CNGG432RA3 KW10 Grade Uncoated Carbide, Indexable Turning Insert For Boring, External Turning, Facing, Internal Facing
Product Overview
The CNGG120408R-A3 is a premium-grade indexable turning insert from Kyocera Precision Tools, engineered for boring, external turning, facing, internal facing. Featuring a 80 degree diamond geometry with 4 usable cutting edges, this uncoated carbide insert delivers exceptional surface finish, dimensional accuracy, and extended tool life in demanding CNC turning environments.
Manufactured in Japan from ultra-fine grain tungsten carbide (K10 equivalent), the KW10 substrate offers outstanding hardness and wear resistance for machining non-ferrous metals, cast iron, titanium alloys, and non-metallic materials. The A3 chipbreaker ensures reliable chip control across a wide range of feeds and depths of cut.

Chipbreaker Profile
A3 Chipbreaker Profile: The A3 geometry features a precision-ground chipbreaker groove optimized for boring operations. It produces tightly curled chips that evacuate safely from the cutting zone, reducing heat buildup and improving surface integrity. The sharp cutting edge and positive rake design minimize cutting forces, making it ideal for finishing to medium machining of non-ferrous materials.
- Chipbreaker Code: A3
- Recommended Feed Range: 0.05–0.30 mm/rev
- Depth of Cut: 0.10–2.00 mm
- Chip Control: Excellent for continuous and light interrupted cuts
Recommended Applications & Workpiece Materials
- Primary Operations: Boring, External Turning, Facing, Internal Facing
- Workpiece Materials: non-ferrous metals, cast iron, titanium alloys, aluminium, copper, plastics, wood, ceramics
- Industry Sectors: Aerospace, automotive, medical devices, general precision engineering, electronics
- Process Types: Finish turning, semi-finish turning, facing, boring, chamfering, copying
Application Map by Operation
| Operation | Suitability | Notes |
|---|---|---|
| Boring | ✓ Recommended | Excellent – precise diameter control and surface finish |
| External Turning | ✓ Recommended | Excellent – primary application for finish to medium cuts |
| Facing | ✓ Recommended | Excellent – clean face generation with minimal witness marks |
| Internal Facing | ✓ Recommended | Good – recess and shoulder facing |
Recommended Cutting Conditions
| Parameter | Range | Optimal |
|---|---|---|
| Cutting Speed (Vc) | 150–400 m/min | 250 m/min |
| Feed Rate (f) | 0.05–0.30 mm/rev | 0.15 mm/rev |
| Depth of Cut (ap) | 0.10–2.00 mm | 0.50 mm |
| Coolant | Wet or Dry | Wet (flood) for aluminium |
Operating Guidelines
- Workpiece Security: Ensure rigid clamping and minimal overhang to prevent chatter during finishing passes.
- Toolholder Selection: Use precision toolholders with run-out ≤ 0.01 mm for best surface finish.
- Coolant Recommendation: Water-soluble coolant at 6–8% concentration is recommended for aluminium and titanium to prevent built-up edge.
- Edge Preparation: The insert is supplied with a sharp, honed edge (ER) ready for immediate use; no additional honing required.
- Storage: Store in original packaging away from moisture and corrosive atmospheres to preserve edge integrity.
- Inspection: Visually inspect each edge under magnification before use; discard if micro-chipping exceeds 0.05 mm.
Toolholder Compatibility
This 80 degree diamond insert is compatible with standard ISO toolholders designed for CNGG inserts. Ensure the toolholder pocket matches the insert thickness (3/16") and hand (Right-Hand).
- Compatible Holder Styles: CNGG turning holders, boring bars, facing tools
- Clamping Systems: Lever-lock, pin-lock, and screw-clamp (depending on holder design)
- Insert Hand: Right-Hand – verify holder pocket orientation before installation
- Shim Requirements: Use original Kyocera shims of matching thickness for optimal seat contact
