  • 10 mm diameter suits precise hole-making
  • 5× diameter flute length reaches deeper holes
  • Twister Al geometry reduces cutting forces
  • California Proposition 65 warning applies to this product

Purpose-built aluminium drill

The M.A. Ford Twister Al 5X 3 Flute Drill is designed for machining aluminium and other non-ferrous materials. Its 8.10 mm diameter and three-flute geometry target high material-removal rates in production environments. The tool suits CNC operators and job-shop machinists who need consistent hole quality in soft metals.

Sustained cutting behaviour

The five-times-diameter flute length supports deeper holes without frequent pecking cycles. Three flutes balance chip evacuation and core strength during continuous drilling. The specialised geometry reduces built-up edge formation when running at elevated speeds in aluminium alloys.

Thermal and power characteristics

Polished flutes and a high-shear point lower friction, limiting heat generation in the cut zone. Reduced cutting forces decrease spindle load and power draw on the machine tool. The design promotes quiet, stable operation through the full depth of cut.

Questions about this item

How much heat does the 8.10 mm Twister Al 5X drill generate during continuous use?

The drill is designed for efficient chip evacuation which reduces friction and heat build-up during prolonged drilling operations in aluminium.

What shank size must my drill chuck accept for the 22931890 bit?

The 8.10 mm diameter shank requires a chuck capacity of at least 8.10 mm or a 3/8 inch chuck for secure clamping.

Will the 3-flute geometry of this 8.10 mm drill work with my older pillar drill?

Yes, the 3-flute design provides stable cutting action compatible with standard pillar drills and handheld units at appropriate speeds.
