Goliath MF Straight Flute Tap Set HSS Bright

• HSS Bright Finish Metric Fine 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 Fine 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.
• A larger root radius and lower thread height enable easy screw thread processing and increase thread screw strength. The major diameter of the 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.
