Onsrud 61-041 Single Edge Router Bit 1/8 in Solid Carbide

Product Description

The ONSRUD 61-041 is a single-edge, straight-flute router bit designed for precision cutting in hard plastics and similar engineered materials. Built from solid carbide, it features a 1/8-inch cutter diameter and a 5/16-inch length of cut, making it well-suited for profiling, slotting, and trimming operations that demand clean, accurate edges. The right-hand cutting geometry and square end produce flat-bottomed cuts with minimal material distortion. This bit is intended for use in CNC routing applications and handheld router setups where tight tolerances and surface finish quality are priorities for trade and production environments.

This router bit is designed for use on hard plastic materials in both production and fabrication settings. Typical applications include cutting, trimming, and profiling extruded acrylic sheets, polycarbonate panels, PVC trim stock, HDPE, UHMW, polyethylene, polypropylene, polystyrene, and similar hard plastic substrates. Its compact 1/8-inch diameter makes it suitable for narrow slot cutting and detailed profile work. The 1/4-inch shank diameter fits standard router collets used in benchtop and CNC router systems.

Key Features

• Solid carbide construction for wear resistance in hard plastic applications
• Single-edge, straight-flute design for efficient chip evacuation
• Square end geometry for flat-bottomed cuts and clean edge profiles
• Right-hand cutting direction for standard router spindle operation
• 1/4-inch shank diameter fits common router collet sizes
• Non-piloted design for unrestricted freehand and CNC routing paths

Compatibility

Rated for use on extruded acrylic, HDPE, hard plastics, polyvinylchloride, polycarbonate, polyethylene, polypropylene, polystyrene, and UHMW. Part of the ONSRUD 61-000P series.

Installation Notes

Installation is performed by machinists, fabricators, or CNC operators familiar with router tooling. Power down and de-energize the router spindle completely before changing bits. Secure the shank fully within the collet to the recommended engagement depth per the router manufacturer's guidelines. Always verify spindle speed compatibility with the bit diameter and workpiece material before beginning a cut.
