Goliath No. 8G x 32 UNC Fluteless HSS-Co5 | AIMS Industrial

Applications

• Materials with a minimum elongation of 5% and a tensile strength no greater than 1,000 N/mm2 are suitable for thread forming
• Manufactured from HSS this fluteless tap is designed for use in medium tensile materials and is for hand or general machine use

Specifications

• 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
• 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
• 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
• 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
• It is essential to use a high quality lubricating fluid when using fluteless taps
• IMPORTANT - Fluteless Taps use different tapping drill sizes than standard taps
