Cleveland C30835 Roughing End Mill

This 4-flute cobalt 8% roughing end mill is built for aggressive material removal in milling operations. The .75 inch cutting diameter and Weldon flat shank suit CNC machines and manual mills where heavy chip loads are required.

Replaces general-purpose end mills

The cobalt substrate and roughing geometry outperform standard high-speed steel tools when cutting tough alloys or taking deep cuts. The upgrade is worth it when cycle time matters and tool changes must be minimised.

Sustained load behaviour

Four flutes and the uncoated cobalt body dissipate heat during long passes without coolant-through capability. The 1.625 inch length of cut and 3 7/8 inch overall length maintain rigidity in extended reach situations.

Questions about this item

What shank diameter does the C30835 need in a tool holder?

The cutter uses a 3/4 in Weldon flat shank, so the holder must accept a .75 in diameter with a flat for the set screw.

How should the end mill be seated to avoid pull-out?

Align the Weldon flat with the holder’s set screw, tighten the screw firmly on the flat, then verify zero run-out before cutting.

When does this cobalt rougher need to be replaced?

Replace the tool when the four flute edges show visible chipping, excessive flank wear, or when surface finish degrades beyond tolerance.
