Cleveland C61893 4-Flute Carbide End Mill
The Cleveland C61893 is a square end mill built for general-purpose milling in a workshop or production environment. It suits machinists who need a reliable carbide tool for slotting and profiling operations on ferrous and non-ferrous materials. The uncooked carbide substrate provides hardness and wear resistance for consistent performance. This tool is designed for standard milling machines and CNC setups using a straight shank.
Capacity and headroom with .5 in diameter
The 0.5 in milling diameter and 0.625 in length of cut handle medium-duty material removal in a single pass. The 4-flute design offers increased feed rates and a finer finish compared to fewer flutes when rigidity is sufficient. It runs out on deep-pocket work where the 2 1/2 in overall length limits reach or where chip evacuation in tight corners becomes difficult. Heavy roughing cuts in tough alloys may also exceed the tool's optimal engagement window.
Practical limits of the straight shank interface
The 1/2 in straight shank fits standard collets and end mill holders without adapters. Runout depends entirely on holder quality and spindle condition since the shank has no flats or drive features. The uncoated surface raises friction at higher speeds, limiting surface speed in sticky materials like aluminium or titanium. Non-coolant-through design means external flood or mist is the only cooling option, restricting deep-slotting performance.

Questions about this item
Will this 0.5 in shank fit my older 1/2 in collet without runout?
The shank diameter is 1/2 in, matching standard 0.5 in collets. Carbide construction holds tight tolerances, so it seats cleanly in worn holders if the collet is still round.
How do I verify the 0.625 in length of cut is engaging properly on the first pass?
Measure flute engagement with a depth gauge. Chips should form consistent C-shapes at full 0.625 in depth. Chatter or dust means the tool is rubbing, not cutting.
Does the C61893 come with any coating or coolant hole, or must I supply cutting fluid?
It is uncoated and non-coolant-through. No fluid is included. Supply your own flood or mist coolant for steel; run dry only in easy aluminium.
