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.

Questions about this item
Does the Cleveland C40058 end mill include any holders or tooling accessories in the box?
The Cleveland C40058 end mill is supplied as the cutting tool only; holders, collets or other tooling accessories must be purchased separately.
When should I choose the 1.25 in diameter with 0.12 in corner radius over other available sizes?
Select the 1.25 in diameter and 0.12 in corner radius when your operation requires that specific milling diameter and corner profile for the workpiece material and finish required.
How does the 4 in length of cut affect reach and rigidity in a milling setup?
The 4 in length of cut provides extended reach for deeper pockets while the 3-flute PM+ HSS-E construction with Weldon flat helps maintain rigidity during heavy roughing passes.
