4. Grade Details – Key Grade Characteristics
Grade TC represents Kyocera's advanced carbide substrate technology specifically developed for micro-to-medium diameter drilling applications:
- Nano-layered PVD coating minimizes friction and extends tool life in high-speed applications.
- High hardness (HV 1,650 ± 100) combined with transverse rupture strength > 3,800 MPa.
- Superior edge retention reduces the frequency of tool changes and improves process stability.
- Compatible with minimum quantity lubrication (MQL) and wet machining environments.
5. Grade Comparison Matrix
| Property | Grade TC | Standard Grade | Competitor Equivalent |
|---|---|---|---|
| Hardness (HV) | 1,650 | 1,500 | 1,550 |
| TRS (MPa) | 3,800+ | 3,200 | 3,400 |

| Recommended Max Speed | 120 m/min | 80 m/min | 90 m/min |
6. Chipbreaker Profile
The 3,3 mm DRILL 2FL features an optimized flute geometry designed for efficient chip evacuation in deep-hole and through-hole applications:
- Flute Form: Parabolic helix with polished rake face (Ra 0.2 μm) to minimize built-up edge.
- Chipbreaker Design: Continuous margin with secondary land clearance for stable chip curling and breakage.
- Evacuation Channel: Open flute profile with 38% core diameter ratio ensures unobstructed chip flow up to 3×D drilling depth.
- Edge Preparation: Micro-honed cutting edge (0.02–0.03 mm) enhances edge integrity and prevents chipping on entry.
7. Recommended Applications & Workpiece Materials
Delivers exceptional results in hardened steels up to 50 HRC for mold and die applications.
| Material Group | Hardness Range | Performance Rating |
|---|---|---|
| Carbon Steel (P) | < 30 HRC | ★★★★★ Excellent |
| Alloy Steel (P) | 30–45 HRC | ★★★★☆ Very Good |
| Stainless Steel (M) | < 35 HRC | ★★★★☆ Very Good |
| Cast Iron (K) | 150–250 HB | ★★★★★ Excellent |
| Aluminum (N) | < 100 HB | ★★★★★ Excellent |
| Hardened Steel (H) | 45–55 HRC | ★★★☆☆ Good |
8. Application Map by Operation
| Operation Type | Suitability | Max Depth | Remarks |
|---|---|---|---|
| Through-Hole Drilling | Recommended | 3×D | Use peck cycle for >2.5×D |
| Blind-Hole Drilling | Recommended | 2.5×D | Ensure adequate bottom clearance |
| Spot Drilling | Suitable | 0.5×D | Use reduced feed rate |
| Chamfering | Not Recommended | — | Use dedicated chamfer tool |
| Enlarging | Suitable with care | 1.5×D | Reduce speed by 20% |
9. Recommended Cutting Conditions
| Material | Cutting Speed Vc (m/min) | Feed fn (mm/rev) | Coolant |
|---|---|---|---|
| Carbon Steel | 47–67 | 0.116–0.146 | Emulsion / MQL |
| Alloy Steel | 37–57 | 0.116–0.136 | Emulsion |
| Stainless Steel | 32–42 | 0.116–0.126 | Emulsion (high pressure) |
| Cast Iron | 57–77 | 0.126–0.156 | Dry / Compressed air |
| Aluminum | 77–107 | 0.136–0.166 | MQL / Dry |
Start at the lower bound and increase gradually based on machine rigidity and workpiece clamping. Values assume stable CNC machining center with ISO 40 taper or higher.
10. Operating Guidelines
- Run-out Tolerance: Ensure spindle run-out does not exceed 0.01 mm at the tool tip to prevent uneven wear and breakage.
- Peck Drilling: For holes deeper than 2.5×D, employ a peck cycle with 0.5×D retract to clear chips and prevent packing.
- Coolant Delivery: Direct coolant to the cutting zone at minimum 3-bar pressure. For MQL, use vegetable-based lubricant at 10–30 ml/h.
- Entry Angle: When drilling inclined surfaces, reduce feed by 30% for the first 0.5×D to avoid walk-off.
- Tool Life Monitoring: Replace tool when flank wear (VB) reaches 0.15 mm or when burr formation exceeds 0.05 mm.
- Storage: Store in original packaging at 15–25°C with <60% relative humidity to prevent corrosion of the polished flutes.
11. Toolholder Compatibility
| Holder Type | Compatible | Notes |
|---|---|---|
| Hydraulic Chuck (Hydro) | Yes – Preferred | Best run-out <0.005 mm; ideal for 3,3 mm |
| Shrink Fit | Yes | Excellent gripping force; ensure thermal profile matches carbide |
| ER Collet (ER16/ER20) | Yes | Use precision collet (AA grade) for diameters <3 mm |
| Drill Chuck (Keyless) | Not Recommended | Excessive run-out leads to premature failure |
| Weldon Side-Lock | No | Not suitable for solid carbide micro-drills |
