Product Overview

The Kyocera DCMT11T304GK is a premium-grade 55° Rhombic carbide insert engineered for Heavy Roughing operations in modern CNC turning centers. Featuring the advanced CA125P PVD-coated substrate and the GK chipbreaker geometry, this insert delivers exceptional wear resistance, predictable tool life, and superior surface integrity across a broad spectrum of ferrous materials.

With an inscribed circle of 11.0mm, thickness 3.97mm (5/32"), and a 0.4mm nose radius, the DCMT11T304GK is optimized for roughing and heavy machining. Whether you are running high-volume production or precision prototype work, this insert provides the consistency and reliability that aerospace, automotive, and general engineering shops demand.

ISO Designation Breakdown

The DCMT11T304GK designation follows ISO 1832 standards for indexable inserts. Each code segment communicates critical geometry and application data:

Grade Details — Key Grade Characteristics

CA125P is a high-performance PVD-coated carbide grade developed by Kyocera for universal turning of steel, stainless steel, and cast iron. The multi-layer PVD coating combines titanium aluminum nitride (TiAlN) with an optimized binder phase to achieve:

  • Superior Wear Resistance: Extended tool life in continuous and lightly interrupted cuts, reducing cost per edge.
  • High Thermal Stability: Coating integrity maintained at elevated temperatures, enabling higher cutting speeds.
  • Balanced Toughness: Substrate engineered to resist chipping and fracture under variable machining conditions.
  • Low Coefficient of Friction: Reduced built-up edge (BUE) tendency when machining sticky materials like austenitic stainless steel.
  • Consistent Performance: Tight manufacturing tolerances ensure batch-to-batch predictability for automated production.

Chipbreaker Profile

The GK chipbreaker on the DCMT11T304GK is robust geometry for tough conditions. Key geometric attributes include:

  • Land Width: Optimized for roughing and heavy machining to minimize cutting forces and heat generation.
  • Rake Angle: Positive rake design promotes smooth chip flow and reduces burr formation.
  • Chip Groove Depth: Calculated to curl and break chips into manageable lengths for safe evacuation.
  • Edge Preparation: Heavy Duty honing balances sharpness with edge strength for the intended application range.

Application Map by Operation

OperationRatingRecommendation
External Turning★★★★★Excellent for heavy roughing and stock removal
Internal Turning★★★☆☆Use with rigid boring bars only; minimize overhang
Face Turning★★★★☆Suitable for heavy facing on castings and forgings
Interrupted Cutting★★★★☆Strong edge handles scale, cast skin, and interruptions

Recommended Cutting Conditions

Parameters are starting recommendations for stable setups with adequate coolant. Adjust based on machine rigidity and workpiece condition.

Workpiece MaterialVc (m/min)f (mm/rev)ap (mm)
Carbon Steel150–2200.25–0.501.5–4.0
Alloy Steel130–2000.20–0.451.2–3.5
Stainless Steel100–1600.20–0.401.0–3.0
Cast Iron140–2000.25–0.501.5–4.0

Operating Guidelines

  • Designed for maximum material removal rates in roughing operations
  • Use robust toolholder with shortest possible overhang to absorb cutting forces
  • Ensure machine spindle power ≥ 5kW for size 11 inserts at full depth
  • Apply heavy-duty coolant concentration to manage heat in deep cuts
  • Monitor insert for crater wear; GK geometry provides strong cutting edge protection
