Kyocera GVFR100AR KW10 Grade Uncoated Carbide Indexable Grooving Insert
Product Overview
The Kyocera GVFR100AR is a KW10-grade uncoated carbide indexable insert designed for grooving. Manufactured in Japan under ISO 9001:2015 quality standards, this insert combines an ultra-fine grain substrate with precision-ground geometry to deliver superior surface quality, efficient chip breaking, and maximum insert longevity in demanding CNC environments.
Engineered for right-hand applications, the GVFR100AR features a sharp ground cutting edge ideal for grooving and parting. Each insert provides reliable performance, making it a cost-effective solution for high-volume production shops.

Recommended Applications & Workpiece Materials
The GVF series grooving insert excels in precision external grooving, cut-off, and parting operations. The uncoated KW10 substrate provides the sharpness required for non-ferrous materials and cast iron.
- Cast Iron: Grey cast iron (FC250, FC300), ductile iron (FCD500), excellent for finish grooving
- Non-Ferrous Metals: Aluminum alloys (6061-T6, 7075), brass (C36000), copper — superior surface finish
- Titanium Alloys: Ti-6Al-4V, Ti-5Al-2.5Sn — stable cutting at moderate speeds
- Plastics & Composites: PEEK, GFRP, CFRP — clean cuts without delamination
Application Map by Operation
| Operation | Suitability | Remarks |
|---|---|---|
| External Grooving | ★★★★★ | Primary application, optimal chip control |
| Cut-Off / Parting | ★★★★☆ | Excellent with rigid setup |
| Face Grooving | ★★★☆☆ | Requires specialized holder |
| Internal Grooving | ★★☆☆☆ | Not recommended — external only |
Recommended Cutting Conditions
Parameters below serve as starting points. Optimize based on machine rigidity, coolant delivery, and workpiece condition:
| Material | Vc (m/min) | Feed (mm/rev) | Depth (mm) | Coolant |
|---|---|---|---|---|
| Grey Cast Iron | 80–150 | 0.05–0.12 | ≤1.00 | Dry / Compressed air |
| Aluminum Alloy | 200–400 | 0.03–0.08 | ≤1.00 | Water-soluble / MQL |
| Brass / Bronze | 100–250 | 0.04–0.10 | ≤1.00 | Dry preferred |
| Titanium Alloy | 25–50 | 0.02–0.05 | ≤1.00 | High-pressure coolant |
Operating Guidelines
- Tool Setup: Ensure grooving toolholder center height is within ±0.02 mm of spindle centerline to prevent chatter in deep grooves.
- Edge Inspection: Visually inspect insert cutting edge under 10× magnification before installation. Replace if micro-chipping exceeds 0.05 mm.
- Workpiece Runout: Maintain TIR below 0.01 mm at the cutting zone. Excessive runout accelerates localized wear on the single cutting lip.
- Coolant Strategy: For cast iron and brass, dry machining is preferred to avoid thermal shock. For titanium, apply high-pressure coolant (70+ bar) directed at the cutting edge.
- Speed Ramping: Start at 70% of recommended Vc for the first 5 parts, then increase to 100% once tool wear stabilizes.
- Insert Indexing: Rotate to fresh edge every 45–60 minutes of cutting time or when flank wear (VB) reaches 0.15 mm, whichever occurs first.
- Storage: Keep inserts in original packaging until use. Avoid contact between cutting edges during storage to prevent chipping.
Toolholder Compatibility
| Holder Series | Compatible Size | Holder Type | Clamp System |
|---|---|---|---|
| KGD-J | 1.0 mm | External grooving | Top clamp + pin |
| KGD-L | 1.0 mm | External grooving, long reach | Top clamp + pin |
| KGB | 1.0 mm | Cut-off / Parting | Wedge clamp |
Mounting Notes: Use torque wrench set to 2.5 N·m for clamp screws. Verify holder pocket cleanliness with compressed air before insert seating.
