Onsrud 56-650 Square End Router Bit 1/2 in Solid Carbide

Product Description

The ONSRUD 56-650 is a 2-flute, square end, double edge router bit designed for cutting plastics and hard materials in routing applications. Built from solid carbide, it delivers consistent edge quality at a 0.5 inch cutter diameter with a 1 inch length of cut (LOC) and a 3 inch overall length (OAL). The straight flute geometry paired with a right-hand cutting direction suits high-speed routing where clean, burr-free edges are required. Installed by machining professionals and fabricators, this bit handles repeated production runs without the chipping common to lesser tooling grades.

The 56-650 is suited for routing ABS, Acetal, Acrylic, HDPE, HIPS, Polyethylene terephthalate (PET), Polyvinylchloride (PVC), Polycarbonate, Polyethylene, Polypropylene, Polystyrene, and UHMW. It fits standard 1/2 inch collet routers and CNC routing spindles used in plastics fabrication, sign making, and light industrial part production. The double edge design makes it a practical choice for profiling, slotting, and full-depth cuts through sheet and plate stock.

Key Features

• Solid carbide construction for extended tool life in abrasive plastic materials
• Square end geometry produces flat-bottomed cuts and sharp 90-degree corners
• Double edge, straight flute design for clean, consistent chip evacuation
• Right-hand cutting direction compatible with standard CNC and handheld router setups
• Non-piloted design provides full routing flexibility without bearing limitations
• Part of the ONSRUD 56-600 Series for organized tooling inventory management

Compatibility

Compatible with routing applications involving ABS, Acetal, Acrylic, HDPE, HIPS, Polyethylene terephthalate, Polyvinylchloride, Polycarbonate, Polyethylene, Polypropylene, Polystyrene, and UHMW. Requires a 1/2 inch collet on the host router or spindle.

Installation Notes

Installation and tool changes should be performed by qualified machine operators with the router powered off and fully de-energized. Verify collet condition and torque the collet nut to the router or spindle manufacturer specification before operation. Inspect the bit for chips or cracks before each use and do not exceed the spindle speed rating of the host machine. Follow applicable shop safety standards and machine guarding requirements when routing plastics.
