Description

Version:

HOLEX Clever Tap:
Sturdy tap for conventional standard applications. High-quality HSS-E tool material and geometry for steels. Surface: Bronze-coloured tempered thread profile.

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, do not use a reamer.
Tapping hole ⌀ B:

Pre-drill a plain hole 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.
