Carbide routing end mill

The Onsrud 62-718 is a solid carbide router bit with a downcut O-flute spiral. It is designed for routing operations in hard plastic materials where chip evacuation and a clean top surface are required. The cutter diameter is 3/16 in.

Machinists working with hard plastics

This tool suits CNC operators and fabricators who need a downcut geometry to hold down thin sheets and prevent lifting. It is not for buyers who need an upcut spiral for deep chip removal or a larger cutting diameter for heavy stock removal.

3/16 in cutter diameter

The 3/16 in cutting diameter determines the minimum internal radius and the width of the cut path. Verify that this dimension matches the feature size and toolpath requirements of your specific application.

Questions about this item

How much noise or heat does the 62-718 carbide router bit produce when running continuously in a CNC machine?

The bit itself generates no noise or heat; those come from the spindle and material. Carbide stays sharp longer, reducing friction compared with high-speed steel.

What shank size and collet must I already own to mount the 62-718 downcut O-flute bit?

The cutter diameter is 3/16 in, so you need a 3/16 in collet or an ER collet that accepts that shank. Match the collet to your router or CNC spindle.

Will the 62-718 carbide downcut bit work on the same hard-plastic sheets I currently cut with older high-speed steel bits?

Yes. It is designed for hard plastic and the downcut geometry pushes chips downward, giving a cleaner top edge than upcut HSS bits.
