M.A. Ford Twister Micro-Tuff Drill 1.85 mm

The M.A. Ford Twister Micro-Tuff Drill 1.85 mm is a precision cutting tool designed for creating small-diameter holes in metal and composite materials. It suits machinists and maintenance technicians who require accurate drilling in confined spaces.

Sustained cutting behaviour

The Micro-Tuff geometry resists wear during continuous drilling cycles, maintaining edge integrity where standard drills may dull quickly. Heat buildup is managed through the flute design, allowing the 1.85 mm diameter to stay on size through repeated use.

Installation and common issues

The straight shank fits standard collets and drill chucks without adapters, so setup is straightforward. Breakage usually occurs if feed pressure is excessive or if the workpiece moves, so rigid clamping and consistent speed are essential.

Questions about this item

How much heat does the 1.85 mm Twister Micro-Tuff Drill generate during extended use?

As a solid micro drill without internal moving parts it produces negligible heat itself; cutting temperature depends on spindle speed, feed rate and workpiece material.

What tool holder or collet is required to run the 305M0185 micro drill?

A precision collet or chuck that accepts a 1.85 mm shank is needed; the holder must provide concentric clamping to keep run-out low.

Can the 1.85 mm Twister Micro-Tuff Drill be used on a legacy drill press with standard run-out?

It will fit mechanically, but typical run-out on older presses may exceed what a micro drill tolerates, reducing hole accuracy and tool life.
