{"title":"Combination Squares","description":"\u003cp\u003eCombination squares are the most versatile single layout and measurement tool in any Australian workshop. A combination square pairs a graduated steel rule (typically 150mm or 300mm) with sliding heads that lock anywhere along the rule with a knurled thumbscrew. One tool delivers four primary functions: 90° squareness check, 45° mitre marking, depth gauge, and — with the optional protractor and centre finder heads — any-angle setting and centre marking on round stock.\u003c\/p\u003e\n\n\u003cp\u003eAIMS stocks combination squares from \u003cstrong\u003eDasqua\u003c\/strong\u003e (cast iron premium tier) and \u003cstrong\u003eMaxigear\u003c\/strong\u003e (workshop default), in 150mm and 300mm sizes, as complete four-piece sets and individual replacement heads.\u003c\/p\u003e\n\n\u003ch2\u003eWhat is a combination square — the four components\u003c\/h2\u003e\n\u003cp\u003eA complete combination square set is a four-piece kit. Each component slides onto the same graduated rule and locks in any position:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare head\u003c\/strong\u003e — provides reference 90° and 45° faces for marking out, squareness checking, height transfer and step measurement. Includes a spirit level vial for levelling and a hardened scriber stored in the head for marking lines.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentre finder head\u003c\/strong\u003e (centre square) — V-block geometry locates the exact centre of a round bar, shaft or cylindrical workpiece. Critical for accurate centre punching before drilling concentric holes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProtractor head\u003c\/strong\u003e — graduated 0–180° (often with reverse scale) for setting and reading any angle. Used for mitre cuts, angled layout, dimensional checks against drawings.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGraduated rule\u003c\/strong\u003e — 300mm (or 150mm) hardened tool steel or stainless steel, with metric and imperial graduations etched on both edges. Doubles as a steel rule when removed from the heads.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eCombination square vs engineers square — which do you need?\u003c\/h2\u003e\n\u003cp\u003eAn \u003cstrong\u003eengineers square\u003c\/strong\u003e is a fixed 90° try square — single function, highest squareness accuracy (DIN 875 Grades 00, 0, 1, 2), and the reference tool against which other squares are checked. A \u003cstrong\u003ecombination square\u003c\/strong\u003e is variable and multi-function: 90°, 45°, any angle (with the protractor head), centre finding (with the centre head), depth gauge and rule. The trade-off is squareness accuracy — a precision engineers square holds tighter tolerance than the locked head of a combination square.\u003c\/p\u003e\n\u003cp\u003eUse an engineers square when DIN 875 Grade 0 or Grade 1 squareness reference is required (inspection, setup work, milling vice alignment). Use a combination square for general layout, marking out, field work, mitre setting, centre finding and any-angle work. Most workshops want both.\u003c\/p\u003e\n\u003cp\u003eFor the full breakdown — DIN 875 accuracy grades, reversal method testing, sizes by trade, and selection by application — see the \u003ca href=\"\/blogs\/product-guides\/engineers-square-combination-square-steel-rule-guide\"\u003eEngineers Square, Combination Square \u0026amp; Workshop Steel Rule Guide\u003c\/a\u003e.\u003c\/p\u003e\n\n\u003ch2\u003e300mm vs 150mm combination squares\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003e300mm (12\") combination squares\u003c\/strong\u003e are the workshop default.
