M.A. Ford Twister Al 5X 3 Flute Drill No 7 22920100

Application Focus

The M.A. Ford Twister Al 5X 3 Flute Drill No 7 is engineered for high-performance drilling in aluminium and non-ferrous materials. Its specialised geometry targets professional machinists and fabricators who require clean hole finishes and efficient chip evacuation in soft, sticky alloys. This tool is not suited for hardened steels, abrasive composites or high-temperature alloys where a different substrate and coating are required.

Sustained Load Behaviour

The 5X diameter flute length supports deeper hole drilling while maintaining consistent chip flow during extended cycles. The three-flute design balances material removal rates with stability, reducing vibration when the tool remains engaged for long periods. Continuous operation in aluminium benefits from the polished flute surfaces that resist built-up edge formation. Heat generation stays manageable without through-coolant, though flood coolant further extends tool life in high-volume production.

Deciding Specification

The 22920100 part number identifies the exact No 7 diameter within the Twister Al 5X series, making it the single reference for reordering and tool-management systems. Verifying this code against the machine programme prevents costly mis-selection, as other diameters in the range share the same flute geometry but differ in cutting limits. No other dimension or coating variant is associated with this specific manufacturer number.
