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.

Questions about this item
How much heat does the .625 in carbide end mill generate during extended milling sessions?
Carbide tools run hotter than high-speed steel; use flood coolant or air blast and reduce feed if the workpiece discolours.
What holder or collet is required for the 5/8 in shank on this end mill?
A 5/8 in ER collet, Weldon flat holder or shrink-fit chuck with matching bore will clamp the straight shank securely.
Will this uncoated 4-flute cutter work in a manual Bridgeport with R8 spindle?
Yes — the 5/8 in straight shank fits an R8 collet, but keep speeds conservative since the tool has no coating for heat resistance.
