Micro-Tuff Drill 0.68 mm

The M.A. Ford Twister Micro-Tuff Drill is a pneumatic accessory built for precision drilling tasks. Its 0.68 mm diameter suits fine-hole work in professional workshops and maintenance environments. The tool arrives new and ready for immediate use with compatible pneumatic systems.

Sustained cutting performance

The Micro-Tuff geometry is designed to maintain edge integrity during extended drilling cycles rather than only in short bursts. Heat dispersion through the flute design helps preserve hardness when the drill runs continuously in tough materials. Operators can expect consistent hole quality over long production runs without frequent tool changes.

Solid carbide construction

The solid carbide body resists deflection and wear better than conventional steel drills in the same size class. A standard shank fits common collets and chucks so setup is straightforward on existing equipment. The 305M0068 part number simplifies reordering and inventory tracking for maintenance teams.

Questions about this item

How much heat does the 0.68 mm Twister Micro-Tuff Drill generate during extended pneumatic use?

As a solid-carbide micro drill, it produces minimal heat when fed correctly through a pneumatic spindle; use peck cycles and coolant to manage temperature in deep holes.

What pneumatic tooling is required to run the 305M0068 0.68 mm drill?

You need a precision pneumatic spindle or micro air motor with a collet or chuck that accepts 0.68 mm shanks, plus clean, regulated compressed air.

Will the 0.68 mm Twister Micro-Tuff Drill work in my older pneumatic micro-drilling setup?

Yes, provided the older unit holds 0.68 mm shanks concentrically and delivers steady air pressure; check collet condition before use.
