Description

10 x 1.25mm MF Spiral Flute HSS-Co5 Tap – Goliath
HSS-Co (Cobalt) Bright Finish Metric Fine Spiral Flute Machine Tap.
HSS-Co Spiral Flute Taps.
Spiral Flute taps are designed primarily for machine tapping of blind holes.
They are used to the best advantage in materials that produce long continuous chips.
The right hand spiral forces the swarf out of the hole and prevents the chips from clogging at the bottom of the hole or in the flutes, which could cause tap breakage or spoiled threads.
Metric Fine 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).
Manufactured from HSS-Co5.
