1.5 in Square End Mill

The Cleveland C75086 is a 6-flute HSS square end mill with a 1.5 in milling diameter. It features a TiCN coating for extended tool life and a Weldon flat shank for secure clamping. The length of cut is 1.375 in with an overall length of 3 5/8 in. The shank diameter is 3/4 in.

Machining professionals and CNC operators

This tool suits machinists profiling or slotting in ferrous materials where a rigid, high-flute-count cutter improves finish. Buyers needing coolant-through capability or a different shank style should look at other options. The non-coolant-through design limits internal chip evacuation in deep cavities.

6-flute HSS with TiCN coating

The six-flute high-speed steel construction with TiCN coating determines feed rates and wear resistance in steel and cast iron. This geometry reduces chip load per tooth for finer finishes at higher speeds. Verify your machine holder accepts a 3/4 in Weldon flat shank before ordering.

Questions about this item

How do I install the 6-flute HSS square end mill with its Weldon flat shank, and what step do people often miss?

Insert the 3/4 in shank into a compatible Weldon holder and tighten the set screw onto the flat; the step often missed is verifying the set screw seats fully on the flat to prevent pull-out during heavy cuts.

What maintenance or replacement will this 1.5 in milling diameter end mill need later?

The high-speed steel cutting edges will dull with use; plan to resharpen or replace the tool once flank wear reaches the point where surface finish or dimensional tolerance on the 1.375 in length of cut degrades.

What limit shows up first when running this TiCN-coated end mill continuously in steel?

Heat buildup at the cutting zone typically appears first, accelerating edge wear on the 6-flute geometry before the TiCN coating loses its hardness advantage.
