Product Overview
The Kyocera 10.1mm Solid Carbide Drill (SGS66574) is a high-performance 2FL-flute drill featuring a 5XD length-to-diameter ratio and TX-grade substrate with advanced PVD coating. Engineered for CNC machining centres and turning centres, this tool delivers exceptional hole quality, dimensional accuracy, and extended tool life in demanding production environments.
With internal coolant delivery (IC) and an optimised point geometry, the SGS66574 ensures efficient chip evacuation and reduced cutting temperatures, making it ideal for aerospace structural components, automotive transmission parts, mould & die manufacturing.

Recommended Applications & Workpiece Materials
The 10.1mm TX-grade drill is optimised for the following material groups and industrial sectors:
- Primary Materials: Alloy steels (42CrMo4), tool steels (H13, D2), stainless steels (316L), titanium alloys (Ti-6Al-4V)
- Ideal Industries: Aerospace, automotive, medical device manufacturing, general engineering, mould & die
- Hole Quality: IT8–IT9 tolerance, Ra 0.8–1.6 μm surface finish (depending on machine rigidity)
- Hole Depth Capability: Up to 5×D without pecking (with adequate coolant pressure > 3 MPa)
Application Map by Operation
| Operation | Suitability | Notes |
|---|---|---|
| Through-hole drilling | ★★★★★ Excellent | Optimal chip evacuation with through coolant |
| Blind-hole drilling | ★★★★☆ Very Good | Reduce feed by 20% in last 1×D |
| Stack drilling | ★★★★☆ Very Good | Ensure rigid clamping; use pilot hole if > 3×D |
| Cross-hole drilling | ★★★☆☆ Good | Reduce speed by 15%; use high coolant pressure |
| Inclined entry (> 5°) | ★★★☆☆ Good | Use spot drill or chamfer first to prevent walk |
| Interrupted cuts | ★★☆☆☆ Fair | Reduce feed by 30%; consider peck cycle |
Recommended Cutting Conditions
Parameters below are starting recommendations for stable CNC setups with adequate coolant delivery (minimum 3 MPa, 15 L/min). Adjust based on machine rigidity and workpiece clamping.
| Material Group | Cutting Speed vc (m/min) | Feed fn (mm/rev) |
|---|---|---|
| Carbon Steel (C35, C45) | 43–58 | 0.231–0.261 |
| Alloy Steel (42CrMo4, 16MnCr5) | 38–53 | 0.231–0.251 |
| Stainless Steel (304, 316L) | 27–37 | 0.221–0.231 |
| Cast Iron (GG25, GGG40) | 53–68 | 0.241–0.271 |
| Aluminium Alloy (6082, 7075) | 84–104 | 0.251–0.281 |
| Hardened Steel (45–50 HRC) | 20–35 | 0.05–0.08 |
Operating Guidelines
- Coolant: Use water-miscible cutting fluid (8–10% concentration) or neat oil. Minimum coolant pressure: 3 MPa (30 bar) for optimal chip evacuation.
- Pecking: For 5×D drilling, a single peck at 2.5×D is recommended when coolant pressure is below 3 MPa or in blind-hole applications.
- Spot Drilling: For inclined or curved surfaces, use a 90° or 120° spot drill to create a chamfer > 0.2 mm deep to prevent drill walk.
- Speed/Feed Entry: Reduce feed by 50% for the first 1 mm of engagement, then ramp to full feed over 0.5 mm.
- Exit Strategy: Reduce feed by 30% when drill tip breaks through to avoid burr formation and exit chipping.
- Tool Life Check: Inspect flank wear every 50 holes. Maximum allowable flank wear (VBmax) = 0.15 mm for steel applications.
