Kyocera GVR200SS KW10 Grade Uncoated Carbide, Indexable Grooving Insert
Product Overview
The Kyocera GVR200SS KW10 Grade Uncoated Carbide Grooving Insert (Manufacturer Part Number: TWE02340) is a precision-engineered indexable insert designed for external grooving. Manufactured in Japan from premium sub-micron carbide with a 2.00 mm groove specification, this right-hand insert delivers exceptional dimensional accuracy and surface finish quality. The KW10 grade provides a sharp, uncoated cutting edge ideal for mirror-finish machining of aluminum, copper, cast iron, and titanium alloys.

Chipbreaker Profile
The SS-type chipbreaker (Super Sharp) features an ultra-fine, micro-polished cutting edge with minimal land width. This profile is specifically engineered for super-finishing operations and small-part machining where mirror surface finishes are required. The extremely low cutting forces make it perfect for thin-walled components and precision medical devices.
Recommended Applications & Workpiece Materials

| Aluminum & Alloys | 6061-T6, 7075-T6, 2024, A356 | Excellent - Mirror Finish |
| Copper & Alloys | C11000, C36000, Beryllium Copper | Excellent - High Precision |
| Cast Iron | GG25, GGG40, FC250, FCD400 | Good - Stable Cutting |
| Titanium Alloys | Ti-6Al-4V, Ti-6Al-2Sn-4Zr-2Mo | Good - Low Speed Recommended |
| Plastics & Composites | POM, PTFE, GFRP, CFRP | Excellent - Clean Cut |
| Non-Metallic | Graphite, Ceramics, Wood | Good - Dust Control Required |
Application Map by Operation
| Operation | Suitability | Notes |
|---|---|---|
| External Grooving | ★★★★★ | Primary application |
| Internal Grooving | ★★★★☆ | With minimum bore diameter check |
| Face Grooving | ★★★☆☆ | Limited by holder access |
| Cut-Off | ★☆☆☆☆ | Not recommended |
| Profiling | ★★★☆☆ | Possible with shallow depths |
Recommended Cutting Conditions
Starting parameters for KW10 grade. Adjust based on machine rigidity, workpiece condition, and required surface finish:
| Material | Vc (m/min) | fn (mm/rev) | DOC (mm) |
|---|---|---|---|
| Aluminum | 200 - 400 | 0.05 - 0.15 | Up to groove width |
| Copper | 150 - 300 | 0.05 - 0.12 | Up to groove width |
| Cast Iron | 80 - 150 | 0.08 - 0.20 | Up to groove width |
| Titanium | 30 - 60 | 0.05 - 0.10 | Up to 0.5 × width |
Operating Guidelines
- Coolant: Flood coolant recommended for aluminum and copper to prevent built-up edge. Dry cutting acceptable for cast iron. Use high-pressure coolant for titanium alloys.
- Toolholder: Ensure holder pocket is clean and undamaged. Use correct torque when clamping (typically 2.5 - 3.5 N·m for M2.5 screws).
- Runout: Maintain radial runout below 0.01 mm at the cutting edge for optimal surface finish and tool life.
- Entry: Use ramp or helical entry for grooving and drilling operations. Avoid plunging directly into solid material at full depth.
- Edge Inspection: Inspect inserts after 30 minutes of cutting for wear patterns. Replace when flank wear exceeds 0.15 mm or when chipping is observed.
- Storage: Store inserts in original packaging away from moisture and direct sunlight. Handle with gloves to prevent corrosion from skin oils.
