RUKO SCE-DIN22568-HSS-60°-1-1/4 HSS-G Parallel Pipe Thread Tap, 1 1/4 Inch, DIN 22568

This RUKO pipe thread tap cuts G 1 1/4 parallel pipe threads to DIN 22568. Unlike tapered pipe taps, the parallel thread form suits mechanical joints where the thread itself does not seal. The HSS-G ground flutes deliver clean threads in steel, cast iron, non-ferrous metals and plastics.

Highlights

• Thread type: G (BSP-P) parallel pipe thread
• Nominal size: 1 1/4 inch, 11 TPI, 55° Whitworth form
• Right-hand cutting, 4 flutes
• Bright finish, HSS-G ground

In daily use

The 140 mm overall length and 50 mm thread length suit through holes and blind holes with sufficient clearance. The 28 mm shank and 22 mm square drive fit standard tap wrenches. A core hole of 41.25 mm is recommended for the 1 1/4 inch thread.
