Cleveland C40350 Square End Mill

This Cleveland C40350 square end mill is a powdered-metal milling cutter with a .75 inch cutting diameter and a 3 inch length of cut. It features an uncoated finish and a Weldon flat on a 3/4 inch shank for secure tool-holder clamping. The overall length measures 5 1/4 inches. Machinists use it for general-purpose slotting and profiling in ferrous and non-ferrous materials.

Build integration and clearance

The Weldon flat shank fits standard 3/4 inch end-mill holders, so the tool installs directly without collets or adapters. Its 3 inch flute length provides deep reach for pocketing, while the uncoated substrate allows economical resharpening when edges dull. Builders needing coated tools for high-temperature alloys or longer reach than 3 inches will need a different cutter.

Highlights

  • .75 in milling diameter for precise slotting
  • powdered-metal substrate resists wear in steel
  • 3 in length of cut reaches deep pockets
  • Weldon flat shank locks securely in holders

Questions about this item

How long can the 3 in length of cut be used before tool deflection becomes the limiting factor?

The 3 in length of cut on this 0.75 in diameter powdered metal end mill will reach its deflection limit first in deep slots or heavy radial engagement; reduce axial depth or step-over to maintain accuracy.

Does the uncoated powdered metal flute design run hotter or louder than coated carbide when milling steel all day?

Uncoated powdered metal generates more heat and wear in continuous steel milling than coated carbide, so expect higher cutting temperatures and the need for flood coolant to control thermal expansion.
