Cleveland 80274 Double End Mill
The Cleveland 80274 is a 4-flute carbide square double end mill designed for general-purpose milling operations. It suits machinists and maintenance technicians who need a versatile cutting tool for slotting, profiling and plunge cuts in a range of materials. The TiAlN coating adds wear resistance and helps extend tool life during dry machining. Its double-ended geometry provides two cutting ends per holder, reducing tool-change frequency.
Thermals Noise And Power Draw
As a solid carbide rotary cutter, the tool generates heat only through material removal and friction at the cutting edges. TiAlN coating reduces thermal buildup by lowering the coefficient of friction, allowing higher speeds without coolant. No electrical power is drawn by the cutter itself; all energy comes from the machine spindle. Noise levels depend entirely on the machine tool, workpiece fixturing and cutting parameters selected by the operator.
Build Fit And Clearance
The end mill has a 0.15625 in cutting diameter and a 3/16 in straight shank that fits standard ER, collet or Weldon holders. Overall length is 2 in with a 0.3125 in length of cut, so it reaches shallow pockets without excessive overhang. Non-coolant-through design means no through-spindle coolant passages are required in the holder. The square profile leaves a flat-bottomed feature, and the double-ended format frees a tool station when the first end wears.

Questions about this item
How do I install the 0.15625 in diameter carbide end mill in my tool holder, and what step is often missed?
Use a collet or holder that matches the 3/16 in shank diameter. The step often missed is fully seating the shank so the 0.3125 in length of cut clears the workpiece without the holder contacting the part.
What maintenance or replacement will the TiAlN coated carbide tool need later?
The TiAlN coating wears over time. Replace the tool when the cutting edges show chipping or when the coating is visibly worn, as the carbide substrate cannot be economically re-coated.
What limit appears first during sustained cutting with the 2 in overall length double-end mill?
Heat buildup in the carbide body is the first limit. The non-coolant-through design and 0.15625 in diameter restrict chip evacuation, so cutting edges overheat before deflection becomes an issue.
