Grade Details - Key Grade Characteristics
KW10 is a premium uncoated fine-grain tungsten carbide grade in the ISO K10 classification. It is engineered specifically for machining non-ferrous metals, cast iron, and non-metallic materials where built-up edge resistance and surface finish are paramount.
- Substrate: Ultra-fine WC-Co grain structure (≈0.5–0.8 μm)
- Coercivity: High, indicating uniform grain distribution and excellent edge stability
- Hardness: ~92.0 HRA, providing superior wear resistance at elevated speeds
- Transverse Rupture Strength: Moderate, optimized for stable finishing rather than heavy interrupted cutting
- Binder Content: Balanced cobalt level for toughness without sacrificing hardness
- Surface Finish: Mirror-polished rake and flank faces to minimize friction and material adhesion
Grade Comparison Matrix
| Grade | ISO Class | Coating | Best For | Speed Range |
|---|---|---|---|---|
| KW10 | K10 | Uncoated | Non-ferrous, Cast Iron, Titanium | Medium–High |
| PR630 | P15–P30 | PVD | Steel, Stainless Steel | Medium |
| CA530 | P30–P40 | CVD | General Steel Machining | Low–Medium |
| TN620 | P10–P20 | CVD | High-Speed Steel Turning | High |
Chipbreaker Profile
The S-type chipbreaker is a specialized geometry for negative inserts performing facing and turning under variable depths of cut. It combines a strong cutting edge with a moderate chip curl radius to handle both continuous and lightly interrupted cuts. The robust land design provides security when entering cast iron skin layers.
Recommended Applications & Workpiece Materials
The CNGG090404L-S KW10 is recommended for the following workpiece materials and operations:
- Aluminum & Aluminum Alloys: Excellent for wrought and cast grades; mirror finish achievable at high speeds
- Copper & Copper Alloys: Prevents material adhesion and built-up edge; ideal for electrical component machining
- Cast Iron (Gray & Ductile): Stable cutting at medium speeds; good abrasion resistance against graphite inclusions
- Titanium & Titanium Alloys: Low cutting forces reduce work hardening; polished rake minimizes chemical affinity
- Plastics & Composites: Sharp edge prevents delamination and fiber pull-out in CFRP/GFRP
- Brass & Bronze: Long tool life with minimal edge chipping; excellent for decorative turned parts
Application Map by Operation
| Operation | Suitability | Recommended DOC | Feed Range |
|---|---|---|---|
| External Turning | ★★★★☆ | 0.1–1.5 mm | 0.05–0.25 mm/rev |
| Internal Facing | ★★★★★ | 0.1–1.0 mm | 0.05–0.20 mm/rev |
| Boring | ★★★★★ | 0.05–0.8 mm | 0.03–0.15 mm/rev |
| Back Boring | ★★★★☆ | 0.05–0.5 mm | 0.03–0.12 mm/rev |
| Copying / Contouring | ★★★★★ | 0.05–0.5 mm | 0.03–0.15 mm/rev |
| Sub-Spindle (Swiss) | ★★☆☆☆ | 0.03–0.3 mm | 0.02–0.10 mm/rev |
Recommended Cutting Conditions
Parameters below are starting recommendations for stable machining with flood coolant or mist application. Adjust based on machine rigidity and workpiece fixturing.
| Material | Cutting Speed (Vc) | Feed (fn) | DOC (ap) |
|---|---|---|---|
| Aluminum Wrought | 300–600 m/min | 0.05–0.25 mm/rev | 0.1–2.0 mm |
| Aluminum Cast | 250–450 m/min | 0.05–0.20 mm/rev | 0.1–1.5 mm |
| Copper | 200–400 m/min | 0.05–0.20 mm/rev | 0.1–1.0 mm |
| Gray Cast Iron | 100–200 m/min | 0.08–0.25 mm/rev | 0.2–2.0 mm |
| Titanium Alloy | 40–80 m/min | 0.05–0.15 mm/rev | 0.1–0.8 mm |
| Brass / Bronze | 150–300 m/min | 0.08–0.25 mm/rev | 0.1–1.5 mm |
Operating Guidelines
- Coolant: Flood soluble oil or synthetic coolant is strongly recommended for aluminum and titanium to prevent built-up edge and extend tool life.
- Tool Overhang: Minimize overhang for boring operations; use anti-vibration toolholders when L/D exceeds 4:1.
- Edge Preparation: Do not hone or alter the factory-polished edge; micro-honing will increase cutting forces and reduce finish quality.
- Indexing: Ensure the insert seat is clean and free of chips before indexing; torque clamping screws to manufacturer specification.
- Speed Ramp: When starting a new job, begin at the lower end of the recommended Vc range and increase gradually while monitoring surface finish and chip form.
- Storage: Store inserts in original packaging away from moisture and corrosive atmospheres to prevent edge degradation.
Toolholder Compatibility
Compatible toolholder families for the CNGG left-hand insert:
- STFCR / STFCL – 60° triangle external turning holders (right-hand / left-hand)
- SCLCR / SCLCL – 95° approach angle cylindrical turning holders
- SSKCR / SSKCL – 45° approach angle facing and turning holders
- E10K-STFCR / E12K-STFCL – Mini-boring bars for small-diameter internal work
- A16M-SCLCR – Anti-vibration boring bar for deep-hole applications
- PDJNR / PDJNL – 93° approach angle for heavy-duty turning
Always verify toolholder seat geometry (ISOI) and clamping system (lever lock, screw clamp, or pin lock) before mounting.
Packaging & Ordering Information
- Packaging: Each insert is individually blister-packed in a protective plastic pocket to prevent edge damage during transit. Multiple inserts are arranged in a Kyocera-branded retail box with moisture-resistant lining.
- Minimum Order: 10 pieces per line item (standard pack quantity).
