Cleveland C39659 HSS End Mill

The Cleveland C39659 is a high-speed steel square end mill designed for general milling operations. It features a 1-inch milling diameter and a Weldon flat shank for secure tool holding in standard tool holders. This uncoated tool suits workshops performing slotting, profiling, and face milling on ferrous and non-ferrous materials.

Machinists needing a 1.875 in length of cut

This cutter suits machinists who need a 1.875 in length of cut with a 3/4 in shank diameter for rigid setups. It is not for operations requiring coolant-through capability or coated tooling for high-temperature alloys. Buyers needing extended reach or neck relief should look at alternative tool geometries.

1.875 in cut length with 4 1/8 in overall length

The 1.875 in cut length handles medium-depth slots and profiles in a single pass on manual or CNC mills. The 4 1/8 in overall length provides standard clearance for vise-held workpieces. It runs out on deep-pocket work exceeding the flute length or on abrasive materials that wear uncoated HSS rapidly.

  • 875 in cut length enables deep profiling passes

Questions about this item

What size collet or holder do I need for the 3/4 in shank on this C39659 end mill?

The tool has a 3/4 in shank with a Weldon flat, so use a 3/4 in Weldon-compatible holder or a 3/4 in collet that accepts flats.

Will this 1 in diameter cutter fit in a mill that only accepts 3/4 in shank tools?

Yes — the cutting diameter is 1 in while the shank is 3/4 in, so it mounts in any machine that takes a 3/4 in shank.

How do I confirm the 1.875 in length of cut is fully engaged after setup?

Measure from the tip to the shank transition; the fluted portion should be 1.875 in long and the overall length 4 1/8 in.
