The OSG 2842901 is a 1/2"-20 UNF oversized spiral point tap with H11 tolerance for 2B class fit. It has 3 flutes and a plug chamfer. The oversized design compensates for coating or post-treatment buildup. It is made from premium high-speed steel for durability.

How to select the correct OSG tap for UNF threads?
