Roughing End Mill for Heavy Material Removal
The Cleveland C40011 roughing end mill is a 3-flute powdered metal HSS-E tool built for aggressive stock removal in milling operations. Its special profile geometry breaks chips efficiently during deep cuts. The uncoated finish suits general-purpose ferrous and non-ferrous applications. Machinists choose this cutter for high-volume roughing passes.
Powdered Metal Construction Handles Heat and Load
Powdered metal HSS-E substrate retains hardness at elevated temperatures generated by heavy chip loads. The 3-flute design balances chip evacuation with tool rigidity during extended cuts. An uncoated surface avoids coating delamination risks in abrasive or sticky materials. Weldon flat shank ensures secure torque transmission in standard holders.
1-Inch Shank Fits Standard Weldon Holders
A 1-inch diameter shank with Weldon flat locks directly into common end-mill holders without adapters. Four-inch length of cut reaches deep cavities while 6-1/2-inch overall length provides clearance for fixture interference. No neck diameter means full shank strength behind the flutes. Unsuitable for finishing passes requiring fine surface finish or tight tolerances.

Questions about this item
How is the 1 in shank with Weldon flat installed in a milling holder, and what step is often missed?
Insert the shank fully into a Weldon-compatible holder, then tighten the set screw onto the flat; the step often missed is confirming the flat aligns with the screw before torquing.
What maintenance or replacement will the uncoated powdered-metal flutes need later?
The flutes will dull with use; plan to resharpen or replace the end mill once cutting edges show wear or chip load drops.
What limit appears first during sustained cuts with the 4 in length of cut?
Tool deflection and heat buildup in the uncoated flutes typically become the limiting factors before the 6 1/2 in overall length is reached.
