Kyocera TKF16R200S16DR KW10 Grade Uncoated Carbide, Indexable Cut-Off Insert
Product Overview
The Kyocera TKF16R200S16DR KW10 Grade Uncoated Carbide Cut-Off Insert (Manufacturer Part Number: TWE16262) is a precision-engineered indexable insert designed for parting off. Manufactured in Japan from premium sub-micron carbide, this precision cut-off blade is engineered for clean parting-off with minimal burr formation. The KW10 grade provides a sharp, uncoated cutting edge ideal for mirror-finish machining of aluminum, copper, cast iron, and titanium alloys.

Chipbreaker Profile
The S-type chipbreaker for cut-off applications features a near-zero rake angle with a precision-ground chip groove along the top face. The geometry is optimized for straight, stable cutting with minimal deflection. The narrow land width ensures clean parting surfaces while the groove directs chips outward to prevent packing in the groove.
Recommended Applications & Workpiece Materials

Recommended Cutting Conditions
Starting parameters for KW10 grade. Adjust based on machine rigidity, workpiece condition, and required surface finish:
| Material | Vc (m/min) | fn (mm/rev) | DOC (mm) |
|---|---|---|---|
| Aluminum | 150 - 300 | 0.03 - 0.08 | Max blade width |
| Copper | 120 - 250 | 0.03 - 0.06 | Max blade width |
| Cast Iron | 60 - 120 | 0.05 - 0.10 | Max blade width |
Operating Guidelines
- Coolant: Flood coolant recommended for aluminum and copper to prevent built-up edge. Dry cutting acceptable for cast iron. Use high-pressure coolant for titanium alloys.
- Toolholder: Ensure holder pocket is clean and undamaged. Use correct torque when clamping (typically 2.5 - 3.5 N·m for M2.5 screws).
- Runout: Maintain radial runout below 0.01 mm at the cutting edge for optimal surface finish and tool life.
- Entry: Use ramp or helical entry for grooving and drilling operations. Avoid plunging directly into solid material at full depth.
- Edge Inspection: Inspect inserts after 30 minutes of cutting for wear patterns. Replace when flank wear exceeds 0.15 mm or when chipping is observed.
- Storage: Store inserts in original packaging away from moisture and direct sunlight. Handle with gloves to prevent corrosion from skin oils.
