Cleveland C32633 Square End Mill 0.5 Inch 4 Flute Cobalt Ticn

Product Description

The CLEVELAND C32633 is a 4-flute cobalt square end mill designed for high-performance milling in demanding materials. Built from M42 cobalt high-speed steel and finished with a TiCN coating, it delivers extended tool life when cutting high-temperature alloys, stainless steel, and general-purpose steel. The 0.5 inch diameter cutter features a 30-degree helix angle and spiral flute geometry that promotes chip evacuation and reduces heat buildup at the cutting zone. Centercutting capability allows for plunge entry without a pre-drilled pilot hole. This tool is installed and operated by machinists and CNC programmers working in production and job-shop environments.

The C32633 is suited for milling operations on high-temperature alloys, stainless steel, and steel workpieces where tool durability and finish quality are critical. Its regular-length profile and straight cylindrical shank with Weldon flat accommodate standard end mill holders and set-screw collet chucks. The 1.25 inch length of cut provides adequate engagement depth for shoulder milling, slotting, and profiling passes in ferrous and heat-resistant materials. Applications span aerospace component machining, die and mold work, and general precision metalworking.

Key Features

• M42 cobalt construction for elevated red hardness and wear resistance in difficult-to-machine alloys
• TiCN coating reduces friction and extends cutting edge life versus uncoated tooling
• 30-degree helix angle with spiral flutes promotes smooth chip flow and reduces chatter
• Centercutting design enables direct plunge milling without a pilot hole
• Right-hand cut, right-hand flute configuration compatible with standard CNC and manual milling setups
• Weldon flat on shank provides positive drive and resists tool pullout under aggressive feeds

Compatibility

Designed for use in standard 0.5 inch end mill holders, set-screw holders, and Weldon-style collet chucks. Rated for primary workpiece materials including high-temperature alloys, stainless steel, and steel (material codes M, P, S). Part of the CLEVELAND HGC-4C series.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures and machine tool manufacturer guidelines. Secure the Weldon flat against the set screw in the holder to prevent axial pullout during cutting. Verify runout with a dial indicator after clamping before initiating a cut. Always confirm spindle speed, feed rate, and depth of cut are appropriate for the workpiece material before engaging the cutter.
