Through and blind hole machine tap HOLEX Sturdy version, with straight flutes Application Tapered pipe threads (NPT) to ANSI B1 20 1, for threads

Through and blind hole machine tap HOLEX Sturdy version, with straight flutes. 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 0 A Pre-drill a plain hole, do not use a reamer. Tapping hole 0 B Pre-drill a plain hole then ream it using a 1:16 taper reamer. The taper bore 0 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. Note The GARANT micro lubrication system ensures the optimal and accurate distribution of the cutting oil. This eliminates the need for changeover to 8% emulsion. See No. 130100 size S.
