Onsrud 56-654 Square End Router Bit 1/2 in Solid Carbide

Product Description

The ONSRUD 56-654 is a two-flute, square end, double edge solid carbide router bit designed for high-speed routing of plastics and hard materials. With a 0.5 inch cutter diameter and a 1.75 inch length of cut, this straight-flute bit delivers clean, consistent edge profiles in CNC and handheld router applications. The solid carbide construction provides the hardness and heat resistance required for extended production runs on demanding thermoplastic materials. Right-hand cutting geometry suits standard spindle direction setups. At 0.33 pounds, the bit is well-suited for tooling inventories across fabrication shops and production environments.

The 56-654 is built for routing a wide range of thermoplastics and engineering-grade plastics in production and fabrication settings. Typical applications include sheet plastic fabrication, sign making, and panel cutting in light manufacturing. It fits routers accepting a 0.5 inch shank and is part of the ONSRUD 56-600 series, engineered specifically for performance on plastic substrates. Shops processing ABS, acrylic, HDPE, polycarbonate, PVC, polypropylene, UHMW, and related materials will find this bit a direct fit for their material stack.

Compatibility

Compatible with routers accepting a 0.5 inch shank collet. Rated for use on ABS, Acetal, Acrylic, HDPE, HIPS, Polyethylene terephthalate, Polyvinylchloride, Polycarbonate, Polyethylene, Polypropylene, Polystyrene, and UHMW.

Installation Notes

Installation and bit changes should be performed by a qualified CNC operator or machinist with the router spindle fully powered down and locked out. Ensure the collet and collet nut are clean and free of debris before seating the shank. Do not exceed the router manufacturer's recommended RPM range for the cutter diameter. Inspect the bit for chipping or wear before each use, and replace if carbide edge integrity is compromised.
