Onsrud 56-164 Square End Router Bit 1/2 Inch Solid Carbide

Product Description

The ONSRUD 56-164 is a 2-flute, square end, double edge router bit designed for high-performance routing of hard plastics and composite materials. Built from solid carbide, this bit features a 1/2 inch cutter diameter, a 2.125 inch length of cut, and a 6 inch overall length. The straight flute geometry and right-hand cutting direction deliver clean, consistent cuts across a wide range of thermoplastics and engineered surfaces. It is used by CNC machinists, fabricators, and tooling technicians working in production and custom shop environments.

This router bit is suited for routing ABS, acetal, acrylic, fiberglass, foam, nylon, polyvinylchloride (PVC), phenolic, and solid surface materials. It fits into standard 1/2 inch collet router setups and is well matched to both CNC router tables and hand-guided router applications where a square end profile and full double edge engagement are required. It is part of the ONSRUD 56-000P series, which targets demanding, multi-material routing tasks in industrial and fabrication settings.

Key Features

• Solid carbide construction for durability and edge retention in hard materials
• Square end geometry produces flat-bottomed cuts and clean edge profiles
• Double edge router style maximizes material removal per pass
• Straight flute design promotes chip clearance and smooth surface finish
• Right-hand cutting direction compatible with standard spindle rotation
• Non-piloted design allows full operator control of cut path

Compatibility

Designed for use with 1/2 inch collet routers and CNC spindles. Rated for use on ABS, acetal, acrylic, fiberglass, foam, nylon, polyvinylchloride, phenolic, and solid surface workpiece materials as specified by the manufacturer.

Installation Notes

Installation and tooling changes should be performed by a qualified machinist or CNC technician with the router or spindle fully powered down and locked out per applicable safety procedures. Ensure the collet and collet nut are clean and free of debris before seating the shank. Verify runout after installation and confirm that spindle speed is appropriate for the workpiece material and bit diameter before beginning a cut.
