Product Description
Garant NPT HSS-E TiAlN Coated Machine Tap
This Garant Through and Blind Hole German Machine Tap, TiAlN coated, features a special TiAlN coating for long tool life due to interrupted guide thread, reduced tapping torque and improved distribution of lubricant. This can be used with emulsion where fat content is a minimum of 8%.
Applications:
Tapered pipe threads (NPT) to ANSI B1.20.1, for threads with sealants.
Recommendation:
Tapping hole ⌀ A:
Pre-drill a plain hole without using a reamer.
Tapping hole ⌀ B:
Pre-drill a plain hole and then ream it using a 1:16 taper reamer. The taper bore ⌀ can then be checked laterally by reference to the Dmax check dimension. Variant B for drilling the tapping hole offers the best process reliability for the tapping operation.
