Cleveland C40058 3-Flute PM+ HSS-E Corner Radius Roughing End Mill 1.25 in .12 in 4 in

Cleveland C40058 Roughing End Mill

The Cleveland C40058 is a 3-flute roughing end mill manufactured from PM+ HSS-E powdered metal with a TiCN coating. It features a 1.25 in milling diameter and a .12 in corner radius for heavy material removal. The tool uses a Weldon flat shank for secure clamping in standard holders. Its 4 in flute length and 6 1/2 in overall length suit deep cavity work.

Machinists Roughing Large Diameter Pockets

This tool suits machinists roughing large diameter pockets or profiles in steel and difficult alloys where the corner radius adds strength. The three-flute design balances chip evacuation with rigidity in slotting operations. Buyers needing a finishing profile or a sharp corner for final dimensions should look at a different geometry. Shops without Weldon flat compatible holders cannot use this shank style.

1.25 Inch Milling Diameter Decides Fit

The 1.25 in milling diameter is the single specification that determines if this cutter fits the programmed tool path and machine capacity. It dictates the maximum width of cut and the minimum corner radius achievable in the workpiece. Verify the spindle power and holder capacity match this diameter before purchase. The .12 in corner radius is fixed and cannot be altered for different fillet requirements.
