Kyocera GVFR450C KW10 Grade Uncoated Carbide, Indexable Grooving Insert
Product Overview
The Kyocera GVFR450C KW10 Grade Uncoated Carbide Indexable Face Grooving Insert is a precision-engineered cutting tool manufactured by Kyocera in Japan. ensures mirror-finish quality and precise groove profiles, making it ideal for CNC turning centers performing face grooving and recessing operations on flat workpiece surfaces. The GVFR450C features a mm cutter width with right-hand orientation, engineered to produce accurate groove profiles perpendicular to the workpiece axis. ensures repeatable results across batch operations.

Grade Details - Key Grade Characteristics
KW10 is a premium uncoated fine-grain tungsten carbide grade engineered by Kyocera for high-precision face grooving and recessing applications. The micro-grain structure (sub-micron particle size) provides an optimal balance of hardness and toughness, delivering a sharp, stable cutting edge that maintains groove accuracy over extended machining cycles on flat surfaces.
- Substrate: Ultra-fine WC-Co carbide (ISO K10 equivalent classification)
- Hardness: ~91.5 HRA, providing excellent wear resistance at moderate speeds
- Coating: Uncoated (bare substrate) to preserve edge sharpness for fine face grooving
- Edge Preparation: Precision-honed T-land for burr-free groove formation
- Thermal Stability: Stable performance up to 400°C without oxidation degradation
- Primary Advantage: Mirror-finish surface quality on groove walls and floors
Grade Comparison Matrix
| Grade | Coating | Best For | Speed Range |
|---|---|---|---|
| KW10 | Uncoated | Steel, Cast Iron, Non-Ferrous | Low–Moderate |
| KW20 | Uncoated | Hardened Steel, Abrasive Cast Iron | Low |
| PR930 | PVD Coated | Stainless Steel, High-Temp Alloys | Moderate–High |
| CA310 | CVD Coated | General Steel, High-Speed Turning | High |
Chipbreaker Profile
The GVFR450C utilizes a C chipbreaker geometry specifically designed for face grooving operations. The rake face is engineered to direct chips upward and away from the groove floor, preventing chip packing in the recess and protecting finished groove surfaces. This profile ensures controlled chip formation even at low depths of cut common in precision face grooving.
- Chipbreaker Type: C (Face Grooving Profile)
- Rake Angle: Neutral to slightly positive for steel and cast iron
- Flank Relief: Optimized for face groove wall accuracy
- Chip Flow: Upward and outward evacuation from recess
- Edge Condition: Micro-honed to prevent burr formation on groove edges
Recommended Applications & Workpiece Materials
The KW10 substrate and uncoated edge make the GVFR450C particularly effective on materials where edge sharpness directly correlates with surface finish quality in face grooving operations. Recommended workpiece materials include:
- Carbon & Alloy Steels (up to 35 HRC) — Excellent groove finish and tool life
- Stainless Steels (304, 316, 430 series) — Reduced work-hardening tendency due to sharp edge
- Cast Iron (Gray, Ductile) — Stable cutting with minimal edge chipping
- Non-Ferrous Metals (Aluminum, Brass, Copper) — Mirror finish achievable without built-up edge
- Titanium Alloys (Ti-6Al-4V) — Suitable for low-speed precision face grooving with adequate coolant
Application Map by Operation
| Operation Type | Suitability | Notes |
|---|---|---|
| Face Grooving | ★★★★★ Excellent | Primary application; perpendicular to workpiece axis |
| Recessing / Counterboring | ★★★★☆ Very Good | Compatible with radial plunge cycles |
| External Grooving | ★★☆☆☆ Limited | Not recommended; use standard GVF grooving inserts |
| Internal Grooving | ★☆☆☆☆ Not Suitable | Geometry not designed for internal applications |
Recommended Cutting Conditions
| Workpiece Material | Cutting Speed Vc (m/min) | Feed f (mm/rev) | Max Depth of Cut (mm) |
|---|---|---|---|
| Mild Steel (C<0.3%) | 80 – 120 | 0.05 – 0.15 | Up to insert length limit |
| Alloy Steel (30–35 HRC) | 60 – 90 | 0.05 – 0.12 | Up to insert length limit |
| Stainless Steel (304/316) | 50 – 80 | 0.05 – 0.10 | Up to insert length limit |
| Gray Cast Iron (HB 180–220) | 60 – 100 | 0.08 – 0.18 | Up to insert length limit |
| Aluminum Alloy (6061-T6) | 150 – 250 | 0.08 – 0.20 | Up to insert length limit |
| Titanium Alloy (Ti-6Al-4V) | 15 – 25 | 0.05 – 0.08 | Up to 10 mm |
Note: Values are starting recommendations. Optimize based on machine rigidity, coolant delivery, and workpiece setup. For face grooving, ensure tool overhang is minimized to prevent chatter.
Operating Guidelines
- Toolholder Selection: Use GVF-compatible face grooving holders with precise pocket tolerances (±0.01 mm) and adequate radial reach for the required groove diameter.
- Insert Seating: Ensure the insert sits fully in the pocket without debris. Torque clamping screw to 2.5–3.0 N·m; do not overtighten.
- Coolant Recommendation: High-pressure coolant directed at the cutting zone is strongly recommended for steel and stainless steel to prevent chip packing in the recess. For cast iron and aluminum, flood coolant or dry machining is acceptable.
- Depth of Cut Strategy: Use multiple radial passes for deep face grooves; do not exceed 1.5× insert width per pass to prevent breakage.
- Indexing: When edge degradation is detected (visible flank wear >0.05 mm or groove wall burrs), index to the second cutting edge. Discard insert if both edges are exhausted.
- Workpiece Setup: Ensure the workpiece face is perpendicular to the spindle axis within 0.02 mm to maintain uniform groove depth across the diameter.
Toolholder Compatibility
The GVFR450C is designed to seat in standard GVF series face grooving toolholders. Compatible holder families include:
- Kyocera GVF-F Face Grooving Holders (matching width and radial reach)
- Kyocera GVF-FR Face Grooving / Recessing Holders
- ISO 1832 Type G (Rectangular Grooving) compliant pockets
- Clamp systems: Lever-lock or top-screw clamp depending on holder series
Verify holder pocket geometry (width, thickness, and seat angle) matches insert specifications before mounting. Incompatible holders may cause vibration, poor groove accuracy, and insert fracture.
