Micro-Tuff Drill for precision work

The M.A. Ford Twister Micro-Tuff Drill is a pneumatic accessory sized at 0.33 mm for fine-hole drilling tasks. It is built for technicians and engineers who need accurate small-diameter results in controlled environments. The tool arrives new and ships directly from the manufacturer.

Suited for micro-drilling.

This drill serves users creating pilot holes, instrumentation ports or delicate component apertures where minimal run-out matters. It is not intended for high-volume production lines, large-diameter work or applications requiring coolant-through capability. Buyers needing wider diameters or indexable inserts should look at a different tool range.

0.33 mm cutting diameter defines the application

The single specification that decides fit is the 0.33 mm diameter, which locks the drill to micro-machining jobs and compatible collet or chuck systems. California Proposition 65 notices apply, stating the product contains chemicals known to cause cancer and birth defects or other reproductive harm.

Questions about this item

How often will the 0.33 mm Twister Micro-Tuff drill need replacing under normal use?

The 0.33 mm Twister Micro-Tuff drill is a consumable cutting tool; replace it when the cutting edges dull or the flute clogs beyond cleaning.

What limits continuous drilling with this 0.33 mm pneumatic accessory?

The primary limit is heat buildup in the micro-diameter flute; sustained high-speed runs without peck cycles will anneal the cobalt substrate.

Does the 305M0033 drill generate noticeable heat or vibration during all-day pneumatic operation?

The 0.33 mm diameter produces minimal vibration, but the small flute area concentrates cutting heat; use coolant mist to manage temperature.
