7 Piece Metric Coarse Spiral Flute Tap Set
HSS-Co5 (Cobalt) Metric Coarse Spiral Flute machine tap set.
Cobalt HSS taps are extremely hard and provide superior performance and increased tool life especially in stainless steel and high tensile steel.
Spiral Flute taps are designed primarily for machine tapping of blind holes.
They produce the best results 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 Coarse taps have a 60º angle of thread.
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 millimeters).
