Cleveland C39713 End Mill

The Cleveland C39713 is a three-flute high-speed steel end mill built for general-purpose milling in ferrous and non-ferrous metals. Its centre-cutting geometry allows plunge cuts as well as side milling, while the TiCN coating reduces friction and extends tool life. Machinists and maintenance technicians will find it suited for slotting, profiling and pocketing operations.

TiCN Coating Limits

The TiCN coating improves wear resistance and allows higher cutting speeds than uncoated HSS, yet it remains a high-speed steel substrate rather than carbide. Hardened steels above moderate hardness, high-temperature alloys and highly abrasive composites will wear the flutes quickly, so the tool is not intended for those materials. Dry cutting or insufficient coolant can also degrade the coating prematurely.

Replaces Uncoated HSS Mills

This cutter replaces standard uncoated high-speed steel end mills when longer edge life or slightly higher feed rates are needed. The upgrade is worthwhile for shops running repeated production slots or profiles in mild steel, aluminium or brass where tool changes cost downtime. It does not substitute for carbide tooling in high-speed or hard-material applications.

Questions about this item

Should I pick the 0.5 in milling diameter or a different size for my job?

This end mill has a fixed 0.5 in milling diameter with a 1.25 in length of cut and 3 1/4 in overall length; choose it when those dimensions match your slot or profile requirements.

What does the 0.5 in milling diameter mean once the tool is in the machine?

It defines the width of cut the three-flute high-speed steel cutter will produce in a single pass, with a 1/2 in shank that fits standard Weldon flat holders.

How does the Weldon flat shank interface affect tool holding and run-out?

The 1/2 in shank with a Weldon flat locks into a set-screw holder, providing positive drive and reducing pull-out risk during heavy side loads.
