Onsrud 56-162 Square End Double Edge Router Bit

Product Description

The ONSRUD 56-162 is a two-flute, square end, double edge solid carbide router bit designed for precision routing in hard and engineered materials. With a 0.5-inch cutter diameter and a 1-inch length of cut, it delivers clean, full-depth passes in a single setup. The straight flute geometry and right-hand cutting direction produce consistent chip evacuation and smooth edge finishes. Solid carbide construction provides the hardness and wear resistance required for demanding production environments. Licensed HVAC techs, machinists, and fabricators working with plastics and composite panels rely on this bit for repeatable performance across multiple material types.

This router bit is suited for CNC routing and handheld router applications where a 0.5-inch shank is required. It is engineered for use on a broad range of hard materials including ABS, acetal, acrylic, fiberglass, foam, nylon, polyvinylchloride, phenolic, and solid surfaces. The 3-inch overall length provides adequate clearance for most production fixtures and routing tables. It is a non-piloted bit, meaning it relies on a fence, template, or CNC program path for guidance rather than a bearing.

Key Features

• Solid carbide construction for hardness and long tool life in abrasive materials
• Square end geometry produces flat-bottomed cuts and sharp 90-degree edges
• Double edge, straight flute design for clean chip removal and smooth finishes
• Right-hand cutting direction compatible with standard CNC spindle rotation
• Non-piloted design for use with fences, templates, or programmed tool paths
• Series 56-000P engineered specifically for hard and engineered plastic materials

Compatibility

Designed for use on ABS, acetal, acrylic, fiberglass, foam, nylon, polyvinylchloride, phenolic, and solid surfaces. Fits any router collet or CNC spindle accepting a 0.5-inch shank. Non-piloted; requires external guidance for accurate cuts.

Installation Notes

Installation and tool changes should be performed with the router or CNC spindle fully powered down and locked out. Ensure the collet and shank surfaces are clean and free of debris before seating the bit. Follow the router or spindle manufacturer specifications for collet torque and minimum shank insertion depth. Eye protection and appropriate dust collection are required when routing fiberglass, phenolic, and other particle-generating materials.
