Material and Functions: Carpenter's square is made of premium aluminum alloy, high hardness, high toughness, wear-resistant, anti-oxidation and durable. for three-dimensional marking - measurement and transfer of angular dimensions - stop at 45 and 90 - marking dimension for parallel lines - determination of drill size with the drilling template. About more than 10 multi-functions: the drilling template is square, protractor, dovetail template, circular hole, parallel line, vertical line, drilling positioning, T-shaped tip, angle ruler 45/ 90. For example: custom colors for labels. Measurement and transfer of angular dimensions. 45 degree and 90 degree angle stop/marking gauge for parallel lines. Drill sizes with the drill guide. Wide range of applications: the false square joinery is suitable for processing three-dimensional workpieces, e.g. beams, squared timber, square and tubular pipes, hollow and solid, aluminum alloy, wood, stainless steel, marble, etc., etc. This is a great gift for a carpenter or plumber. The measurement accuracy: the woodworking measuring ruler itself Clear reading, easy to read and elegant in appearance. You don't have to turn around when measuring. Simply drag to mark the left and right angles of 45 degrees or 90 degrees. 90 angle 90 angle - With this marking tool you can transfer 90 angles to three-dimensional parts. 45 angle. 45 Angle -- With the 45 stop, you can continue to mark the entire workpiece at any time. 3D miter angle 3D miter angle - The 3D miter angle supports you optimally when measuring and marking on three-dimensional workpieces. And the markings are made quickly and precisely in the corners.
