This Garant German Master Tap NPT Machine Tap HSS-E-PM AlTiX is a German engineered NPT Machine Tap, available in multiple sizes, that is a universal tap, designed for use in a wide spectrum of materials with high process reliability for tapered pipe threads (NPT) to ANSI B1.20.1, for threads with sealants.

Specifications/Information:

Universal taps, designed for use in a wide spectrum of materials with high process reliability
HSS-E-PM tool material for maximum wear resistance
Reduced coefficient of friction due to the new high-performance coating
Special geometry for optimum chip evacuation

Applications:
Tapered pipe threads (NPT) to ANSI B1.20.1, for threads with sealants. 

Recommendations:
Tapping hole diameter A:
Pre-drill a plain hole without using a reamer.
Tapping hole diameter B:
Pre-drill a plain hole and then ream it using a 1:16 taper reamer. The taper bore diameter can then be checked laterally by reference to the Dmax check dimension (see table below). Variant B for drilling the tapping hole offers the best process reliability for the tapping operation.
