Grade Details — Key Grade Characteristics
PR1535 MEGACOAT NANO delivers exceptional performance in large-diameter drilling where heat generation and chip evacuation are challenging. The coating's thermal stability extends tool life by up to 50% compared to uncoated carbide.
- Exceptional wear resistance — Nano-crystalline structure reduces abrasive wear by up to 40% compared to conventional PVD coatings
- Superior heat resistance — Stable performance at cutting temperatures up to 900°C, enabling higher cutting speeds
- Low coefficient of friction — Minimizes built-up edge formation and ensures smooth chip flow
- High substrate toughness — Ultra-fine grain carbide base prevents chipping and micro-fractures under intermittent loads
- Optimized for steel machining — ISO P10-P30 application range with first-choice performance on carbon and alloy steels

Chipbreaker Profile
S120N geometry features a heavy-duty point design with reinforced web and thick core for maximum stability in large-diameter drilling. The wide flute geometry accommodates high-volume chip evacuation while the dual-margin design ensures superior hole straightness in deep-hole applications.
Key chipbreaker characteristics:
- Positive rake angle ground geometry for reduced cutting forces
- Polished flute surface treatment to prevent chip adhesion
- Variable helix design for stable chip curling across feed ranges
- Reinforced corner geometry for enhanced edge stability
Recommended Applications & Workpiece Materials
- Carbon Steels (S10C–S55C, S45C, S50C) — Excellent chip control and tool life
- Alloy Steels (SCM440, SNCM439, SCr420) — High wear resistance under demanding cuts
- Stainless Steels (SUS304, SUS316, SUS430) — Reduced work hardening and built-up edge
- Cast Irons (FC250, FCD400, FCD700) — Superior abrasion resistance
- Tool Steels (SKD11, SKH51, SKS3) — Reliable performance in hardened pre-drilling
- General Structural Steels (SS400, SM490A) — Cost-effective high-speed drilling
Specifically suited for heavy machinery, automotive powertrain, energy sector, mold & die, and large structural component manufacturing.
Application Map by Operation
| Operation | Suitability | Recommended Conditions |
|---|---|---|
| Through Hole Drilling | ★★★★★ Excellent | Vc=70-110 m/min, f=0.15-0.25 mm/rev |
| Blind Hole Drilling | ★★★★☆ Very Good | Vc=55-85 m/min, f=0.12-0.20 mm/rev |
| Peck Drilling (Deep Hole) | ★★★★★ Excellent | Vc=40-70 m/min, f=0.10-0.18 mm/rev, peck 0.5xD |
| High-Speed Machining | ★★★★☆ Very Good | Vc max 150 m/min, rigid setup required |
| Interrupted Cutting | ★★★☆☆ Good | Reduce Vc by 20%, increase feed slightly |
Recommended Cutting Conditions
The following parameters are recommended starting points. Optimize based on machine rigidity, coolant delivery, and workpiece material condition.
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (f) | Depth of Cut (ap) |
|---|---|---|---|
| Carbon Steel (S45C, S50C) | 70-110 m/min | 0.15-0.25 mm/rev | 3.0xD |
| Alloy Steel (SCM440, SNCM439) | 55-85 m/min | 0.12-0.20 mm/rev | 2.5xD |
| Stainless Steel (SUS304, SUS316) | 40-70 m/min | 0.10-0.18 mm/rev | 2.0xD |
| Cast Iron (FC250, FCD400) | 60-90 m/min | 0.12-0.22 mm/rev | 3.0xD |
| Tool Steel (SKD11, SKH51) | 55-85 m/min | 0.12-0.20 mm/rev | 2.0xD |
Operating Guidelines
- Coolant Delivery: Use high-pressure internal coolant (10–20 bar) for optimal chip evacuation and temperature control
- Peck Drilling: For holes deeper than 3.0xD, implement a peck cycle with 1xD peck depth and 0.3xD retract
- Toolholder Selection: Hydraulic or shrink-fit chucks with <0.008 mm runout accuracy. Side-lock end-mill holders suitable for standard milling centers.
- Entry Angle: Ensure perpendicular entry or use a spot drill to prevent walk-off on inclined surfaces
- Speed Ramp: Reduce cutting speed by 15–20% for the first 10 mm to stabilize entry conditions
- Chip Inspection: Monitor chip color and shape; silver-blue chips indicate optimal temperature range
- Tool Life Management: Replace drill when flank wear reaches 0.3 mm or when surface finish degrades
Toolholder Compatibility
The KDZ1110X3.0S120N features a 12.0 mm cylindrical shank compatible with standard collet and precision chuck systems:
- Collet Chucks: ER25 / ER32 collet systems with <0.015 mm runout accuracy
- Hydraulic Chucks: Recommended for high-precision applications requiring minimal vibration
- Shrink-Fit Chucks: Optimal for high-speed machining (>12,000 RPM) with maximum rigidity
- End-Mill Holders: Suitable for standard CNC milling centers with side-lock mechanisms
- Toolholder Material: Alloy steel or carbide-reinforced holders for dampening
