Straight groove wire tapping for light alloys is specifically designed for materials with high viscosity properties; Such as aluminum, sub lead alloy and other pressure cast light alloy for tooth tapping processing. Due to the tendency of the threads of this type of material to shrink and become smaller (shrinkage holes) after tooth tapping processing, the precision of LA-O products is designed to be increased, and the surface is treated with nitriding to match the properties of this type of material.

·Screw tapping accuracy: YAMAWA P grade

·Number of teeth in the cutting edge: LA-O 1.5 teeth/5 teeth AL-SP 1.5 teeth/2.5 teeth
·Surface treatment: chemical treatment
·Suitable for cutting materials: die cast alloys such as aluminum, zinc, magnesium, etc
