For Accurate Thread Cutting, Reaming & Drilling
Precision-made tap wrenches help you apply the exact amount of leverage needed to cut straight, true threads for scope bases, finish ream chambers, and drill or deburr holes. Easy-to-grasp, knurled collet tightens securely around the tap, reamer, or drill bit to prevent slipping. Built from forged steel, then hardened for added strength and durability. #174 features a combined one-piece body and handle that produce an extra-long lever for maximum torque when turning. Elliptical jaws hold round- or square-shank tools up to ¼" diameter. #93 features a removable T-Handle and four-corner jaws for a rock-solid hold on square-shank tools. Centered pilot hole on body allows hand-turning in drill presses, mills, and lathes.
