Grade Details – Key Grade Characteristics
TC Grade is a high-performance TiAlN-based PVD coating specifically developed for solid carbide drilling applications. It offers:
- Exceptional hardness: Coating hardness of ~3,300 HV minimizes abrasive wear.
- Thermal stability: Effective up to 900°C, reducing heat-induced plastic deformation.
- Low friction coefficient: Minimizes built-up edge (BUE) and improves chip evacuation.
- Oxidation resistance: Protects substrate during dry and high-speed machining.
- Enhanced adhesion: Multilayer architecture ensures coating integrity under cyclic loads.

Chipbreaker Profile
The 11/32 drill features an optimized 2-flute geometry with a polished flute surface and precision-ground margin lands. The chipbreaker design promotes:
- Controlled chip curling and segmentation for reliable evacuation.
- Reduced cutting forces, minimizing deflection in deep-hole applications.
- Stable chip flow in both through-hole and blind-hole operations.
- Minimized burr formation at exit, reducing secondary finishing requirements.
Recommended Applications & Workpiece Materials
| Material Group | Machinability | Recommended Condition |
|---|---|---|
| Carbon Steel (AISI 1045, 4140) | Excellent | Wet or MQL |
| Stainless Steel (304, 316) | Very Good | Wet recommended |
| Tool Steel (H13, D2) | Good | Wet or MQL |
| Cast Iron (GG25, GGG50) | Excellent | Dry or MQL |
| Titanium Alloys (Ti-6Al-4V) | Good | Wet mandatory |
Application Map by Operation
| Operation Type | Suitability | Max Depth Ratio |
|---|---|---|
| Through-hole Drilling | Optimal | 5×D |
| Blind-hole Drilling | Optimal | 3×D |
| Peck Drilling | Recommended | 8×D |
| Stack Drilling | Good | 2×D per plate |
| Enlarging / Reaming | Not Recommended | — |
Recommended Cutting Conditions
| Workpiece Material | Cutting Speed (Vc) | Feed per Rev (fn) |
|---|---|---|
| Low-Alloy Steel (< 900 MPa) | 60–90 m/min | 0.10–0.18 mm/rev |
| High-Alloy Steel (> 900 MPa) | 40–70 m/min | 0.08–0.15 mm/rev |
| Stainless Steel (AISI 304/316) | 30–55 m/min | 0.08–0.14 mm/rev |
| Gray Cast Iron (GG25) | 80–120 m/min | 0.12–0.22 mm/rev |
| Titanium Alloy (Ti-6Al-4V) | 20–35 m/min | 0.06–0.12 mm/rev |
Note: Values are starting recommendations. Optimize based on machine rigidity, coolant delivery, and workpiece fixturing.
Operating Guidelines
- Run-out tolerance: Ensure spindle TIR ≤ 0.01 mm for optimal tool life and hole accuracy.
- Coolant: High-pressure coolant (10–70 bar) is strongly recommended for steels and stainless steels. Minimum 5% emulsion concentration.
- Peck cycle: For depths > 3×D, use a peck depth of 1–1.5×D with full retract to break chips.
- Entry angle: Use a chamfer or center drill to avoid chipping on entry. Do not plunge into inclined surfaces > 5°.
- Speed ramp: Reduce spindle speed by 20% for the first 5 mm of engagement to stabilize entry.
- Re-sharpening: Not recommended; solid carbide drills are designed as disposable precision tools.
Toolholder Compatibility
| Holder Type | Compatibility | Notes |
|---|---|---|
| Hydraulic Chuck (HSK-A63) | Excellent | Best damping; recommended for >5×D |
| Shrink Fit Chuck | Excellent | Maximum torque transmission |
| ER Collet (ER16/ER20) | Good | Ensure collet ≤ 0.01 mm run-out |
| Drill Chuck (Keyless) | Acceptable | Limited to <3×D applications |
