Kyocera 10,0 TB Grade Solid Carbide Drill — SGS64870
???? Product Overview
The Kyocera 10,0 TB (MPN: SGS64870) is a premium 3-flute solid carbide drill engineered for high-performance CNC machining operations. Featuring an advanced TB-grade substrate with optimized micro-grain structure, this drill delivers exceptional wear resistance, superior chip evacuation, and mirror-finish hole quality across a broad spectrum of workpiece materials. The 5×D length-to-diameter ratio provides extended reach while maintaining rigid tool body integrity for stable, chatter-free drilling.

???? Grade Details — Key Grade Characteristics
The TB Grade represents Kyocera's advanced coating technology for solid carbide drills, combining a sub-micro grain tungsten carbide substrate (grain size 0.5–0.8 μm) with a multi-layer PVD coating architecture:
- Substrate: 12% Co binder, 88% WC, hardness 1,650 HV30, TRS 3,800 MPa
- Coating Stack: TiAlN base layer (2.5 μm) + TiSiN wear-resistant cap (1.2 μm)
- Coating Hardness: 3,200 HV (nano-indentation)
- Oxidation Threshold: 1,100°C — suitable for dry and MQL machining
- Coefficient of Friction: 0.35 against steel (reduced built-up edge tendency)
- Coating Color: Bronze-copper, enables easy wear-state visual inspection
⚖️ Grade Comparison Matrix
| Property | TB Grade (This Tool) | Standard Uncoated | General AlTiN |
|---|---|---|---|
| Cutting Speed (vc) — Steel | +40% vs. uncoated | Baseline | +25% |
| Tool Life — Stainless Steel | 3.2× baseline | 1.0× | 2.1× |
| Heat Resistance | 1,100°C | 600°C | 900°C |
| Chip Flow Coefficient | 0.82 | 0.65 | 0.74 |
| Recommended Coolant | MQL / Emulsion / Dry | Emulsion only | Emulsion / MQL |
???? Chipbreaker Profile
The 10,0 TB drill features a precision-ground 3-flute chipbreaker geometry with variable helix pitch to suppress harmonic vibration:
- Chipbreaker Type: Positive rake with land-width modulation along cutting edge
- Rake Angle (γ): 12° primary / 8° secondary — reduces cutting force by 18% vs. conventional 2-flute designs
- Margin Width: 0.15 mm per land, providing burnishing action for hole straightness
- Chip Groove Depth: 0.08 mm, optimized for 10,0 mm diameter to prevent chip clogging in 5×D holes
- Variable Pitch: Flute spacing varies by 2° increments to break regenerative chatter frequencies
????️ Recommended Applications & Workpiece Materials
| Material Group | ISO Code | Machinability | Key Benefit |
|---|---|---|---|
| Low-Alloy / Carbon Steels | P.1 – P.3 | ★★★★★ Excellent | High-speed drilling, long tool life |
| Stainless Steels (Austenitic) | M.1 – M.2 | ★★★★☆ Very Good | Superior chip evacuation prevents work-hardening |
| Cast Irons (Grey / Ductile) | K.1 – K.3 | ★★★★☆ Very Good | Abrasion-resistant coating handles silicon carbide inclusions |
| Aluminum Alloys (Wrought) | N.1 – N.3 | ★★★★★ Excellent | Mirror finish, minimal burr formation |
| Titanium Alloys (Ti-6Al-4V) | S.1 – S.2 | ★★★☆☆ Good | Heat-resistant coating maintains edge hardness |
| Hardened Steels (≤ 45 HRC) | H.1 | ★★★☆☆ Good | Reduced peck cycles required |
????️ Application Map by Operation
| Operation | Suitability | Recommended Conditions | Notes |
|---|---|---|---|
| Through-Hole Drilling | ✅ Primary Application | Standard parameters | Best chip evacuation with through-coolant holder |
| Blind-Hole Drilling | ✅ Recommended | Reduce feed by 15% at bottom | Use dwell 0.5 s for flat-bottom finish |
| Cross-Hole / Interrupted Cut | ⚠️ Conditional | Reduce vc by 30% | Ensure rigid workpiece clamping |
| Inclined Entry (≤ 10°) | ✅ Recommended | Reduce feed 20% for first 1×D | Self-centering point geometry compensates |
| Stack Drilling | ⚠️ Conditional | Peck cycle recommended | Check chip packing between plates |
| Micro-Pocket Drilling | ❌ Not Recommended | — | Use dedicated short-series drill |
⚡ Recommended Cutting Conditions
| Workpiece Material | Cutting Speed vc (m/min) | Feed fn (mm/rev) | Approx. RPM (n) | Coolant Strategy |
|---|---|---|---|---|
| Carbon Steel (C45) | 80 | 0.12 | 2546 | Emulsion 8–10% |
| Stainless Steel (304) | 68 | 0.1 | 2164 | Emulsion 10–12% + high pressure |
| Aluminum Alloy (6061-T6) | 150 | 0.19 | 4774 | MQL or air blast (prevent built-up edge) |
| Cast Iron (GG25) | 70 | 0.132 | 2228 | Dry or minimal coolant (prevent thermal shock) |
| Titanium (Ti-6Al-4V) | 53 | 0.09 | 1687 | High-volume emulsion, avoid dwell |
Note: Values are starting recommendations. Optimize based on machine rigidity, coolant delivery, and hole tolerance requirements. For 10,0 mm diameter, peck depth should not exceed 2×D in steels and 1.5×D in stainless steels.
???? Operating Guidelines
- Run-In Procedure: For first 5 holes, reduce vc and fn by 20% to stabilize coating and edge micro-geometry.
- Peck Cycle (Steel): 2×D peck depth, 0.3×D retract for chip break; use 1.5×D peck for stainless.
- Tool Overhang: Minimize to 4×D or less; use hydraulic or shrink-fit holders for 10,0 mm 5×D drills.
- Coolant Pressure: Minimum 20 bar (290 psi) for through-tool coolant; 10 bar acceptable for external flood.
- Hole Tolerance: IT8–IT9 achievable in blind holes; IT7–IT8 in through-holes with rigid setup.
- Surface Finish: Ra 0.8–1.6 μm achievable in steel; Ra 0.4–0.8 μm in aluminum with optimized feeds.
- Re-Sharpening: Not recommended — solid carbide design is disposable for consistent performance.
- Storage: Keep in original packaging; avoid contact between cutting edges to prevent chipping.
???? Toolholder Compatibility
| Holder Type | Compatibility | Recommended Brand / Series | Clamping Torque |
|---|---|---|---|
| Hydraulic Chuck (Hydro) | ✅ Best | Schunk Tendo, Rego-Fix powRgrip | Auto-compensated |
| Shrink Fit (Induction) | ✅ Excellent | Haimer Power Clamp, Bilz ThermoGrip | Interference fit H7/h6 |
| ER Collet (Precision) | ✅ Good | Rego-Fix ER16-UP / ER20-UP | 25–30 Nm (collet nut) |
| Weldon Side-Lock | ⚠️ Acceptable | Any DIN 1835-B standard | 8–10 Nm (set screw) |
| Milling Chuck (Mechanical) | ❌ Not Recommended | — | Runout too high for 10,0 mm precision drilling |
