Chips discharge ●The special flute shape offers the following performance effects; ⑧ 1. Prevents chipping of the complete threads.2. Reduces the tapping torque and frictional Troubleshooting resistance. 3. Creates a smooth discharge of chips. Moving the identification markings to the square end of the tap generates a roundness with higher precision, a better surface ⑨ finish on the taps shank diameter and improves the accuracy of the tap. Minute burrs can occur during marking, even with laser engraving, therefore moving the identification markings to the square improves the overall quality and performance of the tap. ⑩ The AU+SP is applicable to a wide range of work materials. It utilizes a flute shape that can maximize the features of the coating (wear resistance, heat resistance, resistance to welding) and can handle a wide range of work materials. It is also ideal for water soluble cutting fluids. ⑪ JIS ①-83 BLFShape
