Product Overview
The Kyocera 21/64 TN SGS51300 is a premium solid carbide drill engineered for high-performance CNC machining. Designed with a 2-flute, 3×D geometry and advanced TN carbide substrate, this tool delivers exceptional chip evacuation, superior surface finish, and extended tool life across a broad spectrum of workpiece materials. Ideal for precision hole-making in aerospace, automotive, and general engineering applications.
ISO Designation Breakdown
| Designation Element | Value | Description |
| Manufacturer | Kyocera | OEM genuine product |
| Model Code | 21/64 | Tool size / series identifier |
| Grade | TN | Carbide grade with PVD coating |
| MPN | SGS51300 | Manufacturer part number |
| Flute Count | 2FL | Two-flute design |
| L/D Ratio | 3×D | Three times diameter flute length |
Engineering Dimensions & Geometry
| Parameter | Value | Tolerance |
| Drill Diameter (D) | 8.33 mm | h5 |
| Overall Length (L) | 66.6 mm | ±0.5 mm |
| Flute Length (l) | 25.0 mm | ±0.3 mm |
| Shank Diameter (d) | 8.33 mm | h6 |
| Helix Angle | 130° | ±2° |
| Point Angle | 135° | ±1° |

Grade Details – Key Grade Characteristics
The TN grade features a micro-grain carbide substrate with a multi-layer PVD coating optimized for high-speed drilling. Key characteristics include:
- High hardness (HV 30 > 1,600) for wear resistance
- Excellent thermal stability up to 900°C
- Low coefficient of friction for reduced built-up edge
- Optimized cobalt content for toughness and edge integrity
Grade Comparison Matrix
| Grade | Coating | Best For | Speed Range |
| TN | TiAlN PVD | Steel, Stainless, Cast Iron | High |
| CA6535 | TiAlN | General Purpose | Medium–High |
| PR1535 | TiSiN | Hardened Steel > 50 HRC | Medium |
Chipbreaker Profile
The 21/64 incorporates a precision-ground chipbreaker geometry designed to curl and evacuate chips efficiently. The 2-flute design with polished flutes minimizes chip packing, even in deep-hole applications up to 3×D. The optimized flute profile ensures stable chip flow, reducing heat generation and improving hole quality.

Application Map by Operation
| Operation | Suitability | Notes |
| Through-Hole Drilling | ★★★★★ | Optimal chip evacuation |
| Blind-Hole Drilling | ★★★★☆ | Use reduced feed near bottom |
| Peck Drilling | ★★★★★ | Recommended for >2.5×D |
| Counterboring | ★★★☆☆ | Limited by point geometry |
Recommended Cutting Conditions
| Material | Vc (m/min) | fn (mm/rev) | Coolant |
| Low-Carbon Steel | 80–120 | 0.15–0.30 | Internal / External |
| Alloy Steel (35 HRC) | 60–90 | 0.12–0.25 | Internal / External |

| Aluminum Alloy | 150–250 | 0.20–0.40 | Internal / External |
Operating Guidelines
- Always use a rigid toolholder and minimize overhang to prevent vibration
- Ensure coolant pressure ≥ 20 bar for effective chip evacuation in deep holes
- Reduce feed rate by 30% when entering cross-holes or interrupted cuts
- Inspect tool point after every 50 holes in abrasive materials
- Use peck cycles (Q) of 1–1.5×D for holes deeper than 2.5×D
- Maintain spindle run-out within 0.01 mm TIR for best results
Toolholder Compatibility
| Holder Type | Compatibility | Notes |
| Hydraulic Chuck | ★★★★★ | Best damping, recommended |
| Shrink Fit | ★★★★★ | High rigidity, excellent torque |
| ER Collet (ER25/ER32) | ★★★★☆ | Use precision collets (≤5 µm) |
| Weldon Flat | ★★★☆☆ | Not recommended for this series |
