Tools & Gear Taps & Dies High Performance Coated Taps

• 4 x 0.7mm Spiral Point TIN HSS-Co5 Tap - Goliath
• HSS-Co5 (Cobalt) Titanium Nitride Coated (TiN) High Performance Spiral Point Machine Tap.
• Spiral point taps, also known as "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.
• TiN Coated taps are recommended for use in Plastics and are also acceptable for a wide range of steels.
• 50% Machining Speed Increase is achievable.
• Metric Coarse angle of thread is 60°.
• 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).
