Cleveland C81818 Carbide End Mill

The Cleveland C81818 is a four-flute carbide square end mill designed for general-purpose milling in a workshop or light production environment. Its solid carbide construction provides hardness and wear resistance for cutting steel, cast iron and non-ferrous alloys. The TiAlN coating reduces friction and extends tool life at higher cutting speeds. It suits machinists and maintenance teams needing a reliable single-end cutter.

0.125 inch diameter with 0.25 inch length of cut

The milling diameter is 0.125 in and the length of cut is 0.25 in, which determines the maximum slot depth and profile reach in a single pass. The 1/8 in shank matches standard ER11 or 1/8 in collets and holders. Overall length is 1 1/2 in, giving a compact profile for tight machine envelopes. Select this tool when the job calls for these exact cutting dimensions.

Fits 1/8 inch shank holders

The straight shank with no neck relief fits directly into 1/8 in collets, shrink-fit holders or Weldon flats without adapters. Non-coolant-through design means no internal passages to clog, simplifying coolant management on machines without through-spindle supply. The short overall length reduces gauge-line protrusion, freeing Z-axis travel and improving rigidity on smaller VMCs or router spindles.

Questions about this item

How does the .125 in milling diameter affect slot width in a real cut?

The .125 in milling diameter produces a slot width of .125 in when the tool is run at full engagement, giving a direct match between cutter size and finished slot.

What does the TiAlN coating allow for in terms of cutting speed and heat resistance?

The TiAlN coating increases surface hardness and heat resistance, enabling higher cutting speeds and longer tool life in steel and hardened alloys compared with uncoated carbide.

Will the 1/8 in shank fit a standard ER11 collet or 1/8 in end-mill holder?

Yes, the 1/8 in shank diameter matches standard ER11 collets and 1/8 in end-mill holders, so it clamps directly without adapters.
