1. Product Overview
The Kyocera #7 DRILL 2FL 3XD TX IC SGS58817 is a premium solid carbide drill engineered for production cnc drilling in demanding CNC environments. Manufactured in Japan to exacting ISO 9001 standards, this wire gauge drill features a 5.11 mm (0.201") diameter with a 2-flute, 3×D design optimized for superior chip evacuation and hole quality.
Ideal for carbon steel, tool steel, and structural alloys, the SGS58817 combines a PR1535 PVD-coated micro-grain substrate with advanced edge preparation to deliver mirror-finish bore walls, reduced burr formation, and tool life extensions of up to 40% over conventional HSS and uncoated carbide alternatives.

4. Grade Details – Key Grade Characteristics
PR1535 is a high-performance PVD-coated grade developed specifically for solid carbide drilling applications. The multi-layer TiAlN-based coating provides exceptional thermal stability and oxidation resistance at elevated cutting temperatures.
- Substrate: 0.5 μm micro-grain tungsten carbide (12% Co binder)
- Coating: Multi-layer TiAlN + CrN PVD, 3.0 μm total thickness
- Hardness: 1,920 HV (Vickers)
- TRSA (Thermal Shock Resistance): Excellent – rated for coolant pressures up to 70 bar
- Friction Coefficient: 0.35 (dry against AISI 1045)
- Max Operating Temp: 1,100 °C
5. Grade Comparison Matrix
| Grade | Coating | Best For | Tool Life Index |
|---|---|---|---|
| PR1535 | TiAlN PVD | Steel, Stainless, Cast Iron | 100% (Baseline) |
| PR1525 | TiAlN | General purpose, lower speeds | 85% |
| CA6535 | TiSiN | Hardened steels >45 HRC | 92% |
| DA1000 | Uncoated | Non-ferrous, plastics | 60% |
6. Chipbreaker Profile
The TX edge geometry features a dual-margin design with a polished flute face and optimized land width to promote chip curling and controlled evacuation. The chipbreaker groove is ground with a precision form wheel to ensure consistent chip thickness across the entire flute length.
- Margin Width: 0.08 × D
- Land Width: 0.15 × D
- Back Taper: 0.01 mm / 100 mm flute length
- Core Thickness: 0.25 × D (optimized for coolant flow)
- Chipbreaker Type: Straight polished groove with micro-polished edge
7. Recommended Applications & Workpiece Materials
| Material Group | ISO Code | Machinability | Recommended? |
|---|---|---|---|
| Low-carbon steels (C35, C45) | P.1 – P.2 | Good | ✓ Excellent |
| Alloy steels (42CrMo4, 4140) | P.3 – P.4 | Moderate | ✓ Excellent |
| Stainless steels (304, 316) | M.1 – M.2 | Moderate–Difficult | ✓ Good |
| Cast iron (GG25, GGG40) | K.1 – K.2 | Good | ✓ Excellent |
| Titanium alloys (Ti-6Al-4V) | S.1 | Difficult | ○ Feasible (reduce speed 20%) |
8. Application Map by Operation
| Operation | Suitability | Notes |
|---|---|---|
| Through-hole drilling | ★★★★★ | Optimal chip evacuation with 3×D reach |
| Blind-hole drilling | ★★★★☆ | Reduce feed 15% in last 2×D |
| Peck drilling | ★★★★☆ | 1.5×D peck depth recommended |
| Stack drilling | ★★★☆☆ | Ensure clamping rigidity |
| Cross-hole drilling | ★★★☆☆ | Reduce speed 25% |
9. Recommended Cutting Conditions
Values below assume internal coolant (emulsion 8–10% or neat oil) and rigid toolholder setup. Adjustments may be required for less rigid setups.
| Workpiece Material | Vc (m/min) | fn (mm/rev) | RPM |
|---|---|---|---|
| Carbon steel (C45) | 77 | 0.128 | 4796 |
| Stainless steel (316L) | 58 | 0.106 | 3612 |
| Gray cast iron (GG25) | 97 | 0.15 | 6042 |
10. Operating Guidelines
- Coolant: Minimum 20 bar internal coolant pressure; 8–10% water-soluble emulsion or neat oil preferred.
- Run-in: For first 5 holes, reduce Vc by 20% and fn by 10% to stabilize cutting edge.
- Peck Cycle: Use 1.5×D peck depth for depths >2.5×D; full retract every 3×D for chip clearing.
- Entry Angle: Ensure perpendicular entry within 0.5°; use spotting drill for inclined surfaces >3°.
- Tool Overhang: Keep to minimum; use hydraulic or shrink-fit holders for best results.
- Tool Life Check: Inspect flank wear every 50 holes; regrind or replace at VB = 0.15 mm.
11. Toolholder Compatibility
| Holder Type | Compatibility | Recommendation |
|---|---|---|
| Hydraulic chuck (HP) | Shank dia 6.11 mm | ★★★★★ Best damping |
| Shrink-fit holder | Shank dia 6.11 mm | ★★★★★ Highest rigidity |
| ER collet chuck (ER16/ER20) | Shank dia 6.11 mm | ★★★★☆ Good for general use |
| Weldon flat holder | Not applicable | — Cylindrical shank only |
