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.
The metric Coarse angle of the thread is 60 degrees.
The crest is flat and the thread has clearance at the root allowing external thread and internal thread to engage well.
A larger root radius and lower thread height enable easy screw thread processing and increase thread screw strength.
The major diameter of external thread and pitch is specified by a simple numerical value (most commonly measured in millimetres).
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.
