No 10G x 24 UNC Fluteless HSS-Co5 Tap - Goliath

About this item:

• No 10G x 24 UNC Fluteless HSS-Co5 Tap - Goliath
• HSS-Co (Cobalt) Bright Finish UNC Fluteless Machine Tap.
• HSS Fluteless (Roll Form) Taps.
• Fluteless taps are also referred to as "Roll Form" or "Thread Flow" taps.
• Unlike standard taps, fluteless taps create internal threads by pressure deformation, rather than by material removal.
• As a result, no chips are formed as no material is removed.
• The thread is formed by the tap in the ductile material creating threads that have a smoother surface and greater tensile strength under dynamic stress than cut threads.
• It is essential to use a high quality lubricating fluid when using fluteless taps.
• Materials with a minimum elongation of 5% and a tensile strength no greater than 1,000 N/mm2 are suitable for thread forming.
• Unified National Coarse thread form was introduced in 1948 as an attempt to standardise thread forms in the USA, Canada and the UK.
• The thread profile of UNC is the same as for metric threads and is described in the JIS B0206 standard.
• The thread is described by its major diameter and the number of threads per inch of length (TPI).
• This thread series is commonly used in the mass production of bolts, screws and nuts.
• It is used for threading into lower tensile strength materials (bronze, brass, aluminium and plastics) to obtain the best resistance to stripping of the internal thread.
• It is also used on quick assembly or disassembly or if corrosion or slight damage is possible.
• Manufactured from HSS this fluteless tap is designed for use in medium tensile materials and is for hand or general machine use.
• IMPORTANT - Fluteless Taps use different tapping drill sizes than standard taps.
