Material and application

This Onsrud 60-243 routing end mill is a solid carbide router bit built for spiral upcut work in plastic and wood. The upcut geometry clears chips upward to reduce heat buildup in the cut. It is supplied new and ready for CNC or hand-held routing tasks.

Who it suits and who it does not

Machinists and woodworkers cutting plastic or wood with an upcut spiral will find this bit matches the stated primary material application. Buyers who need a downcut or compression spiral for cleaner top edges, or who work mainly in metal, should look at a different tool geometry.

Cutter diameter

The cutter diameter is 3/8 in, which sets the minimum inside radius and determines the feed and speed range for the job. Verify that your collet or tool holder accepts this shank size before ordering.

Questions about this item

How much heat does the 60-243 carbide bit generate when routing plastic or wood all day?

The solid carbide construction dissipates heat efficiently during continuous upcut spiral routing in plastic and wood, reducing thermal buildup on the 3/8 in cutter diameter.

What collet or chuck size must I already own to run the 60-243?

You need a tool holder that accepts a 3/8 in shank to secure the 60-243 routing end mill in your CNC or hand router.

Will the 60-243 work in an older router that only runs at lower spindle speeds?

The upcut spiral geometry on the 60-243 performs best at standard routing RPMs; slower speeds on legacy machines may reduce chip evacuation in plastic and wood.
