Cleveland C33124 Square End Mill 0.5in 4 Flute Hss Ticn

Product Description

The CLEVELAND C33124 is a double-end, square-profile end mill designed for metal removal in milling operations across machining centers and manual mills. Built from high speed steel with a titanium carbonitride (TiCN) coating, it delivers improved wear resistance and surface hardness compared to uncoated HSS tooling. The C33124 runs a 0.5-inch cutting diameter with a 1-inch length of cut, a 0.5-inch straight-cylindrical shank (Weldon flat available), and an overall length of 4.5 inches. The 4-flute, right-hand spiral geometry with a 30-degree helix angle balances chip evacuation and finish quality. It is center-cutting, making it suitable for plunge entries and ramping passes.

This end mill is intended for general-purpose milling of cast iron, non-ferrous metals, and steel in production and job-shop environments. The HD-4C series targets applications where tooling durability and reliable performance on ferrous and non-ferrous workpieces are priorities. It is installed and operated by machinists, CNC programmers, and toolroom technicians working in manufacturing, maintenance, and fabrication settings.

Key Features

• Double-end design extends usable tool life by providing two cutting ends per shank
• TiCN coating increases surface hardness and reduces built-up edge on ferrous materials
• Center-cutting geometry allows plunge milling and ramping without a pre-drilled pilot
• 30-degree right-hand spiral flute promotes smooth chip flow and consistent surface finish
• Straight-cylindrical shank with Weldon flat accommodates standard side-lock tool holders
• HD-4C series construction suited for cast iron, non-ferrous metal, and steel stock

Compatibility

Designed as an OEM-style replacement or direct-use tooling for milling applications requiring a 0.5-inch diameter, 4-flute square end mill with a 0.5-inch straight-cylindrical or Weldon flat shank, compatible with standard ER, side-lock, and collet-style tool holders sized for 0.5-inch shanks.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Before changing or seating the tool, confirm the spindle is fully stopped and the machine is in an e-stop or locked-out state per facility lockout/tagout procedures. Seat the shank fully into the holder and torque the set screw against the Weldon flat to the tool holder specification. Inspect the cutting edges for chips or coating damage before use, and verify runout with a dial indicator after clamping.
