Blades of various different shapes and sizes are available for different types of surform tool.
Flat
A flat blade can also be referred to as a standard surform blade. It has a long, straight shape, meaning it is often used for working on flat surfaces. Some versions have side-cut teeth along one edge which are useful when shaving into corners and working along edges. It can be used on a number or materials, including wood, plaster, PVC, soft metals and fibreglass.
It is commonly used as a general purpose blade, and is ideal for initial and rapid stock removal from a workpiece.
This type of blade is usually seen on a surform flat plane or flat file.
A flat surform blade is 250mm (10″ approx.) in length.
Round
A round type is a circular surform blade – it looks like a pipe with holes in it. It can be used on many materials, such as wood, soft metals, plastics and laminates.
It is the ideal type for shaping tight curves into a workpiece, along with sculpting or enlarging holes within an object.
This type of blade is designed to be used as part of a surform round file.
A round surform blade is generally 250mm (10″ approx.) in length.
Half round
A half round blade is a cross between a flat and a round type, having a rounded curve to its surface. It is versatile and can be used on a variety of materials, including working on fibreglass and removing filler from surfaces.
It is ideal for the fast removal of material from a workpiece, along with shaping curved surfaces. A half round blade is particularly useful for working on concave surfaces, as the curvature of the blade can accommodate the shape of the material.
A half round surform blade is usually 250mm (10″ approx.) in length.
Fine cut
A fine cut surform blade looks similar in appearance to a flat blade, but has slightly smaller perforated holes than the other types. It is designed to create a smoother finish on a workpiece, and is used particularly on hardwoods, end grain (the grain at the ends of a length of wood) and some soft metals.
This type of blade is usually used within a surform plane or a surform file.
A fine cut blade is available in two sizes: 250mm (10″ approx.) and 140mm (5.5″ approx.) in length.
Shaver
A shaver blade is much smaller than the other types of blade, meaning it is commonly used for filing down small or awkward places that larger blades may not be able to fit. It is designed with side-cut teeth along one edge, meaning it is ideal for cutting into tight corners. It is also an ideal blade for stripping paint and smoothing down filler.
This type of blade is found on a surform shaver tool.
A shaver blade is commonly 60mm (2.5″ approx.) in length.
