FLAT TECHNICAL INFORMATION

Edge Profile & Angle

Bevel Surface and Characteristic

Shaved bevel

– Very high degree of accuracy and edge straightness as well as excellent bending properties.
– Longer life span than ground type.
– For the materials like Manila, corrugated boxes, all kinds of package.
– Less edge crack than ground type.

Ground bevel

– Good cutting results due to micro-teeth on the bevel.
– For the materials like plastics, rubber and laminate etc.
– The high sharpness and low friction reduce formation of dust and angel hairs.
– In comparison to the shaved execution, it has a slightly reduced bendability.
