Product Overview

The Kyocera DNMG150408GC CA315 TMD02040 is a precision-manufactured indexable carbide turning insert designed for modern CNC machining centers. Built on a fine-grained tungsten carbide substrate and finished with a multi-layer PVD coating, this insert delivers consistent performance across steel, stainless steel, and cast iron applications.

With its 55° Rhombic (Diamond) geometry and general purpose profile, the DNMG150408GC is optimized for medium turning, general machining operations where versatility is the primary objective. The 0.8 mm nose radius ensures stable cutting action while maintaining dimensional accuracy over extended tool life.

ISO Designation Breakdown

The DNMG150408GC designation follows the ISO 1832 standard for indexable inserts. Each letter and number encodes critical geometric and functional data:

Grade Details – Key Grade Characteristics

The CA315 grade is a PVD-coated carbide grade engineered for medium to high-speed machining of ferrous materials. It combines a hard, wear-resistant coating with a tough, fine-grained substrate to resist both abrasive and adhesive wear mechanisms.

  • Excellent wear resistance at medium to high cutting speeds
  • Superior adhesion strength between coating and substrate
  • Optimized for wet and dry machining environments
  • Stable performance in continuous and light interrupted cuts
  • Good balance of toughness and hardness for versatile applications

Recommended Cutting Conditions

The following parameters represent starting recommendations. Optimize based on machine rigidity, workpiece condition, and coolant delivery:

ParameterCarbon SteelStainless SteelCast Iron
Cutting Speed (Vc)180–260 m/min110–170 m/min140–200 m/min
Feed Rate (fn)0.15–0.35 mm/rev
Depth of Cut (ap)1.0–4.0 mm
PriorityVersatility

Note: Values are starting recommendations. Reduce speed by 15–20% for hardened materials or interrupted cuts. Increase feed up to 0.6 mm/rev for heavy roughing with KG/KH geometries.

Operating Guidelines

Adhering to these guidelines ensures maximum tool life, surface quality, and process safety:

  • Versatile chipbreaker allows feed range 0.15–0.35 mm/rev without chip packing
  • Coolant recommended for stainless steel to prevent built-up edge
  • Dry machining acceptable for cast iron and short-chipping steels
  • Tool overhang should not exceed 4× toolholder height for stability
  • Regular inspection of flank wear recommended at 15-minute intervals

Toolholder Compatibility

The DNMG150408GC conforms to the DNMG standard and is compatible with all ISO-standard 55° rhombic toolholders designed for cylindrical-hole inserts with chipbreakers. Recommended toolholder styles include:

  • DDJNR / DDJNL – 55° External Turning Toolholder
  • MDJNR / MDJNL – Multi-purpose External Turning
  • PDJNR / PDJNL – Precision External Turning
  • SVJBR / SVJBL – 93° Toolholder (with shim)
  • DVJNR / DVJNL – 93° Vertical Mounting

Mounting Requirements: Use a torque wrench set to 2.5–3.0 N·m for M2.5 clamp screws. Ensure insert seat is clean and free of chips before mounting. Use precision shim (if required) to maintain cutting edge height within ±0.05 mm of spindle centerline.
