Chipbreaker Profile
The Kyocera 12,0 features a Standard Chipbreaker Profile specifically optimized for 12.0mm diameter drilling. This geometry provides:
- Controlled Chip Formation: Curved rake face design ensures tight chip curling for reliable evacuation
- Reduced Cutting Forces: standard land width minimizes friction and heat generation
- Enhanced Edge Stability: Polished flank surfaces prevent built-up edge (BUE) on sticky materials
- Optimized for Through-Hole & Blind-Hole: Chipbreaker geometry suited for both drilling applications
| Chipbreaker Parameter | Value |
|---|---|
| Rake Angle (γ) | 13° |
| Clearance Angle (α) | 9° |
| Chipbreaker Width | 3.0 mm |
| Chipbreaker Depth | 0.72 mm |

Application Map by Operation
| Operation Type | Suitability | Max Depth (D) | Notes |
|---|---|---|---|
| Through-Hole Drilling | ★★★★★ | 5×D | Optimal chip evacuation |
| Blind-Hole Drilling | ★★★★☆ | 3×D | Use peck cycle recommended |
| Stack Drilling | ★★★☆☆ | 2×D | Clamp workpiece securely |
| Cross-Hole Drilling | ★★☆☆☆ | 1.5×D | Reduce feed by 30% |
| Micro-Drilling | ★☆☆☆☆ | N/A | Not applicable for this size |
Recommended Cutting Conditions
| Workpiece Material | Cutting Speed Vc (m/min) | Feed fn (mm/rev) | RPM (min⁻¹) |
|---|---|---|---|
| Low-Alloy Steel (<30 HRC) | 59 | 0.096 | 1,565 |
| Stainless Steel (304/316) | 43 | 0.081 | 1,140 |
| Aluminum Alloy (6061/7075) | 112 | 0.156 | 2,970 |
| Cast Iron (Grey 250) | 53 | 0.106 | 1,408 |
| Titanium Alloy (Ti-6Al-4V) | 30 | 0.065 | 798 |
Note: Values are starting recommendations. Adjust based on machine rigidity, coolant delivery, and workpiece fixturing.
Operating Guidelines
- Coolant: High-pressure coolant (≥70 bar) is strongly recommended for optimal chip evacuation and tool life. Use water-soluble coolant with 8-10% concentration.
- Peck Drilling: For depths exceeding 3×D, implement a peck cycle with retract of 0.5-1×D to clear chips and reduce heat buildup.
- Entry Angle: Ensure perpendicular entry (±1°) or use a spot drill to prevent walk and ensure positional accuracy.
- Speed/Feed Ramp: Reduce feed by 50% for the first 1-2mm of engagement, then ramp to full feed over 0.5 seconds.
- Tool Life Monitoring: Expected tool life is 110 minutes under optimal conditions. Monitor for flank wear >0.2mm or chipping on cutting edges.
- Re-sharpening: Not recommended. These solid carbide drills are designed as disposable precision tools for consistent performance.
Toolholder Compatibility
| Holder Type | Shank Diameter | Clamping Force | Runout Tolerance |
|---|---|---|---|
| Hydraulic Chuck | 12.5 mm | High | ≤3 µm |
| ER Collet (ER16/ER20) | 12.5 mm | Medium | ≤5 µm |
| Shrink Fit Holder | 12.5 mm | Very High | ≤2 µm |
