Kyocera NDCW322FRX KW10 Grade Uncoated Carbide, Indexable Milling Insert
Product Overview
The Kyocera NDCW322FRX is a KW10-grade uncoated carbide parallelogram milling insert designed for facing, shouldering, slotting. Manufactured in Japan under ISO 9001:2015 quality standards, this insert combines an ultra-fine grain substrate with the FR chipbreaker geometry to deliver excellent surface integrity, optimized chip flow, and prolonged tool durability in demanding CNC milling environments.
Engineered for right-hand applications, the NDCW322FRX features a 55° included angle with 7° clearance, making it ideal for facing, 90° shouldering, and slotting operations. Each insert provides 2 usable cutting edges, offering cost-effective performance for high-volume production shops.

Recommended Applications & Workpiece Materials
The DMC series parallelogram milling insert excels in facing, shouldering, and slotting operations. The KW10 substrate provides the hardness and wear resistance needed for cast iron and non-ferrous alloys at elevated cutting speeds.
- Cast Iron: Grey cast iron (FC250, FC300), ductile iron (FCD500) — stable milling at high speeds with excellent surface finish
- Non-Ferrous Metals: Aluminum alloys (6061-T6, 7075), brass (C36000), copper — superior chip control and surface integrity
- Titanium Alloys: Ti-6Al-4V, Ti-5Al-2.5Sn — controlled cutting forces prevent work-hardening in slotting
- Plastics & Composites: PEEK, GFRP, CFRP — clean shearing action without delamination
Application Map by Operation
| Operation | Suitability | Remarks |
|---|---|---|
| Facing | ★★★★★ | Primary application — excellent surface finish |
| Shouldering | ★★★★★ | 90° wall capability with 55° insert |
| Slotting | ★★★★☆ | Full slotting up to 1×D depth |
| Ramping | ★★★☆☆ | Limited by 7° clearance angle |
| Helical Interpolation | ★★★☆☆ | Possible with reduced parameters |
Recommended Cutting Conditions
Parameters below serve as starting points. Optimize based on machine rigidity, coolant delivery, and workpiece condition:
| Material | Vc (m/min) | fz (mm/tooth) | ap (mm) | Coolant |
|---|---|---|---|---|
| Grey Cast Iron | 80–150 | 0.08–0.18 | 1.0–3.0 | Dry / Compressed air |
| Aluminum Alloy | 200–400 | 0.05–0.12 | 1.0–2.5 | Water-soluble / MQL |
| Brass / Bronze | 100–250 | 0.06–0.15 | 1.0–2.5 | Dry preferred |
| Titanium Alloy | 25–50 | 0.04–0.10 | 0.5–1.5 | High-pressure coolant |
Operating Guidelines
- Tool Setup: Ensure cutter body runout is below 0.01 mm TIR at the insert pocket. Excessive runout causes uneven wear and chatter.
- Edge Inspection: Inspect insert cutting edge under 10× magnification before installation. Replace if chipping exceeds 0.05 mm or flank wear (VB) exceeds 0.15 mm.
- Workpiece Fixturing: Rigid clamping is essential. Minimize overhang and use support for thin-walled workpieces to prevent vibration.
- 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 zone.
- 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 reaches 0.15 mm.
- Storage: Keep inserts in original packaging until use. Avoid contact between cutting edges during storage.
