Precision meets reliability with the BOSCH 85900MC solid carbide double-flute down-cut router bit. Designed for cabinetry, edge work, and joinery, it delivers clean edges and long tool life for wood, plastic, and laminate projects.

Key Features & Design

• Material & construction: Micrograin solid carbide with a Bosch-exclusive heat-treating process for hardness, edge retention, and an extra-fine finish.
• Cut Diameter: 0.125 in (1/8 in).
• Number of Flutes: 2 (double-flute) for efficient chip removal and smooth cuts.
• Spiral Design: Downcut spiral for downward chip flow and the best finish on the top surface of the workpiece.
• Shank Details: 1/4 in shank; shank length 1.5 in; overall length 2 in.
• Material Benefits: Solid carbide build provides rigidity and long life, enabling faster feed rates and better performance on hard-to-route materials.
• Finishing & Accuracy: Upgraded micrograin carbide and Bosch-exclusive heat-treating deliver precise cuts and long bit life, with consistent accuracy across hundreds of profiles.
• Applications: Mortising, edge forming, trimming, surface forming, and cabinetry/joinery in wood, plastic, and laminate.
• Operational Notes: Template cutting with downward pressure can yield clean, accurate cuts; augering action helps clear chips from the cut.
• Bearing: Bearing Included: Not Required.
