Kyocera 2ZDK033 C-Grade TEA05533 DRILL - Flat Bottom Drilling

Product Overview

The 2ZDK033 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.

Engineering Dimensions & Geometry

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 Cutting Conditions

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).
