Review: Great small combo square - I recently purchased the Johnson Level & Tool 406EM Professional Inch/Metric Combination Square, and I must say, it has far exceeded my expectations in terms of quality, value, and usability. I have a number of larger squares but needed something smaller for a project. Given its surprisingly affordable price, I was initially skeptical about its performance and durability. However, after using it extensively in various projects, I'm thoroughly impressed. It's a tool that not only meets but exceeds expectations, and I wholeheartedly recommend it to anyone in the market for a reliable combination square. Review: Great buy!! - Good med. Size square. Good Quality! Strong, and comes with a scribe screwed in on the bottom. I been using it daily for work for over 5 yrs and it's still in great condition. As a press break operator making parts for aerospace I definitely recommend this square! ## Features - COMBO SQUARE: This Johnson combination square was designed with maximum accuracy in mind - its square head is CNC machined for greater accuracy. - STAINLESS BLADE: This combination square has a stainless steel blade with stamped graduations in 1/8", 1/16", and 1/32"; as well as millimeter graduations that are permanently imprinted so they will never fade or degrade - ACCURATE MEASUREMENTS: Auto-Lock blade assembly ensures precise alignment for optimal tool performance - APPLICATIONS: Ideal machinist's square; straightedge; adjustable try square; miter square; marking gauge; and depth gauge - PRODUCT SPECIFICATIONS: Accurately measure 45Β° and 90Β°, mark miter cuts and find depth as well as simple distance measurements.
