Micro-Tuff Drill 0.37 mm

The M.A. Ford 305M0037 Twister Micro-Tuff Drill is a precision pneumatic accessory designed for creating 0.37 mm holes. It targets machinists and technicians who need reliable small-diameter drilling capability in a workshop environment.

Build integration and workflow

This drill fits directly into compatible pneumatic tooling systems without additional adapters. Its Micro-Tuff construction resists breakage during high-speed operation, freeing the operator from frequent bit changes and reducing downtime on intricate jobs.

Upgrade path and value

The drill replaces standard micro drills that wear quickly or fracture under load. The jump is worth it when consistent hole quality at 0.37 mm is critical and the cost of scrap or rework outweighs the price difference.

Questions about this item

How small a hole can the 0.37 mm Twister Micro-Tuff Drill produce before the bit snaps under sustained pressure?

The 0.37 mm diameter is the practical limit; applying steady feed pressure beyond this size risks breaking the micro-drill.

Does the drill generate noticeable heat or vibration during extended pneumatic operation?

The micro-drill runs cool with minimal vibration when used at recommended pneumatic speeds and feed rates.

What pneumatic tool or collet is required to hold the 0.37 mm shank?

A precision collet or chuck capable of gripping a 0.37 mm shank is needed; standard 1/4 in. or 3 mm collets will not work.
