Greenfield Threading pneumatic accessory 301193 #5-44 UNF Bottoming 3 Flutes

Threading tap for #5-44 UNF threads

This Greenfield Threading accessory is a straight-flute hand tap designed to cut internal #5-44 UNF threads. It suits mechanics and fabricators who need a bottoming tap for through-holes or blind holes where thread depth is limited. The high-speed steel body with TiN coating resists wear during repetitive hand-tapping tasks. Right-hand cutting direction matches standard fastener conventions.

Capacity and headroom for #5-44 UNF tapping

The tap cuts a 75 percent thread using a 2.60 mm drill size and conforms to H2 thread limits for a 2B class of fit. Its .63 in thread length defines the maximum depth it can reliably cut in a single pass. It runs out when the workpiece material exceeds the tap's hardness range or when hole depth surpasses the .63 in thread length without chip clearance. The 1.94 in overall length limits reach in deep cavities.

Thermals, noise and power draw in hand use

As a manual tool, the tap generates heat only through friction at the cutting edges during rotation. TiN coating reduces friction, limiting temperature rise in the workpiece and tap. Noise is restricted to the sound of the tap turning in the handle and chip formation. Power draw depends entirely on the operator's applied torque and speed. No external power source or cooling system is involved.
