Precision micro drill for fine-hole work

The M.A. Ford Twister Micro-Tuff Drill is a 0.50 mm cutting tool designed for precise drilling in metals and composites. It suits machinists, engineers and hobbyists who need consistent small-diameter holes without wandering.

Solid-carbide construction for rigidity

The solid carbide body resists deflection at high spindle speeds, so the drill stays on centre in handheld or CNC use. A standard cylindrical shank fits common collets and chucks, allowing quick tool changes without specialised holders.

Ready to use with regulatory notice

The drill ships individually packaged and protected for immediate use in the workshop. California Proposition 65 warnings apply because the product contains substances listed for cancer and reproductive-harm risks.

Questions about this item

What chuck size does the 0.50 mm drill shank require?

The 0.50 mm shank fits any standard drill chuck that closes down to half a millimetre, typically a precision keyless or collet-type chuck on a rotary tool or micro-drill press.

How much clearance does the Micro-Tuff drill body need in a fixture?

The drill body is only slightly larger than the 0.50 mm cutting diameter, so the fixture hole or guide bush must allow a few tenths of a millimetre radial clearance for smooth entry and chip evacuation.

Which step do users often skip when installing this micro drill in a collet?

Users frequently forget to clean the collet bore and the drill shank with solvent before clamping; any residue causes run-out that snaps the 0.50 mm tool at the first plunge.
