Grade Details – Key Grade Characteristics
The PR1535 grade utilizes a nano-layered PVD coating technology deposited on a sub-micron grain carbide substrate. This combination provides:
- Superior Wear Resistance: Multi-layer TiAlN coating minimizes crater and flank wear under high cutting temperatures.
- Enhanced Edge Stability: Optimized substrate toughness prevents chipping and micro-fractures in interrupted cuts.
- Thermal Shock Resistance: Excellent performance in wet and MQL (Minimum Quantity Lubrication) environments.
- Low Friction Coefficient: Reduces built-up edge (BUE) when machining sticky materials like stainless steel.
Grade Comparison Matrix
| Grade | Coating | Wear Resistance | Toughness | Best For |
|---|---|---|---|---|
| PR1535 | TiAlN PVD | ★★★★☆ | ★★★★☆ | General Purpose |
| PR1225 | TiSiN PVD | ★★★★★ | ★★★☆☆ | Hardened Steel |
| CA025P | TiCN PVD | ★★★☆☆ | ★★★★★ | Interrupted Cuts |
Chipbreaker Profile
The SGS series features a proprietary variable helix flute design with polished rake surfaces and a reinforced core geometry. The chipbreaker layout ensures:
- Efficient chip evacuation in deep-hole drilling (up to 3×D without pecking)
- Reduced cutting forces and spindle load
- Stable chip formation across variable feed rates
- Minimized burr formation at hole exit
Recommended Applications & Workpiece Materials
Ideal for precision drilling in the following material groups:
- P-Steels: Carbon steel, alloy steel, tool steel (up to 35 HRC)
- M-Stainless: Austenitic and martensitic stainless steels (303, 304, 316, 410)
- K-Cast Iron: Gray cast iron, ductile iron, compacted graphite iron
- N-Aluminum: Wrought aluminum alloys (with adjusted speeds)
Application Map by Operation
| Operation | Suitability | Max Depth | Notes |
|---|---|---|---|
| Through-Hole Drilling | Excellent | 3×D | Standard application |
| Blind-Hole Drilling | Excellent | 2.5×D | Use reduced feed at bottom |
| Spot Drilling | Good | 0.5×D | Self-centering point |
| Counterboring | Fair | 1×D | Reduce speed by 20% |
Recommended Cutting Conditions
| Workpiece Material | Cutting Speed (Vc) | Feed (f) | Coolant |
|---|---|---|---|
| Carbon Steel | 60–90 m/min | 0.08–0.15 mm/rev | Wet / MQL |
| Alloy Steel | 50–80 m/min | 0.07–0.12 mm/rev | Wet / MQL |
| Stainless Steel | 40–60 m/min | 0.06–0.10 mm/rev | Wet (high pressure) |
| Cast Iron | 70–100 m/min | 0.10–0.18 mm/rev | Dry / Wet |
| Aluminum | 100–150 m/min | 0.10–0.20 mm/rev | MQL / Air |
Operating Guidelines
- Runout: Ensure spindle runout is less than 0.01 mm to maximize tool life and hole accuracy.
- Pecking: For depths exceeding 3×D, use a peck cycle with 1×D depth per peck and full retract to break chips.
- Coolant: Maintain coolant concentration at 6–8% for emulsion; use through-spindle coolant when available for best chip evacuation.
- Entry Angle: Use a chamfer or pilot hole when drilling on angled surfaces greater than 10° to prevent walk.
- Tool Life: Monitor flank wear (VB). Regrind or replace when VB exceeds 0.3 mm or when hole tolerance degrades.
Toolholder Compatibility
This solid carbide drill is compatible with standard collet chucks, hydraulic chucks, and shrink-fit holders with the following requirements:
- Collet Chuck: ER16, ER20, or ER25 (depending on shank diameter)
- Clamping Force: Minimum 50 Nm torque on collet nut
- Runout at 3×D: ≤ 0.015 mm TIR
- Tool Overhang: Keep to minimum practical length to reduce deflection
