Tools & Gear Taps & Dies High Performance Coated Taps

HSS-Co Spiral Point (Gun Nose) Taps 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 COATEDTITANIUM NITRIDE COATED Recommended for Plastics and is also acceptable on a wide range of steels. 50% Machining Speed Increase is achievable. METRIC COARSEAngle 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.
