A. Coarse serration: This cutter is recommended when performing maximum dimensions of bevels on large and heavy work pieces.

B. Medium serration: Suitable for large bevels on small work pieces.

C. Fine serration: Advantageous for all materials when the width of the bevel is below 15 mm (0.590″ or 19/32″) and when the weight of the work piece is below 50 kg (110 lbs).
