Tools & Gear Taps & Dies HSS Hand and Machine Taps

HSS Straight Flute Short Machine and Hand Taps These general purpose taps are ideal for creating new threads in a wide variety of materials. 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. BRASS (BSB)BRITISH STANDARD BRASS Brass tubing has a uniform wall thickness - irrespective of the tube diameter - therefore any thread cut on - or in - it needs to have the same depth - so 26 TPI is standard on all BSB diameters. BSB is often confused with BS Cycle thread - the difference being that brass thread has an angle of 55 deg; whereas Cycle is 60 deg;. INTERMEDIATE TAPS have a lead of four threads and are used in most general purpose applications to cut a thread true to a pre-drilled pilot hole. Manufactured from HSS this general purpose tap is designed for use in medium tensile materials and is for hand or general machine use.
