Cleveland C33787 Square End Mill 7/8 in 2 Flute Hss Tin

Product Description

The CLEVELAND C33787 is a square end mill designed for material removal and profile milling in machine tool applications. Built from high speed steel (HSS) with a titanium nitride (TiN) coating, this tool offers improved surface hardness and wear resistance over uncoated HSS. It runs a 2-flute configuration with a 30-degree spiral helix and a 7/8 inch cutting diameter, providing good chip evacuation in a range of workpiece materials. The centercutting geometry allows for plunge entry as well as conventional milling passes. This end mill fits standard milling machines, CNC machining centers, and manual knee mills used in job shop and production environments.

The C33787 is suited for cutting cast iron, non-ferrous metals, and steel. The straight cylindrical shank with Weldon flat accepts standard milling chuck holders and Weldon-style collets. Its regular length designation makes it a practical general-purpose choice for setups where extended reach is not required. Machinists and toolroom operators select this series for finish and semi-finish passes where tool life and surface quality matter.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Seat the Weldon flat securely against the set screw in the holder to prevent tool pullout under cutting loads. Verify runout with a dial indicator after installation before taking the first cut.
