A short description on tap wrenches

A tap wrench is a clamping tool for cutting internal threads by hand. Adjustable tap wrenches have tap wrenches in their clamps. But basically any tool with a square shape can be clamped. The most commonly used tools are hand taps, reamers and screw extractors. In layman's terms, adjustable tap wrenches have a variety of names and designations. Very often, it is called a reversible tap or tap holder. However, the correct name according to DIN 1814 is: adjustable tap wrench.

The most important quality criteria for evaluating tap wrenches are: the reamer iron body and the machined material in the geometry of the handle, jaws and reamer iron body.

What is the difference?

As the name implies, the main difference between the two designs is the material of the base body. The main body can be made from steel in the investment casting process or from zinc die casting in the hot chamber die casting process.

Why do I need a centering eye?

The centering eye is a product innovation of GSRIC and is basically a leveling device embedded in the body of the tool. The level helps to calibrate the all-steel tap wrench plumb and true.

This product innovation is unique due to the high quality craftsmanship of the body geometry, handle and adjustable jaws. As a result, higher torque is achieved. The integrated centering eye also ensures more precise alignment and better thread cutting. You no longer need to align angles. An advantage that leads to fewer errors, especially for larger and more expensive tap diameters. Skewed threads can lead to tool breakage and workpiece breakage.

Place the tap wrench, including the tap, on the core hole. When tapping, you can cut 2 - 3 turns until the tap is held/gripped. While continuing to rotate, center the vial bubble to align. Now complete the cutting thread.
