- HSS Bright Finish Metric Coarse Hand and Machine Tap Set (T, I, B).
- 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.
- Metric Coarse angle of 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.
- 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 are specified by a simple numerical value (most commonly measured in millimetres).
- Taper Taps have a lead of eight threads and are used as a starting tap in difficult or high precision holes.
- 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.
- Bottoming Taps have a lead of two threads and are used to ensure minimum thread run-out when tapping to the bottom of a blind hole.
- Bottoming Taps are typically preceded by the use of a Taper or Intermediate Tap.
- Manufactured from HSS this general purpose tap is designed for use in medium tensile materials and is for hand or general machine use
