Grade Details – Key Grade Characteristics
Grade PR1535 is a premium sub-micron grain carbide substrate with advanced PVD multi-layer coating technology. Engineered specifically for small-diameter drilling applications, this grade offers:
- Micro-grain structure: Sub-0.5 μm WC grain size for superior edge sharpness and wear resistance.
- PVD Coating: TiAlN-based multi-layer coating provides exceptional thermal stability up to 900°C and reduced built-up edge formation.
- High hardness: HRA 92.5 for maintained cutting edge integrity at elevated speeds.
- Optimized cobalt binder: 8% Co content balances toughness and hardness for intermittent cutting conditions.
- Low friction coefficient: Minimizes heat generation and extends tool life by up to 40% compared to uncoated substrates.

| Flute Form | Parabolic with polished surface (Ra 0.1 μm) |
| Chipbreaker Type | Micro-groove (0.05 mm depth) |
| Chip Curl Radius | 1.5 – 2.0 mm |
Recommended Applications & Workpiece Materials
- Carbon Steels: C35, C45, C60 – Excellent chip control and surface finish quality.
- Alloy Steels: 42CrMo4, 16MnCr5, 20MnCr5 – Ideal for case-hardened and tempered components.
- Stainless Steels: 304, 316, 430 – Reduced work-hardening tendency due to optimized point geometry.
- Cast Iron: GGG40, GGG50 – Suitable for short-chipping grey and nodular cast irons.
- Aluminum Alloys: AlSi10Mg, AlCuMgPb – Polished flutes prevent material adhesion.
- Titanium Alloys: Ti-6Al-4V – Reduced heat buildup enables controlled drilling depths up to 3×D.
Application Map by Operation
| Operation Type | Suitability | Max Depth | Notes |
| Through-hole Drilling | ★★★★★ Excellent | 5×D | Optimal chip evacuation |
| Blind-hole Drilling | ★★★★☆ Very Good | 3×D | Use peck cycle for depths >2×D |
| Cross-hole Drilling | ★★★☆☆ Good | 2×D | Reduce feed by 20% |
| Stack Drilling | ★★★★☆ Very Good | — | Ensure clamping rigidity |
| Enlarging / Reaming | ★★☆☆☆ Fair | 1×D | Not recommended as primary use |
Recommended Cutting Conditions
| Workpiece Material | Cutting Speed Vc (m/min) | Spindle Speed n (rpm) | Feed f (mm/rev) | Feed Rate Vf (mm/min) |
| Carbon Steel (C35) | 80 – 100 | 11,071 – 13,838 | 0.0690 | 763.9 – 954.9 |
| Alloy Steel (42CrMo4) | 70 – 90 | 9,687 – 12,454 | 0.0690 | 668.4 – 859.4 |
| Stainless Steel (304) | 60 – 80 | 8,303 – 11,042 | 0.0552 | 458.3 – 613.0 |
| Aluminum Alloy (AlSi10Mg) | 120 – 150 | 16,607 – 20,758 | 0.0828 | 1375.1 – 1718.9 |
| Cast Iron (GGG50) | 90 – 110 | 12,454 – 15,222 | 0.0690 | 859.4 – 1050.4 |
Note: Values are starting recommendations. Adjust based on machine rigidity, coolant concentration, and workpiece clamping conditions. For depths exceeding 3×D, reduce Vc by 15% and use peck drilling cycle.
Operating Guidelines
- Run-out Tolerance: Ensure spindle TIR ≤ 5 μm. Excessive run-out dramatically reduces tool life in micro-diameter drilling.
- Coolant Supply: Use high-pressure coolant (min. 20 bar) with 6–8% soluble oil emulsion for steels. For aluminum, use neat oil or synthetic coolant to prevent built-up edge.
- Peck Drilling: For holes deeper than 3×D, employ a peck cycle with 1×D peck depth and 0.3×D retract to break chips.
- Entry Angle: Drill perpendicular to surface (±1°). Use spot drilling or centering for inclined entry angles > 3°.
- Pre-drilling: Not required for standard through-holes up to 3×D depth. For cross-holes, reduce feed by 20% at intersection.
- Tool Overhang: Minimize overhang to 4×D maximum. Use collet chucks or hydraulic holders for best results.
- Re-sharpening: Not recommended due to micro-diameter geometry complexity. Replace tool when flank wear exceeds 0.05 mm.
Toolholder Compatibility
| Holder Type | Recommended Model | Clamping Range | Application Notes |
| ER Collet Chuck | ER11, ER16 (AA precision) | 1.0 – 3.0 mm | Most economical; ensure collet accuracy ≤ 10 μm |
| Hydraulic Expansion Chuck | HSK-A63 Hydro | 3.0 – 6.0 mm | Best damping; ideal for high-speed machining |
| Shrink Fit Holder | HSK-E40 Shrink | 3.0 – 6.0 mm | Highest run-out accuracy (≤ 3 μm) |
| Weldon Side-Lock | Not Recommended | — | Risk of shank deformation on micro-tools |
