Onsrud 61-044 Single Edge Router Bit 1/8 in Solid Carbide

Product Description

The ONSRUD 61-044 is a single-edge, straight-flute router bit designed for precision cutting in hard plastics and engineered thermoplastics. Ground from solid carbide, it delivers clean, accurate cuts with minimal chipping or melting at the cut edge. The bit features a 1/8-inch cutter diameter, a 1/2-inch length of cut, and a 2-inch overall length. The right-hand cutting geometry and single-flute design promote efficient chip evacuation, which is critical when routing plastics where heat buildup can cause material deformation. Licensed CNC machinists and plastics fabricators are the primary installers of this tooling.

This router bit is engineered for use in CNC routing and handheld router applications involving hard plastic sheet goods and profiles. Confirmed material applications include extruded acrylic, HDPE, polycarbonate, polyethylene, polypropylene, polystyrene, polyvinylchloride, UHMW, and other hard plastics. The 1/8-inch shank diameter makes it compatible with standard 1/8-inch collets on CNC routers and trim routers. It is part of the ONSRUD 61-000P series, which targets hard material plastic cutting applications.

Key Features

• Solid carbide construction for extended tool life in abrasive plastic materials
• Single-flute, straight design promotes chip clearance and reduces heat at the cut
• Square end geometry produces flat-bottomed cuts and clean profile edges
• Right-hand cut orientation compatible with standard CNC and handheld router spindle direction
• 1/8-inch shank fits standard collets without adapters
• Non-piloted design for full-depth plunge and profile routing flexibility

Compatibility

Confirmed material applications include extruded acrylic, HDPE, polycarbonate, polyethylene, polypropylene, polystyrene, polyvinylchloride, UHMW, and other hard plastics. Designed for use in any CNC or handheld router equipped with a 1/8-inch collet.

Installation Notes

Installation and use should be performed by qualified machinists or CNC operators familiar with rotating tooling safety. Ensure the router spindle is fully powered down and the collet is released before changing bits. Confirm collet size matches the 1/8-inch shank before tightening. Follow machine manufacturer feed rate and spindle speed recommendations for the specific plastic material being routed.
