Diameter (mm) 5. Bordo HSS Cobalt Metric Fine Spiral Point Tap (3121)
HSS-Co5 (Cobalt) Metric Fine Spiral Point (Gun Nose) machine tap.
Cobalt HSS taps are extremely hard and provide superior performance and increased tool life especially in stainless steel and high tensile steel.
Gun nose taps have straight flutes supplemented by angular cutting faces at the lead.
The design of the cutting portion propels the swarf ahead of the tap leaving the flutes clear for the flow of coolant to the cutting teeth.
Primarily designed for use in through holes, these taps can be used in blind holes provided that there is ample clearance beyond the threaded section to accommodate the swarf.
The advantages of a gun nose tap are the shearing action of the angular cutting faces, which produces a fine finish on the threads and shallower flutes.
This allows a stronger cross section throughout the tap.
Metric Fine taps have a 60° 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).
