Cleveland C39714 Square End Mill 9/16 in 3 Flute Hss Ticn

Product Description

The CLEVELAND C39714 is a 3-flute, single-end square end mill designed for material removal in ferrous and non-ferrous machining operations. Built from high speed steel with a TiCN (Titanium Carbonitride) finish, it delivers improved surface hardness and wear resistance compared to uncoated HSS tooling. The cutting diameter measures 9/16 inches with a 1/2 inch straight-cylindrical shank featuring a Weldon flat for positive tool retention. Length of cut is 1-3/8 inches and overall length is 3-3/8 inches. The 30-degree helix spiral flute geometry promotes efficient chip evacuation. This tool is center-cutting, allowing plunge entry into a workpiece.

The C39714 belongs to the CLEVELAND HG-3 series and is suited for milling cast iron, steel, and non-ferrous metals in both manual and CNC machining centers. Right-hand cut and right-hand flute orientation make it compatible with standard spindle configurations. It is a regular-length tool appropriate for face milling, slotting, profiling, and pocketing operations where moderate reach is required. Machinists and tool-and-die tradespeople will find it well-suited for general-purpose shop work across a broad range of workpiece materials.

Key Features

• TiCN coating increases surface hardness and extends tool life versus uncoated HSS
• 3-flute geometry balances chip clearance with rigidity for versatile material compatibility
• Center-cutting design permits direct plunge entry without pre-drilled pilot holes
• 30-degree helix angle aids chip evacuation in spiral flute configuration
• Weldon flat on straight-cylindrical shank reduces tool pullout under heavy cuts
• Right-hand cut and right-hand flute for use with standard CNC and manual spindles

Compatibility

Designed for use in standard 1/2 inch end mill holders, collet chucks, and Weldon-style side-lock holders. Primary workpiece materials include cast iron, non-ferrous metals, and steel per CLEVELAND HG-3 series specifications.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Use a calibrated torque wrench on the Weldon flat set screw to secure the shank without overtightening. Verify tool runout with a dial indicator after installation before beginning a cut.
