## Overview

The Groz 6" Graduated Workshop Steel Square is a premium machinist-grade tool featuring a hardened spring steel blade with precise 6" graduations and an industry-leading 0.00028" squareness tolerance. Designed for professionals who demand accuracy in layout, setup, and inspection, its compact size and durable construction make it an essential companion for woodworking, machining, and fabrication tasks.

## Description

Precision work starts with a square you can trust. The Groz 6" Graduated Workshop Steel Square is built for machinists, toolmakers, fabricators, and serious woodworkers who need a reference square that doubles as a graduated rule for layout and inspection.Inside and outside right angles are held to a squareness tolerance of 0.00028", and both the blade and stock are accurately ground for straightness and parallelism. The blade and stock are made from hardened spring steel so reference edges resist wear and stay true under regular shop use. Graduations etched along the 6" blade let you measure, scribe, and square in one motion instead of reaching for a separate rule.Use it for setting up and checking machinery, verifying carpenter's squares and combination squares, marking joints, and testing faces and edges on stock during fabrication. The compact 6" size fits in an apron pocket or top toolbox drawer, making it a practical companion to the Groz 01142 4" workshop square for benchwork, machine setup, and inspection tasks.

Review: This is a Try Square - It's purpose is to sit on short end (stock) next to your table saw blade so you can adjust saw blade to square. Mine a 6" square blade with imperial markings etched into one side, to measure height of saw blade. There was no choice of cm or in markings. Higher square blade, more accurate square, but consider if the height ordered will clear your table saw blade guards. I have not checked this against Starett/other but relied on reviews, and visibly is accurate.
Review: Great squares - True, good weight and quality

## Features

- PRECISION GRADUATED BLADE - Stop second-guessing layout marks; the 6" blade is etched with precise graduations so you can square, measure, and scribe in a single tool instead of swapping between a rule and a try square.
- CERTIFIED SQUARENESS TO 0.00028" - Inside and outside right angles are held to a 0.00028" squareness tolerance, giving machinists, toolmakers, and inspectors a reference square accurate enough for checking other carpenter's squares and shop fixtures.
- HARDENED SPRING STEEL CONSTRUCTION - Blade and stock are made from hardened spring steel and accurately ground for straightness and parallelism, so the square holds its edge and reference faces under daily shop use.
- PROFESSIONAL LAYOUT AND INSPECTION TOOL - Built for setting up and checking machinery, verifying carpenter's squares, marking joints, and testing faces and edges on stock during fabrication, machining, and woodworking.
- COMPACT 6 INCH SHOP-READY SIZE - The 6" blade length fits in an apron pocket or toolbox drawer and is ideal for benchwork, small parts, machine setup, and tight workspaces where a larger framing square is unwieldy.

### ⭐⭐⭐⭐⭐ Great squares

True, good weight and quality

### ⭐⭐⭐⭐⭐ Just perfect
*by P***O on October 31, 2019*

Felt like I was buying it "sight unseen" since there were no reviews. I wanted a square that would measure from zero on the inside edge, and measure from zero from the base for vertical measurement. I would think that would be a good idea and expected to have no problem. However, the only squares I could find on Amazon that measure that way are the really(!) expensive ones. So I ordered this one hoping for the best and was not disappointed. It's solid and as near as I can tell perfectly square.
