Onsrud 61-162 Single Edge Router Bit 0.5in Solid Carbide

Product Description

The ONSRUD 61-162 is a single-edge, straight-flute router bit designed for cutting hard plastics and engineered thermoplastics in CNC and manual routing applications. Built from solid carbide, it features a 0.5-inch cutter diameter, a 1-inch length of cut, and a 3-inch overall length. The square end geometry produces clean, flat-bottomed cuts, while the single-flute design clears chips aggressively to reduce heat buildup in thermoplastic materials. This bit is installed and operated by machinists, CNC programmers, and fabricators working in plastics fabrication and sign-making shops.

The 61-162 is suited for routing extruded acrylic, HDPE, hard plastics, polyvinyl chloride, polycarbonate, polyethylene, polypropylene, polystyrene, and UHMW. It performs in both production CNC routing environments and benchtop router table setups where a 0.5-inch shank collet is available. The right-hand cutting direction is standard for conventional CNC spindle rotation. This bit belongs to the ONSRUD 61-000P series, which targets hard and semi-rigid plastic stock.

Key Features

• Solid carbide construction for wear resistance in abrasive thermoplastic materials
• Single-flute straight design maximizes chip evacuation and reduces heat in plastic cutting
• Square end geometry delivers flat-bottomed slots and profiles
• 0.5-inch shank diameter fits standard half-inch router collets and CNC tool holders
• Right-hand cut compatible with standard CNC spindle rotation
• Non-piloted design for full-depth freehand and fixtured routing passes

Compatibility

Designed for use on extruded acrylic, HDPE, hard plastics, polyvinyl chloride, polycarbonate, polyethylene, polypropylene, polystyrene, and UHMW. Fits any router or CNC spindle accepting a 0.5-inch shank collet.

Installation Notes

Installation is performed by machinists or CNC operators. Secure the shank fully into a clean, properly sized collet before tightening to the tool manufacturer's specified procedure. Power down and lock out the spindle before changing tooling. Verify spindle speed and feed rate against the material manufacturer's recommendations before beginning a cut, as improper parameters are the leading cause of melting or chipping in thermoplastics.
