## Overview

The Starrett 91B Tap Wrench is a 9-inch, alloy steel tool designed for precision tapping with a 3/16 to 1/2 inch tap size range. Featuring a tempered gripping surface and a smooth plunger-operated knurled sleeve, it offers superior control and durability. Proudly made in the USA, it’s the trusted choice for professionals and serious DIYers demanding accuracy and reliability in every tap.

## Description

The Starrett 91 Tap Wrench is strong and well proportioned. It is nicely finished and the gripping surface is properly tempered. It will firmly hold square or round shanks. It is plunger operated by knurled sleeve, the spring inside the sleeve causes plunger to back off when pressure is removed. 9" (225mm) Length, 3/16-1/2" (4.7-12.7mm) Tap Size. A tap wrench used in combination with a drill tap is the traditional method to tapping (threading) a hole. This traditional method continues to be a preferred tapping method for when precision tapping is required on prototypes, one-off, post processing, and when minimal material exists around the hole. holes in a hole patterns is too significant to include in a machine program. In essence the tool has a basic "T-Wrench" configuration, which uses handles that extend from the center axis of the tap so that additional torque in the tap can be created. Since a tap requires a specific amount of material at a specific dimension in order to create an effective thread, this manual method can provide excellent feedback to the operator as they progress the tap into the thru-hole.

Review: A thing of beauty..........and functional too, buy once, use forever.
Review: I have not tapped many holes before, but now have a project requiring me to tap nearly 100 holes in extruded aluminum, so buying a quality tap wrench was easily justified. Mine was made in the U.S.A. and did not have the thread gunk that others have mentioned here (the first thing I did was take it apart to check). I loaded up my 5/16-18 tap and got to work. The way this feels in your hand when turning and spinning is fantastic. The handle tightens down well on the tap and doesn't come loose. The monolithic design is really worth the price of the tool in my opinion. No one likes tapping holes, so at least get some satisfaction by using a high quality tool during the process. In my case, I 3D printed a 3 inch long jig/template to affix to the end of my profiles to ensure I'm getting perpendicular taps (see photo). This method is working very well and I don't have to worry about the tap getting out of alignment on the first bite of the aluminum, especially since my extrusions are very long so I have to tap horizontally.

It’s 95% good. Seams a little like it’s a factory second, but near perfect. A little scuffing on the handle.
