Cleveland C75069 Square End Mill

The Cleveland C75069 is a square end mill designed for milling operations in metalworking applications. It suits machinists and maintenance teams who need a general-purpose cutter for slotting and profiling tasks. The tool is manufactured from high speed steel with a TiCN coating for extended wear resistance. It is not intended for buyers who require coolant-through capability or carbide substrate performance.

0.8125 in milling diameter

The critical specification is the 0.8125 in milling diameter which determines the cut width and tool clearance for your specific machining operation. This dimension must match the feature size required by the part drawing or fixture setup. Selecting an incorrect diameter will result in improper fit or excessive material removal. Verify the required cutting diameter against your process documentation before ordering.

High speed steel with TiCN coating

The high speed steel substrate combined with TiCN coating provides a balance of toughness and surface hardness for conventional milling conditions. Heat generation and cutting noise are typical of uncoated high speed steel tools when run at recommended speeds and feeds. Power draw on the machine spindle will vary with depth of cut, material hardness and feed rate selected by the operator. The Weldon flat shank ensures secure clamping in standard holders for stable cutting performance.

Questions about this item

What does the .8125 inch milling diameter mean when the cutter is in the spindle?

The .8125 inch milling diameter is the exact width of cut the tool will produce in the workpiece.

How does the Weldon flat shank interface affect tool holding?

The Weldon flat on the 3/4 inch shank allows a set-screw holder to clamp securely and prevent the end mill from pulling out under load.

What machine clearance is needed for the 1.875 inch length of cut and 4 1/8 inch overall length?

You need at least 1.875 inches of reach below the holder for the cutting zone plus enough Z-travel to accommodate the 4 1/8 inch overall tool length.
