Review on 🔧 Workhorse 5-Piece Certified Hi-Precision Combination Square Set, 12-Inch Rule with 4R Graduations, Cast Head by Aaron Schultz

I'm happy because it's well built. Its central square gauge is on the mark. Hole centering in brass rods and dowels is very important in the manufacture of muzzle loading firearm accessories. Every part of this tool is just perfect for me. I have read several online reviews of this product and I am glad I did and I am glad I bought the product. I would suggest cleaning it with a mildew degreaser/cleaner. I used RCBS. This material is delicate enough to clean such an item. After cleaning it, I lightly oiled it with Starrett Light Tool Oil. I am very, very happy with this tool. I actually bought it for the central square (which is spot on) but other than that it's a great bonus. Protractor is just perfect for me. I have a Swanson combo quad and it's ok for the price I gave it at Lowes. Ideal for checking your circular saw, drill, table saw, etc. This combination is square when perfect.
