Router bit for straight cuts

The Onsrud 10-78 is a high-speed steel router bit with a single flute and a 1/4 inch cutter diameter. It is designed for straight cutting profiles in fractional inch sizes. The tool suits woodworkers and fabricators who need a basic straight-cutting bit for routing operations.

Single flute clears chips efficiently

The one-flute design helps evacuate material during the cut, which can reduce heat buildup and improve finish quality on softer materials. High-speed steel construction provides a balance of toughness and wear resistance for general-purpose routing tasks. Buyers who need multi-flute bits for faster feed rates or specialised profiles should consider other options.

Questions about this item

Will the HSS flute need resharpening or replacement after heavy routing work?

The high-speed steel flute can be resharpened multiple times; replace it when the edge no longer restores cleanly.

What limits continuous routing with the 1/4 in cutter diameter?

Heat buildup in the high-speed steel flute becomes the limiting factor during prolonged cuts.
