Version:
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.
 
Application:
Tapered pipe threads (NPT) to ANSI B1.20.1, for threads with sealants. See the table for the specified minimum size of the tapping hole.
 
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 (see No. 162650). The taper bore ⌀ can then be checked laterally by reference to the Dmax check dimension (see table). Variant B for drilling the tapping hole offers the best process reliability for the tapping operation.
