Micro-Tuff drill for 0.93 mm holes

The M.A. Ford Twister Micro-Tuff drill creates precise 0.93 mm holes in a variety of materials. It is designed for technicians and engineers who require accurate small-diameter drilling in professional workshops.

Replaces worn or undersized micro drills

This drill replaces dull or broken micro drills when hole quality declines or when a specific 0.93 mm diameter is required. The upgrade is worth it when existing tooling cannot hold tolerance or produces rough finishes on critical features.

Check shank fit and material compatibility

Verify that your tool holder or collet accepts the drill shank before ordering. Confirm the workpiece material is suitable for the drill geometry and review the Proposition 65 notice regarding chemical exposure.

Questions about this item

What size collet or chuck does the 0.93 mm Twister Micro-Tuff Drill require?

The 0.93 mm drill shank fits a 0.93 mm collet or a precision chuck that closes fully to that diameter.

How do I install the 305M0093 drill without snapping the 0.93 mm flute?

Clamp the shank only, use low feed pressure, and start the spindle before contact — forcing the tip first is the common error.

When should I replace the 0.93 mm Twister Micro-Tuff Drill?

Replace it when the cutting lips show rounding, chipping, or when hole diameter exceeds tolerance for the 0.93 mm size.
