Cleveland C33774 Square End Mill 17/32 in 2 Flute Hss Tin

Product Description

The CLEVELAND C33774 is a two-flute, single-end square end mill designed for precision milling in ferrous and non-ferrous materials. Built from high speed steel with a titanium nitride (TiN) finish, it delivers extended tool life in applications involving cast iron, non-ferrous metals, and steel. The cutter measures 17/32 inches (0.5313 inches) in diameter with a 1-1/8 inch length of cut and a 1/2 inch straight shank. The 30-degree spiral flute geometry promotes efficient chip evacuation and smooth cutting action. This is a centercutting tool, allowing plunge entry directly into workpiece material. It is part of the HG-2 series and is suited for manual mills and CNC machining centers alike.

The C33774 is a regular-length end mill intended for general-purpose milling tasks on machine shop floors and maintenance operations. It handles slotting, peripheral milling, and plunge cuts in cast iron, steel, and non-ferrous metals. The right-hand cut and right-hand flute configuration is standard for conventional milling setups. The Weldon flat shank option provides a secure toolholder engagement and reduces pullout risk under aggressive feed conditions. Machinists and tool-and-die professionals will find this tool well-suited to production runs and prototype work where consistent geometry and coating durability are required.

Key Features

• High speed steel construction with TiN coating for increased surface hardness and wear resistance
• Centercutting design allows direct plunge entry without pre-drilling
• 30-degree helix angle promotes chip flow and reduces cutting forces
• Straight shank with Weldon flat for positive toolholder retention
• Right-hand cut, right-hand flute — compatible with standard milling setups
• HG-2 series regular-length geometry for versatile general-purpose applications

Compatibility

Designed as an OEM-style replacement and standard tooling option for 1/2 inch collet or end mill holders used in vertical milling machines and CNC machining centers. Primary workpiece materials include cast iron, non-ferrous metals, and steel.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Ensure the spindle is fully powered down and the machine is locked out before changing tooling. Secure the shank firmly in a compatible 1/2 inch end mill holder or collet chuck, engaging the Weldon flat set screw to prevent axial pullout. Verify runout with a dial indicator before commencing cuts, and select feeds and speeds appropriate for the workpiece material and machine rigidity.
