Kyocera FMN3 KW10 Grade Uncoated Carbide, Indexable Grooving Insert
Product Overview
The FMN KW10 Indexable Grooving Insert from Kyocera Precision Tools is engineered for cnc turning operations. produces superior surface integrity on critical components. optimized edge preparation extends tool life. Manufactured in Japan to exacting ISO standards, this insert superior chip evacuation in enclosed cavities.
Ideal for high-volume production environments, the KW10 grade carbide substrate offers an optimal balance of hardness, toughness, and thermal stability for demanding machining applications.
ISO Designation Breakdown
Understanding the insert designation ensures correct selection and compatibility:
| ISO Designation: FMN3 | |
|---|---|
| Shape (1st Letter) | T — 60 Degree Triangle (3 cutting edges) |
| Clearance Angle (2nd) | N — Standard clearance |
| Tolerance Class (3rd) | G — Precision-ground |
| Hole/Chipbreaker (4th) | N/A — Standard |
| Inscribed Circle (Size) | N/A |
| Thickness | N/A |
| Corner Radius | N/A |
Engineering Dimensions & Geometry
| Dimensional Specifications | |
|---|---|
| Shape | 60 Degree Triangle |
| Included Angle | ° |
| Inscribed Circle (IC) | |
| Thickness (T) | |
| Corner Radius (R) | |
| Number of Cutting Edges | 3 |
| Hand | Neutral |
The 60 degree triangle geometry with 3 usable edges provides moderate edge stability, making it the preferred choice for general turning and boring. The corner radius balances surface finish quality with edge strength for cnc turning.
Grade Details — Key Grade Characteristics
| KW10 Uncoated Carbide Specifications | |
|---|---|
| Substrate Composition | fine-grain tungsten carbide |
| Binder / Matrix | cobalt |
| ISO Application Group | K10 |
| Hardness | 91.5 HRA |
| Transverse Rupture Strength | 2.5 GPa |
| Coating | Uncoated |
| Color Code | grey |

- cast iron, non-ferrous metals, titanium alloys, plastics, wood composites
Primary operations include: CNC Turning.
Application Map by Operation
| Operation | Suitability | Notes |
|---|---|---|
| External Turning | ★★★★☆ Very Good | Compatible via standard toolholder setup |
| Internal Turning | ★★☆☆☆ Limited | Not recommended — select alternative geometry |
| Boring | ★★☆☆☆ Limited | Not recommended — select alternative geometry |
| Facing | ★★☆☆☆ Limited | Not recommended — select alternative geometry |
| Chamfering | ★★☆☆☆ Limited | Not recommended — select alternative geometry |
| Copying | ★★☆☆☆ Limited | Not recommended — select alternative geometry |
| Back Boring | ★★☆☆☆ Limited | Not recommended — select alternative geometry |
| Grooving | ★★☆☆☆ Limited | Not recommended — select alternative geometry |
| Milling | ★★☆☆☆ Limited | Not recommended — select alternative geometry |
Recommended Cutting Conditions
| Starting Parameters for KW10 | |
|---|---|
| Cutting Speed (Vc) | 80–250 m/min |
| Feed Rate (f) | 0.05–0.25 mm/rev |
| Depth of Cut (ap) | 0.1–2.0 mm |
| Coolant Recommendation | Wet cutting with water-soluble coolant recommended |
| Workpiece Condition | Continuous or lightly interrupted cuts |
Parameters are starting recommendations. Optimize based on machine rigidity, workpiece condition, and surface finish requirements. Reduce speed by 15–20% for interrupted cuts or scale formation.
Operating Guidelines
- Ensure toolholder pocket is clean and free of burrs before insert seating.
- Torque clamping screw to manufacturer specification (typically 2.5–4.5 N·m for M2.5–M4 screws).
- Use precision collet or hydraulic chuck for boring bars to minimize runout.
- For uncoated carbide: use adequate coolant flow to prevent built-up edge on aluminum and titanium.
- Inspect insert after initial passes; adjust feed if chip color indicates excessive heat.
- Store inserts in original packaging away from moisture and corrosive atmospheres.
Toolholder Compatibility
The FMN is compatible with the following Kyocera and standard ISO toolholders:
FMN dedicated grooving toolholders (external/internal)
Verify pocket angle (typically ° for 60 degree triangle inserts) and clamp type (lever-lock, pin-lock, or top-clamp) match your holder design. Contact Kyotow.com technical support for holder selection assistance.
