Grade H6018 with CVD coating

The MRMN 200 M H6018 Horn insert is a double-ended carbide insert with a cutting width of 2 mm and a full radius R1 at the cutting tip, designed for cutting round-bottom grooves and profiling radii on conventional and CNC lathes. The 1.0 mm radius spanning the entire cutting width produces a semicircular groove profile, making this insert ideal for machining O-ring seats, sealing ring seats, and lubrication grooves. CVD-coated cemented carbide grade H6018 is a versatile grade designed for high-productivity medium machining of steel, offering high cutting edge security even under unfavorable cutting conditions. The insert fits 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 replacement.

Key features of the MRMN 200 H6018 Horn insert

  • Radius R1.0 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 H6018 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 2 mm with M-type geometry enables cutting of profiled grooves 2 mm wide and up to 16 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
  • Compatibility with MGMN-type holders with shank sizes of 16x16 mm, 20x20 mm, 25x25 mm, and 32x32 mm, as well as internal grooving blades

Frequently asked questions

The MRMN 200 insert has a full radius R1.0 mm spanning the entire cutting width, producing a semicircular groove bottom profile. The MGMN 200 insert has a straight cutting edge with a small corner radius of 0.2 mm and produces a flat-bottom groove. Choose MRMN for O-ring and seal grooves, and MGMN for parting and rectangular grooves.

The MRMN 200 insert with an R1.0 mm radius is ideal for grooves for O-rings and sealing rings requiring a rounded bottom in accordance with DIN 3771 and ISO 3601. The semicircular groove profile eliminates sharp edges that could damage elastomeric seals during installation.

Grade H6018 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.
