Goliath MF Straight Flute Tap - Bottoming HSS Bright

• Left Hand HSS Bright Finish Metric Fine Hand and Machine Bottoming Tap.
• 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.
• The metric Fine 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 the external thread and pitch are specified by a simple numerical value (most commonly measured in millimetres).
• 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.
