Recommended Applications & Workpiece Materials
The KDA0630X05S080C with S080C grade is specifically recommended for the following materials:
Carbon steels (C45, C60), alloy steels (4140, 4340), stainless steels (304, 316L), and cast irons (GG25, GGG40).
Application Map by Operation
| Operation | Suitability | Notes |
|---|---|---|
| Centering | Excellent | Optimal for 6.3mm centering operations |
| Drilling | Good | Suitable for standard drilling applications |
| Chamfering | Good | Suitable for standard chamfering applications |
| Spot-facing | Suitable | Suitable for standard spot-facing applications |
Recommended Cutting Conditions
| Parameter | Range | Optimal |
|---|---|---|
| Cutting Speed (Vc) | 80 - 150 m/min | 80 - 115 m/min |
| Feed Rate (f) | 0.10 - 0.25 mm/rev | 0.18 mm/rev |
| Drilling Depth | 2×D - 5×D | 3×D |
| Coolant | Emulsion / MQL / Dry | High-pressure internal coolant (70+ bar) |
Operating Guidelines
- Run-in Period: Reduce cutting speed by 20% for the first 10 holes to stabilize the cutting edge.
- Chip Evacuation: Ensure adequate coolant flow (minimum 15 L/min) to prevent chip recutting and insert fracture.
- Toolholder Runout: Maintain TIR below 0.01 mm at the tool tip for optimal hole accuracy and surface finish.
- Peck Drilling: For depths exceeding 3×D, use peck cycles of 1×D to 1.5×D with full retraction for chip clearing.
- Edge Inspection: Inspect insert seating surface and toolholder pocket every 50 holes for debris or wear.
- Replacement Criteria: Replace insert when flank wear exceeds 0.3 mm, or when surface roughness (Ra) exceeds 1.6 μm.
