We are pleased to announce the expansion of our A Brand A-SFT series with the introduction of the A-SFT-LH. OSG’s A-Tap is an all-purpose tap series designed to simplify tool management and to excel in a wide variety of materials and applications. Achieving trouble-free chip evacuation with a spiral tap in blind holes is particularly challenging and is a main cause of headaches for many manufacturers. To resolve this problem and to improve the ejection of chips, OSG’s A-Tap A-SFT has adopted a variable helix flute design, which encourages stable chip evacuation. The helix angle changes from the chamfer, where chips are formed, to the flutes, where chips are evacuated. This unique geometry enables greater chip control that can help produce tightly compacted chips for easy ejection from the hole. 

The following list numbers are associated with the expansion:
