Grade Details – Key Grade Characteristics
The KW10 grade is an ultra-fine grain carbide specifically developed for machining non-ferrous metals, cast iron, and non-metallic materials. Key characteristics include:
- Exceptional hardness and wear resistance for uncoated grades
- Superior edge sharpness retention in non-ferrous applications
- Low coefficient of friction against aluminum and copper alloys
- High thermal conductivity for stable high-speed machining
- Excellent surface finish generation on cast iron and titanium

| Copying / Profiling | ★★★★★ Excellent | Reduce ap by 30% at profile transitions |
| Back Boring | ★★★★☆ Very Good | Use minimum overhang, rigid setup |
| Sub-Spindle Work | ★★★★☆ Very Good | Match hand to spindle rotation |
| Face Turning | ★★★☆☆ Good | Limit to light depths for finishing |
Recommended Cutting Conditions
Parameters below are starting recommendations for stable machining with flood coolant or minimum quantity lubrication (MQL). Adjust based on machine rigidity and workpiece fixturing.
| Workpiece Material | Cutting Speed (vc) | Feed Rate (f) | Depth of Cut (ap) |
|---|---|---|---|
| Aluminum | 400–1000 m/min | 0.03–0.10 mm/rev | 0.05–0.5 mm |
| Copper | 250–600 m/min | 0.03–0.08 mm/rev | 0.05–0.4 mm |
| Magnesium | 300–800 m/min | 0.05–0.15 mm/rev | 0.1–0.6 mm |
| Plastic | 200–500 m/min | 0.05–0.15 mm/rev | 0.1–1.0 mm |
Operating Guidelines
- Always verify insert seat cleanliness before indexing to prevent micro-chipping.
- Use balanced toolholders (G2.5 or better at 25,000 rpm) for sub-spindle applications.
- Apply consistent coolant flow to minimize thermal cracking on uncoated carbide edges.
- For titanium alloys, reduce cutting speed by 20% and increase feed slightly to avoid work-hardening.
- Store inserts in original packaging away from moisture and corrosive atmospheres.
- Inspect nose radius wear every 15–20 minutes of cutting time when machining abrasive cast iron.
Toolholder Compatibility
This insert is compatible with standard 07-series external turning holders with 93° or 107.5° approach angle toolholders. Recommended clamp systems include lever-lock and screw-clamp designs for secure seating during high-speed operations.
Compatible Holder Families: SDJCR/L 07, SDNCN/L 07, SVJCR/L 07, SVVCN/L 07, STFCR/L 07, STGCR/L 07
Verify holder designation matches insert hand (Right-Hand) and inscribed circle (1/4") before purchase.
