24 x 3mm Left Hand MC Tap Set

About this item:

• 24 x 3mm Left Hand MC Tap Set
• HSS Metric Coarse LEFT HAND Hand and Machine Tap Set.
• 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).
• 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.
• 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.
• Taper Taps have a lead of eight threads and are used as a starting tap in difficult or high precision holes.
