When you are tapping smaller holes, a double-handled wrench, either commercial or home-built, turns your tap more easily and helps to keep it perpendicular. When you are using large taps — one inch and up — this industrial strength tap wrench is an absolute necessity. You simply won't be able to get the control or torque you need without it. This Steel Tap Wrench will accept all our taps, from 1/2" to 1 1/2".
