Cleveland C33697 Square End Mill 0.25in 2 Flute Hss Ticn

Product Description

The CLEVELAND C33697 is a double-end square end mill designed for precision milling operations in metal fabrication and machining environments. Manufactured from high speed steel with a titanium carbonitride (TiCN) finish, it delivers extended tool life and improved wear resistance compared to uncoated HSS tooling. The cutting end measures 0.25 inches in diameter with a 0.5-inch length of cut, while the 0.375-inch straight-cylindrical shank with Weldon flat provides secure tool holding. The two-flute, right-hand spiral design at a 30-degree helix angle promotes efficient chip evacuation. This end mill is center-cutting, allowing direct plunge entry into workpiece material. It is installed by machinists and CNC operators in shop and production environments.

The C33697 belongs to the Cleveland HD-2 series and is suited for milling cast iron, non-ferrous metals, and steel. Its regular-length geometry at 3.375 inches overall length makes it a practical choice for standard-depth slotting, profiling, and pocketing operations on manual mills and CNC machining centers. The double-end configuration extends usable tool life by providing two cutting ends per tool.

Key Features

• High speed steel construction with TiCN coating for improved hardness and wear resistance
• Center-cutting design allows direct plunge milling without pre-drilling
• 30-degree helix angle spiral flutes promote chip evacuation and reduce heat buildup
• Double-end design provides two usable cutting ends per tool
• Right-hand cut and right-hand flute configuration for standard CNC and manual mill setups
• Weldon flat on straight-cylindrical shank reduces slippage under cutting loads

Compatibility

Designed for use with cast iron, non-ferrous metals, and steel workpieces. Compatible with standard 0.375-inch collet or end mill holder systems on CNC machining centers and manual knee mills. Part of the Cleveland HD-2 series for regular-length milling applications.

Installation Notes

Install and removal of end mills should be performed by qualified machinists with the spindle fully powered down and locked out. Ensure the tool holder collet or set screw engages the Weldon flat securely before operation. Verify runout with a dial indicator after mounting to confirm proper seating. Follow applicable shop safety standards and machine manufacturer guidelines for tool change procedures.
