36475 Exposed Ratchet Threader Kit

Threader Kit, Exposed Ratchet, Diameter: 1/2" (3mm) - 2" (50mm). NPT Threads

Rated 5 out of 5 by butchalvarez from The 12-R, an industry standard My reveiw is about the legendary 12-R manual threading set. These heads do a perfect threading job consistently, each and every time. You can use these heads with the manual ratchet or for speed and ease, the electric model 700 power drive is without equal (but that's another reveiw).
