Product Description

Johnson''s 420em-s combination square features a self-aligning drawbolt, etched stainless steel blade with 1/8'', 1/16'', 1/32'' and mm graduations, heavy duty 45° and 90° precision machined square head and a hardened removable scriber. A combination square is a tool used for multiple purposes in woodworking, stone masonry and metal working. A combination square can reliably measure 90° and 45° angles. The 45° angle is used commonly in creating miter joints. It can be used to determine Flatness on a board known as the face side. It can be a rudimentary level for approximating level surfaces. A combination square can be used as a depth gauge or to transfer dimensions and the scribe can be used for marking the work surface.
