Cleveland C33244 Square End Mill 3/16 in 4 Flute Hss Ticn

Product Description

The CLEVELAND C33244 is a 4-flute square end mill designed for precision milling operations in ferrous and non-ferrous materials. Manufactured from high speed steel with a titanium carbonitride (TiCN) finish, it offers improved surface hardness and wear resistance over uncoated HSS tooling. The cutter features a 3/16-inch diameter, a 1/2-inch length of cut, and a straight-cylindrical shank with a Weldon flat at 3/8-inch diameter. A 30-degree helix angle and spiral flute geometry promote efficient chip evacuation. This tool is centercutting, allowing direct plunge entry into workpieces without a pre-drilled hole.

The C33244 is suited for milling operations on cast iron, non-ferrous metals, and steel in production and job-shop environments. Its regular-length profile and 2-3/8-inch overall length make it a practical choice for general-purpose slotting, profiling, and side milling on manual mills and CNC machining centers. The right-hand cut and right-hand flute configuration is standard for conventional vertical milling setups. It is typically installed and operated by machinists and tool-and-die professionals.

Key Features

• TiCN coating increases surface hardness and extends tool life compared to uncoated HSS
• Centercutting design allows direct plunge milling without pre-drilling
• 30-degree helix angle with spiral flute geometry for effective chip flow
• Weldon flat on shank provides positive drive and reduces tool pullout
• Right-hand cut and right-hand flute — standard orientation for most milling setups
• Series HG-4C regular-length construction balances rigidity and reach

Compatibility

Designed as an OEM-style replacement or direct-use end mill compatible with standard milling chucks, collet holders, and Weldon-style set-screw tool holders accepting a 3/8-inch shank diameter on manual mills and CNC machining centers.

Installation Notes

Installation should be performed by a qualified machinist following established machine tool safety practices. Ensure the spindle is fully stopped and locked out before mounting or removing the end mill. Seat the shank fully into the holder and tighten the Weldon flat set screw to the tool holder manufacturer's specification. Verify runout with a dial indicator before beginning cutting operations.
