Introducing the BOSCH 85903MC 1/4 in. Solid Carbide Double-Flute Downcut Spiral Router Bit—built for speed, precision, and long life in wood, plastic, and laminate. It’s the kind of everyday工具 you reach for when you want clean edges and fewer post-cut touch-ups.

Key Features & Design

• Through cutting with downward pressure: Downcut design – ideal for template cutting when downward pressure and chip removal are advantageous.
• Micrograin solid carbide construction: Ensures consistently smooth finish cuts, with superior wear resistance and edge retention.
• Double-flute / Spiral design: Two cutting edges for efficient material removal and a crisp, tear-free surface.
• Industrial/CNC ready: Built for high-duty cycle applications with fast feed rates and long bit life.
• Rigid, long-lasting build: Solid carbide delivers the best rigidity and longevity for tough, hard-to-route materials.
• Upgrade-ready performance: Upgraded micrograin carbide engineered for precise cuts and extended bit life.
• Applications: Mortising, edge forming, trimming, surface forming, and cabinetry/joinery in wood, plastic, and laminate.
