Cleveland C33395 Square End Mill 5/8 in 4 Flute Hss Tin

Product Description

The CLEVELAND C33395 is a 4-flute, single-end square end mill designed for general-purpose milling in steel, cast iron, and non-ferrous metals. Built from high speed steel with a titanium nitride (TiN) finish, it offers improved surface hardness and wear resistance over uncoated HSS tooling. The cutter measures 5/8 inch in diameter with a 2-1/2 inch length of cut and a 4-5/8 inch overall length. It features a right-hand cut, right-hand spiral flute, and a 30-degree helix angle. The centercutting geometry allows for plunge entry into the workpiece. This tool is installed and operated by machinists and CNC or manual mill operators in production and maintenance shop environments.

The C33395 belongs to the Cleveland HG-4C series and is suited for milling operations on steel, cast iron, and non-ferrous materials in both production and toolroom settings. The straight cylindrical shank with Weldon flat accommodates standard end mill holders and set-screw-style toolholders. Its regular-length classification makes it a practical choice for general-depth slotting, profiling, and peripheral milling where extended reach is not required.

Key Features

• 4-flute spiral design for improved chip evacuation and surface finish in ferrous and non-ferrous cuts
• TiN coating increases surface hardness and extends tool life over bare HSS
• 30-degree helix angle balances cutting force and chip flow for general-purpose work
• Centercutting geometry permits direct plunge milling without a pre-drilled pilot hole
• Right-hand cut and right-hand flute configuration suits standard CNC and manual milling setups
• Weldon flat shank provides positive drive and reduces pullout risk in high-load cuts

Compatibility

Designed for use in standard end mill holders and set-screw toolholders accepting a 5/8 inch straight shank with Weldon flat. Suitable for milling steel, cast iron, and non-ferrous metals as indicated by primary workpiece material codes P, K, and N.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and power is locked out before changing tooling. Seat the Weldon flat against the holder set screw and torque to the toolholder manufacturer specification. Verify runout with a dial indicator before beginning a cut to prevent premature tool wear or workpiece damage.
