Cleveland 33028 HSS End Mill Overview

The Cleveland 33028 is a high-speed steel square end mill built for general-purpose milling tasks. Its 9/64 inch diameter and 7/16 inch length of cut suit slotting and profiling in a range of materials. The uncoated finish keeps costs low for shops that re-sharpen tools regularly. A Weldon flat on the 3/8 inch shank provides secure clamping in standard holders.

Sustained Cutting Behaviour

High-speed steel construction handles interrupted cuts and less rigid setups without chipping, unlike brittle carbide alternatives. The uncoated surface runs cooler when flood coolant is used during longer passes. The 0.4375 inch cutting length allows moderate depth per pass while maintaining tool stability. Chip evacuation remains consistent through the straight flutes during extended operations.

Upgrade Path and Limitations

This tool replaces worn or damaged HSS end mills of the same 0.140625 inch diameter and 3/8 inch shank size. The jump is worth it when the previous cutter shows flank wear or chatter marks on finished walls. It does not suit high-volume production where coated carbide tool life pays off. Buyers needing longer reach or corner-radius profiles should select a different geometry.

Questions about this item

Will the 3/8 in shank fit my existing collet or end-mill holder?

The 3/8 in shank is a standard Weldon flat, so it fits any 3/8 in collet, end-mill holder or drill chuck that accepts a Weldon flat.

Do I need coolant or cutting fluid when running this HSS end mill at full depth?

High-speed steel benefits from cutting fluid or mist coolant, especially at full 7/16 in depth of cut, to manage heat and extend tool life.

Can I use this 9/64 in cutter in a 1/4 in collet with a reducing sleeve?

The shank is 3/8 in, so a 1/4 in collet would need a 3/8 in to 1/4 in reducing sleeve; the cutter will not fit directly.
