Twister XD 5X solid carbide drill

The M.A. Ford Twister XD 5X is a solid carbide drill designed for precision holemaking in a variety of materials. Its 4.70 mm diameter suits applications requiring that specific size. The tool is supplied new and carries California Proposition 65 warnings for cancer and reproductive harm.

Stepping up from standard HSS drills

Solid carbide construction provides greater rigidity and heat resistance than conventional high-speed steel bits. The upgrade is worthwhile when longer tool life and tighter tolerances are needed in repetitive drilling operations. The 5X designation indicates a length-to-diameter ratio suited for deeper holes.

Suited for CNC and rigid setups

This drill performs best in controlled machine environments where runout is minimised and coolant can be applied effectively. It is not intended for hand-held use or flexible drill presses where vibration would risk carbide fracture. Buyers needing larger diameters or different lengths should select an alternative specification.

Questions about this item

What shank diameter does the 4.70 mm Twister XD 5X drill need in the chuck?

The drill has a 4.70 mm shank, so it fits any standard chuck that accepts 4.70 mm round shanks.

What is the correct peck-drilling step to avoid chip packing in this 5X solid carbide drill?

Use short peck cycles at the recommended feed rate; the most common error is running too few pecks, which lets chips weld in the flutes.

When should the 2XDSR1850A drill be replaced rather than resharpened?

Replace it once the corner radius wears past the manufacturer’s regrind limit or if the carbide shows micro-chipping that resharpening cannot remove.
