DNMG Inserts

DNMG Inserts – High-Performance Carbide Inserts for Semi-Finishing & Finishing

What Are DNMG Inserts?

DNMG inserts are 55° diamond-shaped, double-sided carbide inserts with a negative rake angle, designed for medium to finishing applications in CNC turning operations. Known for their strong cutting edges, DNMG inserts strike a perfect balance between strength, chip control, and surface finish—making them ideal for both light roughing and semi-finishing on a variety of workpiece materials.

DNMG Code Explained:

  • D – 55° diamond shape (used for profiling and taper turning)

  • N – 0° relief angle (neutral rake, strong cutting edge)

  • M – Medium tolerance class

  • G – Type of chipbreaker/clamping system

These inserts have 4 cutting tips per insert (2 per side), offering excellent value while maintaining performance in demanding turning environments.

 

Key Features of DNMG Inserts

  • Geometry: 55° diamond shape – ideal for profiling and taper applications

  • Relief: Neutral (0°) for high rigidity and edge strength

  • Usable Cutting Edges: 4 total (2 per side)

  • Versatile: Suitable for steel, stainless steel, cast iron, and more

  • Finishing to Light Roughing: Excellent for semi-finishing cuts in continuous or slightly interrupted cuts

  • Toolholder Fit: Designed for clamp-style toolholders in standard turning setups

 

Applications

  • Medium and finishing operations in steel, alloy steel, and cast iron

  • External and internal turning where precision and chip control are critical

  • Profiling and taper turning in high-precision CNC lathe jobs

  • Used in industries such as automotive, aerospace, die & mold, and general engineering

 

Material Grades & Coating Options

DNMG inserts are available in high-performance grades with the following options:

  • Base Materials: Carbide, Cermet, and Ceramic

  • Coatings:

    • CVD Coatings: TiCN, Al₂O₃, TiN – for longer tool life in continuous cuts

    • PVD Coatings: TiAlN, AlCrN – for tougher applications, especially stainless and exotic materials

    • Uncoated: For ultra-precision applications requiring sharp edges

Frequently Asked Questions

DNMG inserts are used for medium to finishing CNC turning operations, especially for profiling, taper turning, and semi-finishing in steel and cast iron.

DNMG = D: 55° diamond shape, N: 0° relief, M: medium tolerance, G: chipbreaker/clamping type.

A DNMG insert has 4 usable edges—2 on each side, making it cost-effective for high-volume use.

Yes, DNMG inserts are ideal for semi-finishing and finishing due to their edge sharpness and chip control features.

Yes, with appropriate grades and coatings (e.g., PVD-coated DNMG), they perform well on stainless and other difficult-to-machine materials.

DNMG inserts are more robust with a thicker edge, suitable for semi-finishing. VNMG inserts have a sharper 55° shape ideal for fine finishing and profiling.

Common chipbreakers include MA (finishing), MP (medium), MM (light roughing), and GM (universal).

Yes, depending on the toolholder used, DNMG inserts are suitable for both ID and OD turning.

DNMG inserts are available in multiple carbide and cermet grades, with both PVD and CVD coatings depending on the cutting application.

You can buy DNMG inserts online from CNC Tools Depot, with expert support, fast delivery, and industry-grade quality.
