Cleveland C75039 Square End Mill

The Cleveland C75039 is a high-speed steel square end mill built for general-purpose milling operations. It suits machinists and maintenance teams who need a reliable cutter for slotting, profiling and facing in ferrous and non-ferrous materials.

Practical limits of high-speed steel tooling

High-speed steel offers good toughness and lower cost than carbide but wears faster at high cutting speeds and elevated temperatures. The uncoated surface provides no additional heat or wear resistance, so tool life drops sharply in abrasive alloys or high-speed passes without effective flood coolant.

1.5 inch milling diameter with 4 inch length of cut

The 1.5 inch cutting diameter paired with a 4 inch length of cut defines the maximum depth and width of material removed in a single pass. Shops needing larger diameters, longer reach or coated performance for high-production runs should select a different tool.

Highlights

  • 5 in milling diameter for wide material removal
  • 4 in length of cut enables deep profiling
  • High speed steel construction resists wear in general machining
  • Uncoated surface suits non-ferrous and low-heat applications

Questions about this item

Which Cleveland end mill should I choose for a 1.5 inch milling diameter?

The C75039 model provides a 1.5 inch milling diameter with a 4 inch length of cut and 1 1/4 inch shank diameter, made from uncoated high speed steel for general milling tasks.

What does the 1.5 inch milling diameter mean when the tool is in the machine?

A 1.5 inch milling diameter removes a 1.5 inch wide path per pass, so the spindle must deliver enough torque for that width of cut in your material.

What does the Weldon flat shank cap in practice?

The Weldon flat on the 1 1/4 inch shank allows secure clamping in a matching end mill holder, preventing the tool from spinning under heavy milling loads.
