Tools & Gear Taps & Dies HSS Pipe Taps and Reamers

• 1/8" x 27 NPTF Bottoming HSS Tap - Goliath
• HSS Bright Finish NPTF Hand and Machine Bottoming Tap.
• Pipe taps are much shorter than a similar size of regular hand tap, but the design features are the same.
• Goliath HSS taps provide a high hardness to toughness ratio, compressive and tensile strength, good abrasion resistance and resistance to micro-chipping, ensuring a long tool life.
• Tapered Pipe Taps are used for tapered threading by hand or machine.
• National Pipe Taper Fuel (DRYSEAL TAPER) is a semi-compatible variant of NPT, designed to provide a more leak free seal without the use of teflon tape or other sealant compound.
• NPTF threads are the same basic shape but with crest and root heights adjusted for an interference fit, eliminating the spiral leakage path.
• Bottoming Taps have a lead of two threads and are used to ensure minimum thread run-out when tapping to the bottom of a blind hole.
• Manufactured from HSS this general purpose tap is designed for use in medium tensile materials and is for hand or general machine use.
