Cleveland C33248 Square End Mill 1/4 in 4 Flute Hss Ticn

Product Description

The CLEVELAND C33248 is a 4-flute square end mill designed for precision material removal in ferrous and non-ferrous machining applications. Built from high speed steel (HSS) and coated with titanium carbonitride (TiCN), it delivers improved wear resistance and surface hardness compared to uncoated HSS tooling. The 1/4 inch cutting diameter and 5/8 inch length of cut (LOC) suit it for slotting, profiling, and peripheral milling in tight-tolerance work. The 30-degree helix angle promotes smooth chip evacuation and reduces cutting forces. This is a single-end, center-cutting tool — it can plunge directly into a workpiece. It belongs to the Cleveland HG-4C series.

This end mill is rated for primary use on cast iron, non-ferrous metals, and steel. The 3/8 inch straight-cylindrical shank with Weldon flat accommodates standard end mill holders and set-screw-style tool holders commonly found on vertical milling machines and CNC machining centers. The regular-length geometry makes it a practical choice for general-purpose milling where extended reach is not required. Machinists and tool-and-die professionals working in job shop, production, and maintenance environments will find this a reliable fit for everyday milling tasks.

Key Features

• TiCN coating improves surface hardness and wear resistance over uncoated HSS
• Center-cutting design allows direct plunge entry into workpiece material
• 30-degree right-hand spiral helix promotes efficient chip evacuation
• 4-flute configuration balances material removal rate with chip clearance
• Weldon flat on shank prevents tool pullout in set-screw holders
• Rated for cast iron, non-ferrous metal, and steel workpiece materials

Compatibility

Designed as an OEM-style replacement or direct-use tool for standard 3/8 inch end mill holders, collet chucks, and Weldon-style set-screw holders on vertical mills and CNC machining centers.

Installation Notes

Installation should be performed by a qualified machinist. Ensure the spindle is fully stopped and power is locked out before inserting or removing tooling. Seat the shank fully into the holder and torque set screws to the tool holder specification. Verify tool runout with a dial indicator before cutting, as excessive runout accelerates TiCN coating wear and reduces tool life.
