Surform planer
The Surformhobel , sometimes surform file , ( English : "surface-forming" = shaping surface) is a tool for the machining of relatively soft materials such as wood , gypsum , plastic and soapstone . The surface of the material is machined by removing chips from the material with a plane.
construction
The Surform plane has an exchangeable underside (sole) on which a large number of small cutting edges are punched out like a grid. The sole is usually about 15 cm long and about 5 cm wide. The plane body is mostly made of cast iron . The Surform plane is an intermediate form between plane and rasp .
The bottom of the plane rests on the workpiece. The cutting performance and surface quality are primarily dependent on the sharpness of the cutting edges. The symmetrical structure of the Surform plane means that it can be used equally well by right- or left-handers.
history
Developed and patented at the end of the 1940s, Surform tools have been on the market since the early 1950s.
