Twister Micro-Tuff Drill No 49

The M.A. Ford Twister Micro-Tuff Drill No 49 is a precision cutting tool designed for machining operations that require small-diameter holemaking. It serves machinists and maintenance technicians who need reliable performance in demanding materials.

Sustained-load behaviour

The drill's Micro-Tuff construction supports consistent chip evacuation and edge retention during extended drilling cycles. This reduces the risk of tool deflection and premature wear when operating at production feed rates.

Upgrade path

It replaces general-purpose drills that fracture or walk in tough alloys and hardened steels. The step is justified when hole accuracy and tool life outweigh the cost of standard high-speed steel alternatives.

Questions about this item

How much heat does the No 49 Twister Micro-Tuff Drill generate during continuous drilling?

The drill is a solid carbide cutting tool without a motor, so it produces only the frictional heat normal for high-speed machining; the machine spindle and coolant system manage temperature.

What shank size or tool holder is required to run the 30507300 drill in my machine?

The drill uses a standard straight shank sized to match its No 49 diameter, fitting common ER collets, drill chucks or hydraulic holders that accept that shank dimension.

Will the 30507300 drill work reliably in an older CNC mill with lower spindle speed and run-out?

The solid carbide construction and Twister geometry tolerate moderate run-out and lower speeds better than many micro drills, though optimal life still needs accurate spindle concentricity.
