Garant NPT HSS-E-PM TiAlN Coated Machine Tap
This Garant Through and Blind Hole Premium Machine Tap, HSS-E-PM TiAlN, is made for the highest performance demands for a machine tap, including for use with emulsion where fat content is a minimum of 8%.
Tapered pipe threads (NPT) to ANSI B1.20.1, for threads with sealants.
For TOOLOX and HARDOX materials, we recommend deviating from the DIN data by drilling the tapping hole âŒ€ 0.05 to 0.3 mm larger.
Tapping hole âŒ€ A:
Pre-drill a plain hole without using a reamer.
Tapping hole âŒ€ B:
Pre-drill a plain hole and then ream it using a 1:16 taper reamer. The taper bore âŒ€ 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.
