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

| Rake Angle Geometry | Positive rake with narrow land width |
| Groove Depth | 0.05–0.15 mm |
| Recommended Feed (f) | 0.05–0.15 mm/rev |
| Recommended Depth of Cut (ap) | 0.1–1.0 mm |
Recommended Applications & Workpiece Materials
The DCGT070201R-F with KW10 grade and F-Type Finishing Chipbreaker is optimized for the following material groups and machining scenarios:
- Primary Materials: Aluminum alloys (1xxx–7xxx series), Copper, Brass, Bronze, Cast iron (gray/ductile), Titanium alloys (Ti-6Al-4V), Plastics, Composites
- Supported Operations: External turning, Copying, Back boring, Sub-spindle finishing, Face turning, Grooving (light)
- Target Industries: Aerospace, Automotive, Medical devices, Electronics, Precision engineering
Application Map by Operation
| Operation | Suitability | Recommended Parameters |
|---|---|---|
| External Turning | ★★★★★ Excellent | ap = 0.1–1.0 mm, f = 0.05–0.15 mm/rev |
| 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 | 300–800 m/min | 0.05–0.15 mm/rev | 0.1–1.0 mm |
| Copper | 200–500 m/min | 0.05–0.12 mm/rev | 0.1–0.8 mm |
| Cast Iron | 150–300 m/min | 0.08–0.20 mm/rev | 0.2–1.5 mm |
| Titanium | 40–80 m/min | 0.05–0.12 mm/rev | 0.1–0.8 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.
