TB42EF3 10 x 1.5mm Spiral Flute TIN HSS-Co5 Tap - Goliath HSS-Co5 (Cobalt) Titanium Nitride Coated (TiN) High Performance Spiral Flute Machine Tap. 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. 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.
