GBP 57 NPT C 60° HSS-E- ANSI h9 PM Standard B1.20.1 3 1:16 40° GARANT Master Tap machine tap for tapered NPT pipe threads 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: 13 8105 Pre-drill a plain hole without using a reamer. Tapping hole ⌀ B: L 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.

Application: For use as machine tap or for cleaning existing threads by hand. Tapered Whitworth pipe thread (BSPT) to ISO 7/1 and BS21, for joints with sealant in the thread. See the table for the specified minimum size of the tapping hole. Recommendation: Tapping hole ⌀ A: 13 8120 Pre-drill a plain hole without using a reamer. Variant A can be used if there is no risk of sealing problems. Tapping hole ⌀ B: L 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 ØD drilling the tapping hole offers the best process reliability for the tapping operation and at the same time Ø DS ensures the most reliable seal in the thread.
