Bordo 3-12mm 14 Pce MC Intermediate Tap & Drill Set

Description

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.
