| PR1225 | ★★★★☆ | ★★★★☆ | High-Speed CNC |
| PR1225 | ★★★☆☆ | ★★★★★ | Interrupted cuts, roughing |
| PR1725 | ★★★★★ | ★★★☆☆ | High-speed finishing |
Chipbreaker Profile
The TG-Type chipbreaker geometry is optimized for copper machining. It features a precisely ground rake face and controlled land width to ensure efficient chip curling and breakage, preventing chip packing and extending tool life.
- Rake Angle: 8° – 12° (variable)
- Land Width: 0.15 mm
- Chip Pocket Depth: 0.08 mm
- Recommended Chip Load: 0.08 – 0.15 mm/rev
Recommended Applications & Workpiece Materials
| Material Group | ISO Code | Machinability |
|---|---|---|
| Carbon Steel | P.1 – P.3 | Excellent |
| Alloy Steel | P.4 – P.6 | Very Good |
| Stainless Steel | M.1 – M.3 | Good |
| Cast Iron | K.1 – K.3 | Excellent |
| Aluminum Alloy | N.1 – N.3 | Good (with polish) |
Application Map by Operation
- Through-Hole Drilling: Ideal for depths up to 3XD×D with peck cycle
- Blind-Hole Drilling: Excellent chip evacuation with coolant-through option
- High-Speed Machining: Stable up to 120 m/min on carbon steel
- Micro-Drilling: Suitable for precision holes in medical and electronics
- Ramp/Helical Milling: Capable of light milling operations at reduced feed
Recommended Cutting Conditions
| Material | Vc (m/min) | fn (mm/rev) | Coolant |
|---|---|---|---|
| Carbon Steel | 120 | 0.18 | Emulsion / MQL |
| Alloy Steel | 102.0 | 0.162 | Emulsion |
| Stainless Steel | 84.0 | 0.144 | High-Pressure |
| Cast Iron | 132.0 | 0.198 | Dry / Air Blast |
| Aluminum | 180.0 | 0.216 | MQL / Air |
Operating Guidelines
- Always use rigid toolholding (hydraulic or shrink-fit) to minimize runout
- Ensure spindle runout is < 5 μm at the tool tip
- Use constant peck depth of 1–1.5×D for depths > 3×D
- Maintain coolant concentration between 8–12% for water-based coolants
- Inspect cutting edges after every 50 holes in abrasive materials
- Replace drill when flank wear exceeds 0.15 mm or chipping is visible
Toolholder Compatibility
| Holder Type | Shank Diameter | Clamping Force |
|---|---|---|
| Hydraulic Chuck | 2.0 mm | High (rigid) |
| Shrink-Fit Holder | 2.0 mm | Very High (best) |
| ER Collet (ER16/ER20) | 2.0 mm | Medium |
| Milling Chuck | 2.0 mm | High |
