Kyocera ZCMT200608 KW10 Grade Uncoated Carbide, Indexable Drilling Insert
Product Overview
The Kyocera ZCMT200608 KW10 Grade Uncoated Carbide Drilling Insert (Manufacturer Part Number: TWE65043) is a precision-engineered indexable insert designed for drilling. Manufactured in Japan from premium sub-micron carbide, this irregular-profile drilling insert is engineered for stable hole-making in cast iron and non-ferrous materials. 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 DRZ-type chipbreaker is a specialized drilling profile with a dual-rake geometry optimized for center and peripheral cutting edges. The positive rake angle at the center reduces thrust forces, while the peripheral land provides edge stability. This profile ensures balanced chip formation across the drill diameter for consistent hole quality.
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 | 80 - 150 | 0.10 - 0.25 | 0.5D - 2.0D |
| Cast Iron | 40 - 80 | 0.12 - 0.30 | 0.5D - 2.0D |
| Titanium | 15 - 40 | 0.08 - 0.15 | 0.5D - 1.5D |
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.
