{"product_id":"starrettcombinationsquare12","title":"Starrett Combination Square","description":"\u003cp\u003eThe Starrett combination square is one of the most versatile and useful marking and measuring tools in the woodworking shop.\n Carefully machined and manufactured in the USA since 1878, Starrett squares are known for their accuracy, reliability, precision\n and long service life. Dead accurate like a high quality engineer's square, and far more versatile and precise than a try square,\n a Starrett combination square has a head made from durable cast iron or hardened steel. The rules (blades) are hardened, tempered\n steel with photo-engraved graduations that will never wear out and have a non-glare satin chrome finish. Often copied, but rarely\n duplicated, a Starrett combination square will be a tool you will rely on year after year for accurate joint layout, checking your\n work for perfect square \u0026amp; 45 degree angles, and for accurately setting up your woodworking machines.\u003c\/p\u003e\n \n\u003ch5\u003eStarrett Combination Square Heads\u003c\/h5\u003e\n\u003cp\u003eThe \u003cb\u003e standard combination square head \u003c\/b\u003e has a 90° face and a 45° face. It is used for check square or 45° on everything from\n table saw blades to jointed edges of boards.It includes a built-in spirit level and a hardened steel steel scribing pin. The\n \u003cb\u003e center head \u003c\/b\u003e is used to find the center of round workpieces (dowels, small table tops, etc.) The \u003cb\u003e protractor head \u003c\/b\u003e\n is used to precisely measure angles.\u003c\/p\u003e\n \n\u003cp\u003eAll three heads come in cast iron with a black wrinkle finish. The standard head and center head are also available in hardened \nsteel with a glossy black finish. Hardened steel heads are typically used by metal workers.\u003c\/p\u003e\n\n\u003cp\u003eThe heart of the combination square is the locking bolt. All three types of head use Starrett's precise, reversible and reliable\n locking bolt. It locks the blade in place with just a few turns and keeps the blade square without slipping through many years of\n service.\u003c\/p\u003e\n \n\u003ch5\u003eStarrett Combination Square Blades\u003c\/h5\u003e\n\u003cp\u003eAll of our Starrett combination squares have hardened steel blades with a satin chrome finish. The satin chrome finish reduces\n glare and makes the rule easier to read.\u003c\/p\u003e\n \n\u003cp\u003eOur inch graduated Starrett combination squares use the # \u003cb\u003e 4R \u003c\/b\u003e inch graduation pattern on their blades. One side of the\n blade has quick reading 64ths \u0026amp; 32nds. The other side of the blade has 16ths and 8ths. The blade can be mounted in the square\n in all four positions so that your preferred scale is in the best position.\u003c\/p\u003e\n \n\u003cp\u003eOur metric-inch graduated Starrett combination squares use the #35 graduation pattern. They have 1\/2mm and 1mm graduations on\n both sides of the blade.\u003c\/p\u003e\n \n\u003ch5\u003eCombination Square Sets\u003c\/h5\u003e\n\u003cp\u003eStandard combination squares come with the blade (rule) and the standard square head.
