Cleveland C60425 Carbide End Mill 47 deg 7/32 in SHK pneumatic accessory

Cleveland C60425 Carbide End Mill

The Cleveland C60425 is a solid carbide square end mill designed for milling operations. Its 47 degree helix angle supports efficient chip evacuation in a range of materials. The 7/32 inch shank diameter fits standard collets and holders used in pneumatic and power tool setups. This accessory suits machinists and maintenance teams needing a durable, uncoated cutter for general-purpose profiling and slotting.

Practical limits of the 47 degree helix

A 47 degree helix reduces cutting forces and improves surface finish compared to lower angles, but it increases axial thrust that the tool holder must resist. The uncoated carbide substrate handles heat well yet wears faster in abrasive alloys than coated alternatives. Non-coolant-through design means external flood or mist coolant is required for deep pockets or high metal removal rates. The .75 inch length of cut limits the maximum depth per pass without multiple steps.

Build quality and shank implications

Solid carbide construction provides high rigidity, reducing deflection during side milling compared to high-speed steel equivalents. The straight shank with a 1/4 inch diameter ensures secure clamping in ER collets, Weldon flats or shrink-fit holders without a neck relief to interfere. An overall length of 2 1/2 inches keeps the tool compact for tight machine envelopes while maintaining reach for shallow cavities. Uncoated finish avoids coating delamination risks in sticky materials like aluminium or copper.

Not for buyers needing coated performance

Shops requiring TiAlN, AlTiN or diamond-like coatings for high-temperature alloys or graphite should select a coated variant. Applications demanding longer flute lengths or reduced shank diameters for deep cavity access cannot use this geometry. Users reliant on through-tool coolant for chip evacuation in blind holes must choose a coolant-through design. The fixed .21875 inch cutting diameter does not suit operations needing larger or smaller profile sizes.
