The standard serrated cutter can be used for most jobs, but the machine can be fitted with coarse serrated or fine serrated cutters as required. Coarser teeth are used for larger bevel widths in heavy material and fine teeth are intended for use in lighter work with smaller bevel widths up to 15 mm. Cutters are made from hardened alloy tool steel.
High performance bevel
1. Maximum bevel is 25 mm and is possible to achieve in plate with a tensile strength of 390 N/mm².
2. Maximum tensile strength to be beveled is 690 N/mm² and gives a bevel of 13 mm.
Fine-toothed cutter gives the smoothest cut. Difficulties, however, could arise with feeding, when bevelling harder or tougher materials, especially if the bevel is deep. In such cases a coarse-toothed cutter has to be used.
Standard cutters are recommended for materials with a tensile strength below 550 N/mm².
High tensile “chipper” cutters are recommended for materials with a tensile strength between 550 N/mm² and 690 N/mm²).
