Onsrud 63-724 Upcut Spiral Router Bit 1/4 in Solid Carbide

Product Description

The ONSRUD 63-724 is a single-edge upcut spiral router bit machined from solid carbide for cutting hard plastics and solid surface materials. The upcut flute geometry pulls chips up and out of the cut, reducing heat buildup and helping keep the workpiece clear of debris. The bit measures 0.25 inches in cutter diameter with a 0.375-inch length of cut, a 1/4-inch shank diameter, and a 2-inch overall length. At 21 degrees of helix angle, this single-flute design balances chip evacuation with surface finish quality. It is uncoated and suited for right-hand cutting rotation on CNC routers and handheld router setups used by fabricators and woodworking professionals.

This bit is designed for routing acrylic, nylon, PVC, polycarbonate, and solid surface materials. It performs well in light-duty profiling, slotting, and contour cutting passes where clean edges and efficient chip clearing are priorities. The 1.625-inch shank length provides solid tool holding in standard 1/4-inch collets. Fabricators working with plastic sheet goods and solid surface countertop materials will find this bit suitable for both full-depth and multi-pass cutting strategies.

Installation Notes

Installation and use should be performed by experienced machinists, CNC operators, or skilled fabricators familiar with router tooling and safe operating procedures. Power down and lock out the router or CNC spindle fully before installing or removing the bit. Inspect the bit for chipping or wear before each use and replace if damage is found. Follow the router or CNC machine manufacturer guidelines for collet torque and spindle speed settings appropriate to the material being cut.
