Cleveland C61904 carbide end mill
The Cleveland C61904 is a four-flute carbide square end mill built for general-purpose milling in ferrous and non-ferrous materials. Its solid carbide construction provides the rigidity and wear resistance that machinists and maintenance shops expect from a reliable cutting tool.
Half-inch diameter with 1.5-inch length of cut
A .5-inch cutting diameter and 1.5-inch length of cut give enough reach for medium-depth pockets and profiling passes without excessive deflection. The 6-inch overall length and matching 1/2-inch shank fit standard ER collets and Weldon holders, while the uncoated surface limits the tool in high-heat or abrasive alloys where a coating would extend life.
Uncoated carbide runs hotter in sustained cuts
Without a protective coating the flutes generate more heat during heavy radial engagement, so flood coolant or frequent air blast is advisable for prolonged roughing. The straight, non-coolant-through design relies entirely on external lubrication, and carbide’s brittleness means interrupted cuts or unstable setups can chip the edges faster than coated alternatives.

Questions about this item
Will the 1/2 in shank on the C61904 fit the collet on my older Bridgeport mill?
The end mill has a 1/2 in shank diameter, which matches standard 1/2 in collets and end mill holders found on many manual and CNC mills.
How can I verify the 4-flute carbide cutter is performing correctly once installed?
Check for consistent chip formation, minimal vibration, and a smooth surface finish on the workpiece; the 1.5 in length of cut should engage cleanly in a single pass.
Does the C61904 come with any tool holder, coating option, or coolant accessories in the package?
The box contains only the uncoated carbide square end mill itself; tool holders, collets, and coolant delivery components are sold separately.
