Cleveland 30732 roughing end mill

This Cleveland 30732 roughing end mill is a 4-flute cobalt tool with 8% cobalt content. It has a .5 in milling diameter, 3 in length of cut and 5 in overall length. The uncoated design features a Weldon flat shank of 1/2 in for secure holder grip. It is built for heavy material removal in milling operations.

Suited for high-volume roughing in steel

Machinists running aggressive roughing passes in steel, stainless steel or high-temperature alloys will benefit from the coarse tooth geometry and cobalt substrate. The tool is not for finishing work where a fine surface finish is required. It also lacks coolant-through capability, so shops dependent on through-tool coolant should look elsewhere.

.5 in milling diameter with 3 in length of cut

The .5 in cutting diameter and 3 in length of cut define the maximum width and depth of cut in a single pass. These dimensions decide whether the tool fits the pocket or profile geometry of the specific job.

Questions about this item

Will the 0.5 in shank fit my older Weldon holder without an adapter?

Yes, the 0.5 in shank includes a Weldon flat that matches standard holders for that shank size.

How can I confirm the cobalt tool is cutting correctly once installed?

Listen for a steady, lower-pitched chatter and check that chips are thick and blue-tinged, showing the 8% cobalt edge is shearing properly.

Does the 30732 come with any coating or coolant hardware, or must I buy those separately?

The mill is uncoated and non-coolant-through, so no coating or coolant fittings are included; purchase those separately if needed.
