Cleveland 39093 HSS End Mill Specifications

The Cleveland 39093 is a high-speed steel square end mill with a .75 inch milling diameter and a 2.25 inch length of cut. It features a TiN coating and a Weldon flat shank for secure tool holding. This new cutting tool is intended for general-purpose milling operations in a workshop or production environment. It suits machinists and maintenance teams who need a reliable non-coolant-through cutter for slotting and profiling tasks.

Thermals Noise and Power Draw

As a solid rotary cutting tool, the Cleveland 39093 generates heat at the cutting interface during milling, which is managed through the TiN coating and appropriate cutting parameters. It produces noise typical of high-speed steel end mills engaging workpiece material at operational spindle speeds. Power consumption is determined entirely by the machine tool's spindle drive and the specific feed and speed rates selected by the operator for the material being cut.

Build Quality and Day-to-Day Use

The end mill is constructed from high-speed steel with a titanium nitride coating to enhance wear resistance and tool life. Its Weldon flat shank ensures a positive, non-slip grip in standard Weldon-style end mill holders, simplifying tool changes on manual or CNC machines. The non-coolant-through design means external flood or mist coolant must be directed at the cut zone when required by the application. The 4 1/2 inch overall length and .75 inch shank diameter provide standard rigidity for the specified cutting length.

Questions about this item

How do I install the Cleveland 39093 HSS end mill in my milling machine, and what step is commonly missed?

Insert the 3/4 in Weldon flat shank into a matching Weldon holder and tighten the set screw onto the flat; the step often missed is aligning the flat precisely with the screw so the tool cannot spin under load.

What maintenance or replacement will the Cleveland 39093 HSS end mill need over time?

The TiN coating and high-speed steel cutting edges will wear; plan to resharpen or replace the tool when the 0.75 in diameter shows reduced cut quality or the 2.25 in length of cut no longer meets tolerance.

What limit appears first when running the Cleveland 39093 HSS end mill continuously in steel?

Heat buildup in the non-coolant-through design is the first limit; without through-tool coolant the 2.25 in flute length traps chips and temperature rises faster than in coolant-fed tools.
