Cleveland HSS End Mill for precision milling

This Cleveland C33389 end mill is a high-speed steel cutting tool designed for general-purpose milling operations. It suits machinists and maintenance technicians who need a reliable square-end cutter for slotting, profiling and facing tasks in a variety of ferrous and non-ferrous materials.

TiN coating and Weldon flat improve tool life

The titanium nitride coating reduces friction and heat buildup, extending edge life compared with uncoated HSS. A Weldon flat on the 3/8 in shank provides positive locking in a standard end-mill holder, preventing pull-out during heavy cuts while allowing quick tool changes.

Verify shank compatibility

Your tool holder must accept a 3/8 in diameter shank with a Weldon flat. The 1.5 in length of cut and 3 1/4 in overall length determine reach, so confirm the machine spindle and workpiece fixture allow sufficient clearance. This cutter is not coolant-through, so external flood or mist coolant must be arranged separately.

Questions about this item

When will the 0.34375 in HSS square end mill need resharpening or replacement?

Resharpen when flank wear becomes visible or cutting forces increase; the high-speed steel body with TiN coating can be reground multiple times by a tool-grinding service.

What limits continuous cutting with the 1.5 in length of cut?

Heat buildup in the high-speed steel and coating degradation are the first limits; without coolant-through capability you must rely on flood or mist cooling to extend tool life.

How much noise, heat and power draw come from running this 3/8 in shank end mill all day?

The cutter itself generates cutting noise and localized heat at the 0.34375 in diameter; spindle power demand depends on material and feed, while the tool body adds negligible vibration.
