Twister XD 3X Coolant Fed Drill 3.50 mm

The M.A. Ford Twister XD 3X Coolant Fed Drill is a 3.50 mm solid-carbide tool designed for high-performance drilling in demanding materials. Its internal coolant channels deliver fluid directly to the cutting zone for improved chip evacuation and temperature control. This drill targets professional machinists and CNC operators who require reliable hole-making in tough alloys.

Suited for high-volume production

The coolant-fed design suits shops running deep-hole or high-speed cycles where heat buildup and chip packing cause premature wear. It is not intended for hand-held use or machines without through-spindle coolant capability. Buyers needing larger diameters or non-coolant geometries should look at alternative series.

3.50 mm cutting diameter

The 3.50 mm diameter is the critical specification that determines fit for a specific hole size. Verify this exact dimension against your drawing or tooling plan before ordering. The 3X designation indicates a length-to-diameter ratio optimised for moderate-depth holes. California Proposition 65 warnings apply to this product.

Questions about this item

What shank diameter does the 3.50 mm Twister XD 3X drill need to fit my collet?

The drill is 3.50 mm in diameter, so it requires a 3.50 mm collet or chuck capacity for a secure fit.

How do I correctly install the coolant-fed drill so the internal channels align?

Insert the drill fully into the holder until the shank seats, then engage the machine's coolant supply to pressurise the through-tool channels before cutting.

When should I replace the Twister XD 3X drill based on wear?

Replace the drill when the cutting edges show visible rounding, the margin width narrows, or hole size drifts beyond tolerance.
