Onsrud 65-010 Upcut Spiral Router Bit 1/8 in Solid Carbide

Product Description

The ONSRUD 65-010 is a single-edge upcut spiral router bit machined from solid carbide and designed for precise, clean cutting in aluminum, plastics, solid surfaces, and wood. It features a 0.125-inch cutter diameter, a 0.25-inch length of cut, and a 0.25-inch shank diameter, making it well suited for fine detail routing and tight-tolerance profiling. The right-hand cutting direction and 21-degree helix angle work together to pull chips upward and away from the cut zone, reducing heat buildup and improving cut quality. This bit is uncoated and ships ready to install.

This router bit is built for use in CNC routers and handheld routing applications where a compact cutter diameter is required. Its solid carbide construction holds up well in both production and prototype environments. Typical users include woodworkers, sign makers, plastics fabricators, and machinists routing non-ferrous metals such as aluminum. The 1.75-inch shank length provides stable tool holding in standard collet chucks.

Key Features

• Solid carbide construction for rigidity and extended edge life
• Upcut flute geometry evacuates chips away from the workpiece surface
• 21-degree helix angle reduces cutting forces and heat in soft metals and plastics
• Single-edge design allows for aggressive chip load in softer materials
• Right-hand cutting direction compatible with standard spindle rotation
• Uncoated finish suitable for aluminum, plastics, solid surfaces, and wood

Compatibility

Designed as an OEM-style routing tool for CNC routers and handheld routers accepting a 0.25-inch shank collet. Part of the ONSRUD 65-000 series.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Power down and lock out the spindle before changing tooling. Seat the shank fully into the collet to the manufacturer-recommended insertion depth before tightening. Verify spindle speed and feed rate are appropriate for the material being cut before beginning a pass.
