M.A. Ford 305M0018 Twister Micro-Tuff Drill 0.18mm pneumatic accessory

Micro drill for precision pneumatic work

The M.A. Ford 305M0018 Twister Micro-Tuff Drill is a 0.18 mm pneumatic accessory built for high-speed micro-drilling in tight tolerances. It suits toolmakers, aerospace technicians and jewellers who need reliable hole-making in hardened alloys and composites. The solid-carbide construction resists deflection at the extreme speeds required for such a small diameter.

Direct collet fit reduces runout risk

The shank seats straight into a precision collet or micro-chuck, so no adapter sleeve is needed. Most problems arise when the air supply lacks inline filtration and lubrication; contaminated air wears the flute edges in seconds. Excess feed pressure also snaps the web instantly, so a regulated low-pressure line is essential.

Handles micro holes in tough alloys

At 0.18 mm the drill comfortably produces clean holes in tool steels, titanium and nickel-based super-alloys up to a few diameters deep. Beyond that depth, chip evacuation becomes the limiting factor and peck cycles are mandatory. The design offers no internal coolant passage, so external mist or flood coolant must manage heat in prolonged cuts.
