Twister Micro-Tuff Drill 0.86 mm

This new M.A. Ford Twister Micro-Tuff drill bit is sized at 0.86 mm for fine drilling tasks. It belongs to the Power & Pneumatic Accessories category and is supplied as a pneumatic accessory. The part number is 305M0086.

Build quality and shank fit

The drill carries the Micro-Tuff designation from M.A. Ford, indicating a construction intended for precision work. Its shank dimensions suit standard collets or chucks used with pneumatic handpieces, so it installs without adapters. Daily use involves securing the bit, running the tool, and replacing the bit when wear appears.

Practical limits of the 0.86 mm diameter

At 0.86 mm the drill removes very little material per pass, so feed rates must stay low to avoid breakage. The small diameter also limits hole depth to what the flute length can clear. California Proposition 65 warnings note that the product contains chemicals known to cause cancer and birth defects or other reproductive harm.

Questions about this item

What shank standard does the 0.86 mm Twister Micro-Tuff drill use, and what chuck capacity does that limit it to?

The drill has a straight 0.86 mm shank, so it fits any drill chuck or collet that closes down to 0.86 mm or smaller.

What physical clearance does the 305M0086 need to fit inside a machine or fixture?

The tool is a 0.86 mm diameter micro drill; allow at least that diameter plus the flute length for hole depth and chip evacuation.

How is the 0.86 mm Twister Micro-Tuff drill installed, and what step do users often miss?

Insert the straight shank fully into a clean, correctly sized collet or chuck and tighten evenly; the common mistake is clamping on the flutes instead of the shank.
