Grade H6810 with CVD coating

The MRMN 500 M H6810 Horn insert is a double-ended carbide insert with a cutting edge width of 5 mm and a full radius R2.5 at the cutting tip, designed for cutting rounded-bottom grooves and profiling radii on conventional and CNC lathes. The 2.5 mm radius spanning the full cutting width creates a semicircular groove profile, making this insert ideal for machining seats for O-rings and sealing rings, as well as lubrication grooves with large cross sections. Cemented carbide grade H6810 with a CVD coating is a versatile grade designed for high-productivity medium machining of steel, offering high cutting edge security even under unfavorable cutting conditions. The insert works with MGMN-type indexable turning tools with a spring clamping system. The 2-edge design allows the insert to be indexed after the first edge wears out, so machining can continue without replacing it.

Key features of the MRMN 500 H6810 Horn insert

  • Radius R2.5 mm at the cutting edge produces a semicircular groove bottom profile, enabling precise machining of O-ring and sealing ring seats in accordance with DIN 3771 and ISO 3601
  • Grade H6810 with high edge security ensures stable operation even during interrupted cutting, with uneven stock allowances and vibrating workpieces, reducing the risk of edge chipping
  • CVD coating resistant to temperatures of 700-1000°C maintains cutting edge stability during intensive grooving at high feed rates
  • Cutting width of 5 mm with M-type geometry enables cutting of profiled grooves 5 mm wide and up to 26 mm deep with a rounded bottom
  • The double-ended design provides 2 independent cutting edges, reducing the machining cost per 1 component by 50 percent
  • The highest rigidity in the MRMN family enables stable machining with long tool overhangs and grooving of deep sealing channels

Frequently asked questions

The MRMN 500 insert has a full radius R2.5 mm spanning the entire cutting width, producing a semicircular groove bottom profile. The MGMN 500 insert has a straight cutting edge with a small corner radius of 0.4 mm and produces a flat-bottom groove. Choose MRMN for O-ring and seal grooves, and MGMN for parting and rectangular grooves.

The MRMN 500 insert with an R2.5 mm radius is ideal for grooves for large O-rings and sealing rings requiring a rounded bottom in accordance with DIN 3771 and ISO 3601. The semicircular groove profile, 5 mm wide, eliminates sharp edges that could damage elastomeric seals during installation. The largest radius in the MRMN family allows thick sealing rings to be used in hydraulic and pneumatic cylinders.

Grade H6810 is a versatile CVD-coated cemented carbide designed for high-productivity machining of structural, alloy, and stainless steels. It offers high cutting edge security under unfavorable conditions, such as interrupted cutting or unstable workpiece clamping. It is also suitable for machining cast iron and cast steel.
