Different types of surform tool are available in various sizes. The majority of surform tools are the same size in terms of width at around 40mm (1.5″ approx.), however, the length can vary.
Surform file
A surform file is available in different sizes, depending on the type.
A flat surform file is available in the two following lengths:
335mm (13″ approx.), using a 140mm (5.5″ approx.) blade.
440mm (17″ approx.), using a 250mm (10″ approx.) blade.
A round surform file differs slightly, as it is the only type which has a blade narrower than the standard width.
The dimensions of a round surform file are as follows:
365mm (14″ approx.) in length, using a 250mm (10″ approx.) blade.
15mm (0.5″ approx.) in width.
Surform plane
A surform plane is also available in various lengths.
A flat surform plane is available in one length:
315mm (12″ approx.), using a 250mm (10″ approx.) blade.
A block surform plane is available in two lengths, depending on the model:
150mm (6″ approx.), using a 140mm (5.5″ approx.) blade.
270mm (10.5″ approx.), using a 250mm (10″ approx.) blade.
A planer file surform is similar in size to a flat plane and is designed in the following length:
310mm (12″ approx.), using a 250mm (10″ approx.) blade.
Surform shaver
There is only one type of surform shaver and, therefore, it is available in one size only.
A surform shaver is the following length:
185mm (7″ approx.), using a 60mm (2.5″ approx.) blade.
