Product identity

The M.A. Ford Twister Micro-Tuff Drill 305M0240AM-1 is a 2.40 mm cutting tool built for precision drilling tasks. It suits machinists and technicians who need reliable performance in small-diameter applications. This new accessory carries the manufacturer’s quality mark.

Build integration

The drill fits directly into compatible collets or chucks without additional adapters. Its micro-scale shank allows access to tight work areas where larger tools cannot reach. Users gain flexibility when producing fine holes in a range of materials.

Thermals noise power

Normal operation generates typical cutting heat that standard coolant or air flow manages effectively. Noise levels remain consistent with similar micro-drills running at recommended speeds. Power draw depends entirely on the host machine and feed rates selected.

Questions about this item

How quickly does the 2.40 mm Twister Micro-Tuff drill reach its wear limit under continuous drilling?

The 2.40 mm diameter determines chip load and edge life; sustained high feed rates on hardened steel will dull the cutting lips first, so reduce pressure and use coolant to extend usable length.

What heat and noise levels should I expect when running this 305 series drill all day?

The solid-carbide 2.40 mm bit runs hot at high RPM; expect noticeable whine and rapid temperature rise at the shank — use peck cycles and flood coolant to manage both.

Which tool holder or collet must I already own to mount the 2.40 mm shank?

You need a precision ER collet or shrink-fit holder bored for 2.40 mm; standard 1/8 inch or 3 mm collets will not grip the metric shank securely.
