OSG 1"-8 UNC Spiral-Point Extension Tap

The OSG extension tap 1"-8 UNC is used for threading blind or through holes in multiple materials, including steel, stainless steel, and cast iron. Its extended length reaches deep or recessed areas, while the spiral-point design pushes chips forward for efficient chip evacuation. The V-coated powdered metal construction provides wear resistance for production threading.

The OSG extension tap MPN 1653505708 has a 1"-8 UNC thread size, H6 tolerance, 3 flutes, and a plug chamfer. It is made of V-coated powdered metal for durability. The spiral-point design is suitable for through-hole threading. These specs ensure precise thread formation in demanding industrial applications.
