Product Overview
The 2ZDK030 from Kyocera is a next-generation solid carbide flat-bottom drill engineered for precision counterboring, plunge milling, and high-accuracy drilling in flat and cylindrical surfaces. Featuring Grade C-Grade with Kyocera's proprietary MEGACOAT NANO technology, this tool delivers exceptional hardness (PVD multi-layer nano coating) and superior oxidation resistance up to 1,150°C. The unique S-curve chisel edge design minimizes entry impact forces, while the positive rake corner geometry dramatically reduces burr formation—making it the preferred choice for demanding aerospace and automotive applications.

Grade Details – Key Grade Characteristics
Grade C-Grade leverages Kyocera's MEGACOAT NANO PVD technology, featuring a specialized multi-layer nano-structure that delivers:
- Ultra-High Hardness: Nano-crystalline coating structure achieves >3,000 HV micro-hardness, preventing abrasive wear in high-silicon aluminum and hardened steels.
- Thermal Stability: Oxidation resistance up to 1,150°C enables dry machining and high-speed operations without thermal degradation.
- Low Friction Coefficient: The polished coating surface minimizes built-up edge and ensures smooth chip flow, critical for mirror-finish applications.
- Superior Chipping Resistance: The tough sub-micron carbide substrate absorbs impact forces during interrupted cuts and cross-hole drilling.

Chipbreaker Profile
The 2ZDK series features a unique flat-bottom geometry with an S-curve chisel edge that redefines drilling performance:
- S-Curve Chisel Edge: Distributes entry impact forces evenly, eliminating the "walking" effect common to conventional flat drills and ensuring precise hole positioning.
- Positive Rake Corner: The corner cutting edge features a positive rake angle that shears material cleanly, reducing burr height by up to 60% compared to standard flat-bottom drills.
- Wide Flute Design: Optimized flute width maintains excellent chip evacuation even at high feed rates (up to 0.3 mm/rev), preventing chip clogging in deep counterbores.
- Center Cutting Capability: The robust center edge allows plunge milling and helical interpolation without a pre-drilled pilot hole.
Recommended Applications & Workpiece Materials
| Material Group | Machinability | Recommended Vc (m/min) | Feed (mm/rev) |
|---|---|---|---|
| Carbon Steel (S45C, 1045) | ★★★★★ Excellent | 80–120 | 0.10–0.20 |
| Alloy Steel (SCM440, 4140) | ★★★★★ Excellent | 70–110 | 0.08–0.18 |
| Stainless Steel (SUS304, 316L) | ★★★★☆ Very Good | 50–80 | 0.08–0.15 |
| Cast Iron (FC250, FCD500) | ★★★★★ Excellent | 100–150 | 0.12–0.25 |
| Aluminum Alloy (A6061, A7075) | ★★★★★ Excellent | 150–250 | 0.15–0.30 |
| Titanium Alloy (Ti-6Al-4V) | ★★★☆☆ Good | 30–50 | 0.05–0.10 |
Application Map by Operation
| Operation Type | Suitability | Notes |
|---|---|---|
| Flat Surface Counterboring | ✓ Primary Application | Depth ≤ 1.5D; use rigid workholding |
| Cylinder Surface Drilling | ✓ Primary Application | S-curve edge compensates for curved entry; reduce feed 15% |
| Plunge Milling | ✓ Suitable | Not recommended for slotting; max depth 1.5D per plunge |
| Helical Interpolation | ✓ Suitable | Excellent for opening existing holes to larger diameters |
| Cross-Hole Drilling | △ Caution | Reduce speed 25%; use peck cycle to manage burr |
| Inclined Surface Drilling | ✓ Suitable | Spot drill first or use reduced feed until full engagement |
Recommended Cutting Conditions
| Material | Cutting Speed Vc (m/min) | Feed fn (mm/rev) | Coolant |
|---|---|---|---|
| Carbon Steel | 80–120 | 0.10–0.20 | Wet (Soluble Oil) |
| Alloy Steel | 70–110 | 0.08–0.18 | Wet (High Pressure) |
| Stainless Steel | 50–80 | 0.08–0.15 | Wet (High Pressure) |
| Cast Iron | 100–150 | 0.12–0.25 | Dry / Wet |
| Aluminum Alloy | 150–250 | 0.15–0.30 | Wet / MQL / Air Blast |
| Titanium Alloy | 30–50 | 0.05–0.10 | Wet (High Volume) |
Operating Guidelines
- Run-In Protocol: Perform 3–5 run-in holes at 70% of recommended Vc and feed to stabilize the cutting edge and allow the nano-coating to polish against the workpiece.
- Maximum Drilling Depth: Do not exceed 1.5 × DC in a single pass. For deeper features, use multiple plunge passes with 0.5 mm retract for chip clearing.
- Slotting Warning: This tool is specifically designed for plunge milling and counterboring. Slotting is NOT recommended as lateral forces will compromise tool life and accuracy.
- Coolant Concentration: When machining stainless steel or titanium, maintain water-soluble coolant concentration at 8–12% and ensure adequate flow to the cutting zone.
- Tool Life Check: Inspect the corner edge after every 100 holes. Replace when corner wear exceeds 0.05 mm or when burr height increases beyond specification.
- Storage: Keep in original packaging. Avoid contact with other tools. Store in a climate-controlled environment (15–25°C, <60% RH).
