（Number of holes tapped) Product Features BLF（Special shape of threaded part) + Significant improvements in chip discharge performance from a unique flute shape.

• The AU+SP tap has a special shape that has the first few threads at full size and reduces the remainder to half of the screw Chips discharge thread height.
• The special flute shape offers the following performance effects;

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

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.

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.
