A surform plane is a surface forming tool in the shape of a plane.
What is a surform plane used for?
It’s used to flatten and smooth the surface of a workpiece, by shaving the top layer of material off.
It is also commonly used to reduce the thickness of an object by taking away pieces of material, layer by layer.
Its ability to shave off thin pieces of material means it is useful for creating horizontal, vertical and inclined flat surfaces on a workpiece.
A surform plane is often used for bullnose work, meaning to round off the edges or corners of an object.
It is a tool that can be used on a wide variety of materials, including wood, foam, rubber, soft metals, and plastic.
What are the different types of surform plane?
A surform plane is available in either a flat or a block version. There is also a multi-purpose type available which can be used as both a plane and a file.
Flat plane
A flat plane is ideal for tough materials that may otherwise dull a traditional plane, such as hardwood or soft metals. It is manufactured with a metal body, rather than a plastic one, to allow for heavy-duty use and durability.
Block plane
A block plane is designed with an arched handle for a more comfortable grip during use. These types of plane are ideal for fast stock removal of material or for finishing touches on a workpiece.
Some larger block planes have bodies which are designed for two-handed use.
Planer file
A planer file is a flat plane and a flat file in one. It is a multi-purpose surform, and has a handle which can adjust to allow the tool to be used as either a plane or a file, depending on the task in hand. The handle can either be positioned vertically, to be used as a plane, or horizontally to be used as a file.
