Selecting the right option
Metric fine tap sets suit precision applications — confirm MF pitch before ordering. MF threads are not interchangeable with metric coarse — verify the thread specification in your assembly. Sets are typically supplied with taper, second, and plug taps for hand threading.

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.
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.
