Description
The AC670 is an 8-pack of large diamond honing cones — 3/4-inch narrow end by 1-1/4-inch wide end — for honing and touching up profile knife edges on large-diameter shaper cutters and wide moulder knives. The large cone is suited to the broad profile faces found in raised panel cutters, large-radius ogee profiles, and wide architectural moulding knives where a small cone would require too many passes to cover the full knife face. Used to maintain sharpness between grinds without removing the cutter from the machine. Diamond surface removes wire edge and micro-burrs efficiently. For small diamond honing cones (1/8-inch x 3/8-inch), see AC660. For medium (3/8-inch x 3/4-inch), see AC665. Verify exact cone dimensions and grit specification with Schmidt.
