Cleveland C61023 Square End Mill

This Cleveland C61023 is a two-flute carbide square end mill designed for general-purpose milling operations. It suits machinists and fabricators who need a reliable tool for slotting and profiling in a range of materials. The uncoated carbide substrate provides a balance of hardness and toughness for everyday shop use. It is not intended for high-volume production runs requiring specialised coatings.

.21875 Inch Diameter With .625 Inch Cut Length

The tool offers a milling diameter of .21875 inches and a length of cut of .625 inches, giving sufficient reach for shallow pockets and side milling. The two-flute design allows efficient chip evacuation in softer materials but limits feed rates in harder alloys. Carbide construction resists wear better than high-speed steel but will chip if subjected to heavy interruption. It runs out when deep cavity work exceeds the flute length.

Quarter-Inch Shank For Standard Holders

A straight shank diameter of 1/4 inch fits common ER collets, end mill holders and shrink-fit systems without adapters. The overall length of 2 1/2 inches keeps the tool compact inside tight machine envelopes. Uncoated surfaces require flood or mist coolant to manage heat during extended cuts. The non-coolant-through design means external delivery must be aimed at the cutting zone.

Questions about this item

Will the 1/4 in shank fit the collet I already use on my router?

The end mill has a 1/4 in shank diameter, which matches standard 1/4 in collets used on many routers and milling machines.

How can I confirm the .21875 in cutting diameter is cutting correctly after installation?

Measure the slot or pocket width with a caliper; it should read close to .21875 in if the tool is running true and the machine is rigid.

Does the C61023 come with any coating or coolant accessories, or must I buy those separately?

The tool is uncoated and non-coolant-through; no coating or coolant accessories are included, so any cutting fluid or coated alternative must be purchased separately.
