Cleveland C33689 End Mill Application

This Cleveland C33689 HSS end mill is a square-profile milling cutter made from high-speed steel with a TiCN coating. It features a 0.125 in milling diameter and a 0.375 in length of cut. The 3/8 in shank has a Weldon flat for secure clamping in compatible holders. Overall length measures 3 1/16 in for standard tooling setups.

Suited For General Milling Tasks

Machinists performing slotting, profiling or pocketing in steel, cast iron or non-ferrous metals will find this tool appropriate. The TiCN coating adds wear resistance for moderate production runs. Shops needing longer reach, corner radii or carbide-grade performance should evaluate other tool geometries instead.

Critical Specification: 0.125 Inch Cutting Diameter

The 0.125 in diameter determines the minimum feature size and slot width this cutter can produce. Verify that your part geometry and machine rigidity match this dimension before purchase. The 0.375 in length of cut defines the maximum depth per pass in a single operation.

Questions about this item

What size collet or chuck is needed for the 3/8 in shank diameter of the C33689 end mill?

A 3/8 in collet or chuck is required to hold the 3/8 in shank of this end mill securely.

Can the C33689 end mill be used with a standard 1/2 in collet if I use a reducing sleeve?

Yes, a 3/8 in to 1/2 in reducing sleeve allows the 3/8 in shank to fit a standard 1/2 in collet.

How do I verify the TiCN coating on the C33689 is intact and the tool is cutting correctly after setup?

Inspect the flutes for a uniform grey-violet colour and run a test cut; consistent chip formation and a smooth finish confirm proper operation.
