About this item:

• 3-12mm 14 Pce MC Intermediate Tap & Drill Set
• 3-12mm HSS Metric Coarse Intermediate Hand and Machine Tap set with HSS Tapping Drills.
• 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).
• 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.
• Manufactured from HSS this general purpose tap is designed for use in medium tensile materials and is for hand or general machine use.
