing. The 5X designation indicates a length-to-diameter ratio that restricts use to rigid setups; handheld drilling risks breakage. California Proposition 65 warnings apply to this product.
Installation notes and common issues
The drill fits standard collets and chucks that accept 2.90 mm shanks; no special holders are needed. Most failures come from excessive feed rates or insufficient coolant, which welds aluminium to the cutting edges. Orders of $75 or more ship free from the manufacturer.
