Product Overview
The CNMG090404GS CA115P TML00089 is a precision-engineered indexable carbide turning insert manufactured by Kyocera in Japan. Designed for general steel turning, this general-purpose chipbreaker insert combines a fine-grained carbide substrate with an advanced TiAlN PVD coating to deliver exceptional performance in CNC turning centers and milling machines.
With an 9.525 mm (3/8") inscribed circle, 4.760 mm (3/16") thickness, and 0.4 mm (1/64") nose radius, the CNMG090404GS offers sharp cutting capability for fine finishing operations. The general-purpose chipbreaker geometry ensures reliable chip control across a wide range of feed rates and depths of cut, making it an ideal choice for reliable general production environments.
ISO Designation Breakdown
The CNMG090404GS follows the ISO 1832 standard insert designation system, providing complete geometric and tolerance information at a glance:
- C – Insert shape: 80° rhombic (diamond) with acute corners, ideal for versatile turning and facing operations
- N – Normal clearance angle: 0°, providing maximum edge strength for heavy-duty applications
- M – Tolerance class: ±0.08 mm on inscribed circle (IC), ±0.05 mm on thickness (S), ±0.13 mm on corner height
- G – Hole and chipbreaker type: Cylindrical hole with counterbore, chipbreaker on both rake faces (double-sided usability)
- 09 – Inscribed circle diameter: 9.525 mm (3/8")
- 04 – Nominal thickness: 4.760 mm (3/16")
- 04 – Corner radius: 0.4 mm (1/64") – sharp edge for fine finishing
- GS – Chipbreaker code: General-Purpose Chipbreaker for General Steel Turning
Engineering Dimensions & Geometry
Precision-machined dimensions ensure perfect seat contact and repeatability in CNC toolholders:
| Parameter | Value | Tolerance |
|---|---|---|
| Inscribed Circle (IC) | 9.525 mm (3/8") | ±0.08 mm |
| Thickness (S) | 4.760 mm (3/16") | ±0.05 mm |
| Corner Radius (RE) | 0.4 mm (1/64") | ±0.10 mm |
| Hole Diameter | 4.4 mm | H6 |
| Counterbore Diameter | 8.5 mm | +0.1 mm |
| Inscribed Circle Height | 6.35 mm | ±0.13 mm |
The 0° clearance angle (N-type) provides a straight flank that seats firmly against the toolholder pocket, maximizing stability during aggressive cuts. The general-purpose chipbreaker geometry is precision-ground to ±0.01 mm form accuracy.
Grade Details - Key Grade Characteristics
The CA115P grade is a premium PVD-coated carbide specifically engineered for steel turning applications. Key characteristics include:
- Substrate: Fine-grained tungsten carbide with high cobalt content for optimal toughness
- Coating System: Multi-layer PVD coating with TiAlN-based architecture
- Coating Color: Bronze-copper – visual wear indicator for easy tool-life monitoring
- Microhardness: HRA 91.5 – balancing hardness and toughness
- TRS: ≥ 2,800 MPa – high mechanical strength resists chipping
- ISO Application: ISO P15–P30 (Steel machining)
- Max Operating Temp: 800°C (1,472°F)
- Wear Performance: Excellent crater and flank wear resistance in continuous to medium-interrupted cutting
The TiAlN-based PVD coating delivers exceptional oxidation resistance and thermal stability, maintaining coating integrity at elevated cutting temperatures typical in steel machining. The fine-grained substrate structure minimizes crack propagation, extending insert life in both continuous and interrupted cuts.
Grade Comparison Matrix
| Grade | Coating | ISO Range | Wear Resistance | Toughness | Best For |
|---|---|---|---|---|---|
| CA115P | PVD TiAlN | P15–P30 | ★★★★☆ | ★★★★☆ | Steel turning, general purpose |
| CA125P | PVD TiAlN | P20–P35 | ★★★☆☆ | ★★★★★ | Interrupted cuts, heavy roughing |
| CA105P | PVD TiAlN | P10–P20 | ★★★★★ | ★★★☆☆ | High-speed finishing, precision |
| CA530 | CVD TiCN-Al₂O₃ | P15–P35 | ★★★★☆ | ★★★★☆ | High-speed steel turning |
Chipbreaker Profile
The GS chipbreaker on the CNMG090404GS is specifically designed for general steel turning:
- Balanced cutting force distribution
- Wide application window
- Consistent chip formation
- Good surface finish at moderate speeds
Versatile general-purpose chipbreaker suitable for a wide range of steel machining applications. Balanced geometry provides consistent performance across varying cutting conditions. The chipbreaker land width is optimized for the 0.4 mm (1/64") nose radius, ensuring proper chip curl and breakage without compromising edge integrity. Chip flow angle is designed to direct chips away from the workpiece surface, preventing scratching and ensuring safe evacuation.
Recommended Applications & Workpiece Materials
The CNMG090404GS with CA115P grade is optimized for the following workpiece materials and operations:
- Primary Materials: Carbon steel, alloy steel, stainless steel, free-cutting steel (ISO P10-P30)
- Hardness Range: 80–350 HB (ideal up to 280 HB for optimal tool life)
- Surface Condition: Suitable for standard mill-scale and machined surfaces
- Machine Types: CNC turning centers, multi-tasking machines, Swiss-type lathes, conventional engine lathes with proper holders
For best results, ensure rigid workpiece clamping and minimal tool overhang. Use high-pressure coolant (70+ bar) for deep-hole boring applications to improve chip evacuation and surface finish.
Application Map by Operation
| Operation | Suitability | Notes |
|---|---|---|
| External Turning | ★★★★☆ Very Good | Primary application; use recommended speeds/feeds |
| Internal Boring | ★★★★☆ Very Good | Smaller IC preferred for bore diameters <25 mm |
| Facing | ★★★★☆ Very Good | Reduce feed by 20% when facing to center to avoid chip crowding |
| Profiling / Copy Turning | ★★★★☆ Very Good | 0.4 mm (1/64") radius provides fine detail capability |
| Interrupted Cutting | ★★★☆☆ Good | Reduce speed by 30% for cast skin or scale |
| Heavy Roughing | ★★★☆☆ Good | Limited by chipbreaker depth capacity |
Recommended Cutting Conditions
Recommended starting parameters for general steel turning with CA115P:
| Parameter | Starting Value | Range |
|---|---|---|
| Cutting Speed (Vc) | 195 m/min | 140–250 m/min |
| Feed Rate (fn) | 0.225 mm/rev | 0.10–0.35 mm/rev |
| Depth of Cut (ap) | 2.2 mm | 0.5–4.0 mm |
Coolant Recommendation: Water-soluble coolant (5–10%) recommended for optimal tool life and surface finish. For dry machining, reduce cutting speed by 15–20%.
Operating Guidelines
- Toolholder Selection: Use M-class holders (MCLNR/L, MCKNR/L) with matching shim seat for 9.525 mm (3/8") inserts. Ensure holder pocket is clean and undamaged.
- Insert Seating: Verify full contact between insert bottom and shim seat. A 0.02 mm feeler gauge should not pass under the insert when properly seated.
- Clamping Torque: Tighten lever to 2.5–3.5 N·m. Over-tightening can distort the insert; under-tightening causes vibration and poor finish.
- Run-out Check: Maintain radial run-out <0.01 mm at the cutting edge. Excessive run-out causes uneven wear and poor surface finish.
- Entry Strategy: Prefer arc-in entry for best surface finish; direct entry acceptable for roughing
- Edge Life Monitoring: Monitor flank wear (VB). Replace insert when VB reaches 0.3 mm for roughing or 0.15 mm for finishing to maintain dimensional accuracy.
- Chip Control: If chips are too long or bird-nesting, increase feed by 10% or verify coolant delivery to the cutting zone.
Toolholder Compatibility
- External Turning: MCLNR/L, MCKNR/L, MCMNN (95° toolholders with 80° insert seat)
- Internal Boring: S20R-MCLNR11, S25S-MCLNR12 (boring bars with CNMG pocket)
- Facing: MCFNR/L (45° face milling style holders)
- Profiling: MDJNR/L (93° approach angle for copy turning)
- Clamp System: Lever lock or top-clamp systems compatible with M-class inserts
- Shim Requirement: Use matching shim seat (e.g., MC1204, MC1606) for optimal support
