Cleveland C61031 End Mill

The Cleveland C61031 is a 2-flute carbide square end mill designed for general-purpose milling operations. It suits machinists and fabricators who need a reliable cutting tool for slotting, profiling and plunge cuts in a variety of workpiece materials. The solid carbide construction provides hardness and wear resistance for extended tool life in demanding shop environments. This cutter is intended for professionals and serious hobbyists running milling machines or CNC routers.

Uncoated Carbide Performance

The uncoated carbide substrate delivers sharp cutting edges straight from the package without a coating layer that can alter edge geometry. This allows clean shearing in non-ferrous metals, plastics and softer steels where coating adhesion or buildup might be a concern. The straight shank and non-coolant-through design keep the tool simple and compatible with standard collet holders and end mill adapters. No additional software or accessories are bundled with this single cutting tool.

Standard Shank Installation

The 1/4 inch shank diameter fits directly into common ER collets, Weldon flats or shrink-fit holders used on most manual and CNC mills. Installation is a matter of securing the shank to the correct run-out tolerance and setting the 1.5 inch length of cut within the workpiece envelope. The main risk is excessive tool deflection or chatter if the 6 inch overall length is used with deep pockets without proper support or reduced stick-out. Proper feeds and speeds for the specific material prevent premature wear or breakage.

Questions about this item

When will the 0.25 in carbide cutting edges need to be resharpened or replaced?

Resharpen or replace the 0.25 in carbide flutes when cutting edges dull, chip, or when finish quality drops; solid carbide allows multiple regrinds before full replacement.

What limit appears first during a long cut with the 1.5 in length of cut?

Chip evacuation in the 1.5 in flute length and tool deflection in the 6 in overall length typically limit sustained cuts before the carbide itself fails.

How much heat and noise does the uncoated carbide generate in a full-day milling run?

Uncoated carbide runs hotter than coated versions; expect noticeable heat at the 0.25 in cutting zone and standard router-level noise during continuous operation.
