Cleveland C31198 5-Flute Cobalt Roughing End Mill
This roughing end mill is built for heavy material removal in milling operations. The 5-flute cobalt construction provides wear resistance when cutting tough metals. It suits machinists and shops that need aggressive stock removal on manual or CNC mills.
Weldon flat shank limits holder compatibility
The tool uses a Weldon flat on a 1 in shank, so it only fits holders designed for that flat. It cannot be clamped in plain round-shank collets or shrink-fit holders without an adapter. The non-coolant-through design also rules out through-spindle coolant delivery.
1 in diameter with 3 in length of cut
The milling diameter is 1 in and the length of cut is 3 in, giving a 3:1 reach-to-diameter ratio. This single dimension decides whether the tool can reach the full depth of your pocket or slot in one pass.
Highlights

Questions about this item
Is the 5-flute cobalt design better than a 4-flute for heavy roughing?
Five flutes on cobalt tooling give more cutting edges per revolution, which increases material-removal rate and reduces chatter in deep 3-inch cuts compared with typical four-flute roughers.
How does the 1-inch milling diameter perform in a standard Weldon holder?
The 1-inch shank with Weldon flat seats securely in any matching Weldon holder, so the full 3-inch length of cut is supported without slippage during aggressive roughing passes.
Does the uncoated cobalt limit the tool to dry machining only?
Uncoated 8 % cobalt handles dry and flood-coolant roughing equally well; the substrate resists heat buildup up to the full 5-1/2-inch overall length without requiring a coating.
