Tools & Gear Taps & Dies HSS Hand and Machine Taps

• 3/8" x 18 NPSF Taper HSS Tap - Goliath
• HSS Bright Finish NPSF Hand and Machine Taper 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.
• National Pipe Straight Fuel (Dryseal) is used for internal threads and an NPTF external thread can be screwed into it to provide both a satisfactory mechanical connection and hydraulic seal.
• A combination of a parallel and tapered thread would not appear to be ideal but it is widely used.
• Many quick disconnect couplers for example have the NPSF thread and are recommended by the manufacturer for use with NPT and NPTF.
• Taper Taps have a lead of eight threads and are used as a starting tap in difficult or high precision holes.
• Manufactured from HSS this general purpose tap is designed for use in medium tensile materials and is for hand or general machine use.
