Cleveland C81881 Carbide End Mill
The Cleveland C81881 is a 4-flute carbide square end mill designed for general-purpose milling. Its TiAlN coating helps extend tool life during standard machining operations. It suits machinists and fabricators who need a reliable single-end cutter for everyday material removal. The .375 in cutting diameter and 3/8 in shank fit common tool holders.
Practical limits of solid carbide tooling
Solid carbide offers high wear resistance but is brittle compared to high-speed steel. Heavy interrupted cuts or unstable setups can cause chipping or breakage. The non-coolant-through design means chips must be cleared externally with flood coolant or air blast. TiAlN performs best at higher cutting speeds where heat activates the coating.
Check holder and machine rigidity
Verify your collet or end-mill holder accepts a 3/8 in shank with sufficient clamping force. Ensure the machine spindle provides the runout accuracy needed for a .375 in diameter carbide tool. Confirm the 4 in overall length and 1.75 in length of cut suit your workpiece clearance and depth requirements. Rigid workholding is essential to prevent vibration.

Questions about this item
Which diameter or length of cut should I select for this end mill?
This end mill has a 0.375 in milling diameter, a 1.75 in length of cut and a 3/8 in shank diameter.
How does the 1.75 in length of cut perform in a real milling operation?
The 1.75 in length of cut allows deeper profiling and slotting passes before the shank contacts the workpiece.
What does the straight shank interface mean for tool-holding and runout?
The straight 3/8 in shank fits standard collets and end-mill holders, providing secure clamping with minimal runout.
