Cleveland Cobalt Double-End Mill 5/8

This Cleveland Cobalt double-end mill measures 5/8 inch in diameter with four flutes and a 30-degree helix angle. The TiCN coating increases surface hardness and reduces wear during finishing passes. A 1-3/8 inch length of cut and 5 inch overall length suit standard tool-holders. It is ground for right-hand cutting in general-purpose milling.

Best for finishing in steel and alloys

Machinists who need a durable cobalt tool for light finishing cuts in ferrous materials will benefit from the coated flutes. The double-end design provides two cutting ends per holder. Shops that require roughing geometry, variable helix, or specialised corner radii should select a different tool. High-feed or deep-slotting strategies are outside this cutter's intended range.

TiCN coating extends tool life in finishing

The titanium carbonitride finish lowers friction and resists built-up edge when profiling or facing at recommended speeds. This single attribute determines whether the mill matches the application. Without the coating the substrate would wear faster in the same conditions. Buyers who need uncoated cobalt or a different substrate should look elsewhere.

Questions about this item

Does this double-end mill need a 5/8-inch collet or holder to fit the shank?

Yes, the shank diameter is 5/8 inch, so the tool holder or collet must match that size for secure clamping.

Will the 30-degree helix angle and TiCN finish work well in the same setup as older uncoated high-speed steel cutters?

The 30-degree helix and TiCN coating run at higher speeds and resist heat better than uncoated HSS, so adjust feeds and speeds accordingly when mixing them.

How can I confirm the 4-flute cobalt mill is cutting correctly once installed?

Check for a smooth surface finish, consistent chip formation and no chatter; the 0.000-inch corner radius should leave a sharp square corner on the workpiece.
