Overview
The Fixed Shank Drill Bit by DUOMI CNC is engineered specifically for high-speed, heavy-duty industrial drilling operations. Built with rigid fixed-shank geometry, this tool minimizes runout, delivers superior hole accuracy, and significantly extends tool life under demanding continuous manufacturing conditions.
Whether integrated into automated transfer lines or standalone CNC machining centers, our fixed shank drill bits ensure dependable chip evacuation and pristine surface finishes across a wide spectrum of metallic substrates.
Key Features & Engineering Highlights
- Rigid Fixed Shank Construction: Eliminates slippage and vibration during high-feed rate drilling.
- Ultra-Precise Concentricity: Achieves strict TIR (Total Indicated Runout) tolerances within ±0.02mm for repeatable precision.
- Advanced Tool Geometry & Coating: Optimized flute design ensures rapid chip removal, preventing thermal buildup and premature edge wear.
- Multi-Material Versatility: Highly effective for non-ferrous alloys, tough structural steels, and precious metals alike.
Target Applications & Workpiece Materials
Designed for versatile B2B industrial applications including automotive components, aerospace fittings, electrical connectors, and precision mold manufacturing.
Compatible Materials
- Ferrous Metals: Structural Steel, Stainless Steel, Cast Iron
- Non-Ferrous Metals: Aluminum, Copper, Brass, Zinc
- Precious Metals: Platinum, Gold, Silver alloys
Technical & Economic Advantages
- Higher Throughput: Supports aggressive feed rates up to 30% higher than conventional bits without sacrificing hole quality.
- Extended Operational Life: Premium micro-grain carbide substrates increase tool longevity by up to 45%, reducing downtime and per-unit tooling costs.
- ISO & CE Standard Compliant: Manufactured under strict quality management processes adhering to ISO 9001 and international tooling standards.
