Diager© 4013--0400A drill bit

Single-tooth right-hand helical end mill – Diager – 4013-0400A

The Diager 4013-0400A cutter is a solid carbide cutting tool designed for milling, cutting and grooving soft materials on CNC routers, router tables or digital cutting table milling modules.

It features a single right-hand helical tooth (upcut) geometry, with a smooth, polished flute that minimises clogging and ensures efficient upward chip evacuation. This configuration guarantees a clean cut, a smooth surface finish and extended cutting edge life on non-metallic materials.

Supplied as a single tool (without a shank), it fits any tool holder with a standard Ø6 mm shank. For Zünd cutting tables requiring a shanked cutter, please refer to version 4013-0400C-B.

Function

• Cutting and grooving of wood (solid wood, plywood, MDF, composite panels)
• Machining of engineering plastics: PVC, expanded PVC, PMMA, thermoplastics and thermosets
• Cutting of foams, compact laminates and aluminium-core composite panels
• Upward chip evacuation via the right-hand spiral (upcut) for a clean plunge cut
• Production of contoured edges, narrow grooves and precision cuts

Possible signs of wear

• Rough cut with burrs, splinters or uncut fibres at the cutting edge
• Chip build-up in the kerf and abnormal tool heating
• Irregular cutting noise, increased vibration or tool deflection
• Burning of the material (wood, plastics) on the groove walls
• Chip breakage or tool fracture during machining

Regular replacement of the 4013-0400A cutter ensures cutting quality, dimensional accuracy of the parts produced and operator safety on the machine.
