Cleveland C61911 4-Flute Carbide Square End Mill .625 in

Cleveland C61911 End Mill Overview

The Cleveland C61911 is a 4-flute carbide square end mill built for general-purpose milling tasks. Its .625 in cutting diameter and 5/8 in shank suit standard tool holders in CNC and manual machines. The uncoated carbide substrate handles ferrous and non-ferrous materials alike. Machinists needing a reliable single-end tool for slotting and profiling will find it practical.

Sustained Cutting Behaviour

The solid carbide construction resists deflection during extended cuts, keeping the 2.25 in length of cut engaged without chatter. Four flutes evacuate chips efficiently in both slotting and side-milling passes, reducing heat buildup in the workpiece. The straight, non-coolant-through design relies on external flood or mist coolant for temperature control. Operators can maintain consistent feed rates across long production runs.

Shank and Length Constraints

The 5/8 in shank diameter fits common ER collets and Weldon holders without adapters, while the 5 in overall length reaches deep cavities without excessive overhang. Users requiring longer reach or coolant-through capability must select a different tool series. The uncoated surface limits tool life in abrasive alloys compared to coated alternatives. Shops running high-speed aluminium may prefer a polished-flute geometry instead.
