About 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.

About UNC Unified National Coarse

• This 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 the internal thread.
• It is also used on quick assembly or disassembly or if corrosion or slight damage is possible.

About Intermediate Taps

• 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.

About Drill Bit Surface Treatment

• Bright Finish Jobber Drills have no surface treatment and are supplied in the as-ground condition.
• These tools are suitable for general purpose use, particularly for non-ferrous applications.
