Onsrud 52-706 Upcut Spiral Router Bit 0.5in Solid Carbide

Product Description

The ONSRUD 52-706 is a solid carbide upcut spiral router bit designed for precision cutting of plastic and composite materials in CNC routing applications. With a 0.5-inch cutter diameter and a 2.125-inch length of cut, this double-edge bit removes chips efficiently by pulling material upward toward the collet, helping to keep the cut path clear and reduce heat buildup. The 22-degree helix angle promotes smooth chip evacuation and clean edge quality. Right-hand cutting geometry and an uncoated carbide construction make this bit well suited for production routing environments where consistent performance across multiple material types is required.

The 52-706 is used primarily in CNC router applications where operators are cutting plastics and light synthetic materials at production rates. Typical installation scenarios include flat-table and pod-and-rail CNC routing setups in fabrication shops, sign shops, and plastics processing facilities. The upcut flute direction makes this bit effective when workpiece hold-down is secure, as the upward chip pull can lift thin or unsecured stock.

Key Features

• Solid carbide construction delivers hardness and edge retention for abrasive plastic materials
• Upcut flute geometry evacuates chips away from the cut zone, reducing recutting and heat
• 22-degree helix angle promotes smooth, clean edge finishes in plastic substrates
• Double-edge design provides balanced cutting forces and extended tool life
• Uncoated finish is compatible with a wide range of plastic materials without galling risk
• 1/2-inch shank diameter fits standard CNC router collets and tool holders

Compatibility

Designed for routing ABS, Acetal, Extruded Acrylic, Foam, HDPE, Nylon, PE, PET, Polycarbonate, Soft Plastics, Solid Surfaces, and UHMW. Part of the ONSRUD 52-700 series. Fits any CNC router collet accepting a 1/2-inch shank diameter.

Installation Notes

Installation and tool changes should be performed by a qualified CNC operator or machinist with the router 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 to the specified insertion depth. Do not exceed the manufacturer-recommended feed rates and spindle speeds for the material being cut. Secure workpieces firmly before routing, as the upcut flute direction generates upward pulling forces on unsupported stock.
