1. Product Overview
The Kyocera 10,5 DRILL 3FL 5XD TM IC SGS65235 is a premium solid carbide drill engineered for high-performance CNC machining operations. Featuring a 10.5mm diameter with a 3-flute design and 5×D length-to-diameter ratio, this drill is optimized for superior chip evacuation, dimensional accuracy, and extended tool life in demanding production environments. The TM grade PVD coating minimizes friction and heat generation, enabling stable high-speed drilling across a broad spectrum of workpiece materials.
Designed for through-hole and blind-hole applications, this drill incorporates internal coolant channels to ensure efficient temperature management at the cutting edge, reducing thermal cracking and improving surface finish quality. Ideal for aerospace, automotive, mold & die, and general precision engineering sectors.

6. Chipbreaker Profile
The 3-flute geometry of the 10,5 drill incorporates an advanced flute profile optimized for chip formation and evacuation in medium-to-long reach applications. The chipbreaker design features:
- Variable Helix Flutes: Reduces harmonic vibration and chatter during entry and exit, improving hole quality and tool life.
- Polished Flute Surface: Mirror-finish grinding (Ra ≤ 0.2 μm) minimizes chip adhesion and built-up edge formation, particularly effective in sticky materials such as stainless steel and titanium alloys.
- Progressive Core Taper: Core thickness increases from point to shank, providing maximum rigidity at the cutting zone while maintaining adequate chip pocket volume for evacuation.
- Split-Point Geometry: Self-centering 140° point with modified web thinning reduces thrust force by up to 30% compared to standard chisel-edge designs, enabling precise hole placement and reduced walk-off on angled surfaces.
- Internal Coolant Channels: Two independent coolant passages direct high-pressure coolant directly to the cutting lips, flushing chips upward through the flutes and maintaining thermal stability.
7. Recommended Applications & Workpiece Materials
| Material Group | Material Examples | Machinability | Recommended |
|---|---|---|---|
| P – Steel | Tool Steel, Structural Steel | Good – Excellent | ✓ Primary application |
| M – Stainless Steel | AISI 304, 316, 17-4PH, duplex | Moderate – Good | ✓ Recommended with coolant |
| K – Cast Iron | Gray cast iron, nodular iron, malleable iron | Excellent | ✓ Highly suitable |
| N – Non-Ferrous | Aluminum alloys, brass, copper | Excellent | ✓ Suitable (reduce speed) |
| S – Superalloys | Inconel 718, Hastelloy, Ti-6Al-4V | Difficult | △ Possible with reduced parameters |
8. Application Map by Operation
| Operation Type | Suitability | Notes |
|---|---|---|
| Through-Hole Drilling | ★★★★★ | Optimal chip evacuation; use standard peck cycle for depths >3×D |
| Blind-Hole Drilling | ★★★★☆ | Ensure adequate dwell at bottom; retract at 50% feed for chip break |
| Cross-Hole Drilling | ★★★☆☆ | Reduce feed by 30% when intersecting existing holes |
| Stack Drilling | ★★★★☆ | Clamp plates firmly; use high coolant pressure to prevent chip packing |
| Engraving / Spotting | ★★☆☆☆ | Not recommended; use dedicated spot drill for pilot holes |
| Peck Drilling (Deep Hole) | ★★★★★ | Standard peck depth 1.5–2.0×D; full retract every 3–4 pecks recommended |
9. Recommended Cutting Conditions
| Workpiece Material | Cutting Speed Vc (m/min) | Feed fn (mm/rev) | RPM (approx.) |
|---|---|---|---|
| Mild Steel (≤ 250 HB) | 100 | 0.255 | 3031 |
| Carbon / Alloy Steel (≤ 320 HB) | 60 | 0.207 | 1818 |
| Stainless Steel (AISI 304/316) | 40 | 0.17 | 1212 |
| Cast Iron (GG/GGG) | 100 | 0.285 | 3031 |
Note: Values are starting recommendations. Optimize based on machine rigidity, coolant delivery, and hole depth. For hardened steels (35–45 HRC), reduce Vc by 20–30% and fn by 10–15%.
10. Operating Guidelines
- Coolant: Use water-soluble coolant (8–10% concentration) or oil-based coolant at minimum pressure of 20 bar (290 psi) for optimal chip evacuation and thermal management. Internal coolant is mandatory for holes deeper than 3×D.
- Ramp Entry: For inclined or curved surfaces, program a helical ramp entry or use a spot drill to create a 90° starting surface. Avoid direct entry on surfaces >5° inclination without pilot hole.
- Peck Cycle: For 5×D drilling, use a peck depth of 1.0–1.5×D with full retract to break chips. For stack drilling or cross-hole applications, reduce peck depth to 0.5×D.
- Spindle Speed: Start at the lower end of the recommended Vc range and increase gradually while monitoring tool wear, hole diameter, and surface finish. Excessive speed causes premature corner wear.
- Feed Rate: Maintain consistent feed. Do not dwell at the bottom of the hole. Rapid retract at 150–200% of drilling feed to avoid chip re-cutting.
- Tool Overhang: Minimize tool overhang. Use hydraulic or shrink-fit holders for best results. Collet holders are acceptable for holes <3×D with stable workholding.
- Runout: Ensure total indicator runout (TIR) at the tool tip is ≤ 0.01 mm. Higher runout accelerates uneven flank wear and chipping.
- Tool Life Monitoring: Inspect cutting edges after every 50 holes or 30 minutes of cutting time. Replace when flank wear land (VBB) reaches 0.15 mm or when hole diameter exceeds upper tolerance limit.
