Description

This Holex Through and Blind Hole German Machine Tap is an uncoated, sturdy through and blind hole machine tap with straight flutes.

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

Recommendation:

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. Variant B for drilling the tapping hole offers the best process reliability for the tapping operation.
