Add threads to holes in preparation for installing helical inserts. These taps are made of uncoated high-speed steel and are for use on most metal and plastic. The square shank is compatible with tap wrenches and tap holders for drill presses and milling machines.

Bottoming-chamfer taps cut into the workpiece with just 1-2 chamfered threads. This short chamfer lets them thread holes closer to the bottom than other taps, but they require more torque to start threads.

Application:	Through-Hole Threading, Closed-End Hole Threading

For Use On:	Steel, Iron, Stainless Steel, Aluminum, Brass, Bronze, Copper, Fiberglass, Plastic

Pitch Diameter Tolerance:	0.001" to 0.0015"

REACH:	REACH (EC 1907/2006) (06/14/2023, 235 SVHC) Compliant
