Precision carbide alignment tool

The Onsrud 65-025 is a solid carbide router bit designed for precise alignment work in aluminium, MDF, plastic and wood. Its Super Spiral O-Flute geometry supports clean chip evacuation and accurate edge quality for CNC operators and professional woodworkers who need repeatable results.

Solid carbide construction and shank fit

The full-carbide body resists wear and deflection during extended routing cycles, maintaining dimensional stability across the listed materials. A standard shank diameter allows direct mounting in common collets and tool holders, so the bit can be swapped quickly without specialised adapters or proprietary interfaces.

Thermal stability and cutting efficiency

Carbide construction dissipates cutting heat effectively, reducing the risk of material melting or tool degradation during continuous passes. The O-Flute spiral promotes smooth chip flow, which lowers cutting forces and audible noise while keeping power draw consistent throughout the operation.
