Cleveland C59361 Thread Forming Tap 1/2"-13 Plug Bright pneumatic accessory

Cleveland C59361 Thread Forming Tap

The Cleveland C59361 is a high-speed steel thread forming tap designed to create internal threads in ductile materials without producing chips. It suits maintenance technicians and machinists who need reliable thread formation in through-hole or blind-hole applications using pneumatic or hand-tapping equipment.

1/2"-13 UNC capacity with H8 limits

This tap cuts a 1/2"-13 UNC thread with a 75 percent thread drill size of 11.70 mm and a thread length of .94 in. The H8 thread limit targets a 2B-3B class of fit, providing appropriate tolerance for general fastening; it is not suited for high-precision aerospace fits or materials that resist cold forming.

Bright high-speed steel with plug chamfer

The uncoated bright finish resists galling in aluminium, mild steel and copper alloys while allowing easy visual inspection of cutting edges. A plug chamfer with 0 flutes starts threads smoothly in existing holes, and the 3.38 in overall length fits standard tap holders; the tool lacks flute space for chip evacuation, so it cannot be used as a cutting tap in brittle or hardened materials.
