Cleveland C61049 Carbide End Mill

The Cleveland C61049 is a solid carbide square end mill built for general-purpose milling in ferrous and non-ferrous materials. Its uncoated surface suits shops that prefer to apply their own coatings or run short production batches without coating cost.

35-degree helix for chip evacuation

The 35-degree helix angle improves chip evacuation compared with lower-helix tools, reducing re-cutting and heat buildup in deeper slots. Upgrading from a straight-flute or low-helix cutter is worthwhile when chip packing limits feed rates or surface finish.

Straight 7/16 in shank fits standard holders

The straight 7/16 in shank seats directly in common ER collets, Weldon flats or milling chucks without adapters. The most common issue is insufficient shank engagement — ensure the holder clamps past the flute run-out to prevent pull-out under heavy radial loads.

Questions about this item

Will the 7/16 in shank fit my 7/16 in collet or end-mill holder?

Yes, the shank diameter is 7/16 in, so it matches a standard 7/16 in collet or holder.

How do I install this end mill without damaging the carbide flutes?

Tighten the collet or set screw on the 7/16 in shank only; never clamp on the fluted section or the carbide will crack.

When should I replace this uncoated carbide end mill?

Replace it when the 35° cutting edges show visible chipping, excessive flank wear, or when surface finish deteriorates.
