Carbide Routing End Mill

This Onsrud 60-172MW is a solid carbide routing end mill built for CNC machining. It uses a compression geometry with a square end and a center-cutting plunge point for clean entry. Right-hand cutting action suits standard spindle rotation. The tool is sold new.

Machinists Needing Compression Cuts

The compression flute design reduces tear-out on the top and bottom faces of laminated or double-sided materials. It is not suited for buyers who need a standard up-cut or down-cut spiral for single-sided chip evacuation. Shops without a rigid CNC router or collet system sized for the shank should look at other tooling.

Center-Cutting Plunge Point

The center-cutting plunge point allows the mill to enter the workpiece directly without a pre-drilled hole or ramp entry. This feature determines whether the tool can start a pocket or slot in the middle of the material. Verify that your tool holder and machine spindle accept the shank configuration before purchasing.

Questions about this item

What shank diameter does the 1/2 inch compression end mill need for a standard collet?

The 1/2 inch shank fits a standard 1/2 inch ER or TG collet; ensure the collet bore matches exactly to prevent runout.

How do you install the carbide compression end mill without damaging the cutting edges?

Insert the shank fully into the collet, tighten the nut to the manufacturer's torque spec, and avoid side-load contact with the flutes during tool changes.

When should the carbide compression end mill be replaced based on wear?

Replace the tool when the compression flutes show visible rounding, chipping, or when cut quality degrades on the 1 5/8 inch length of cut.
