The OSG spiral flute tap 0143608 is designed for threading blind holes in steel and stainless steel. Its V coated powdered metal construction and bottoming chamfer allow it to cut threads close to the bottom of the hole, making it ideal for automotive, aerospace, and general manufacturing applications.

This OSG tap has a 1/2-20 UNF thread size, H5 / 2B-3B tolerance, 3 flutes, and a bottoming chamfer. It is made from V coated powdered metal, part number 0143608. The spiral flute design efficiently evacuates chips upward, preventing clogging in blind-hole threading operations.
