Cleveland C39587 Square End Mill 0.5in 3 Flute Hss

Product Description

The CLEVELAND C39587 is a double-end, three-flute square end mill manufactured from high speed steel (HSS). Designed for material removal in milling operations, it features a 0.5-inch cutting diameter, a 1-inch length of cut, and a 4.125-inch overall length. The spiral flute geometry and 30-degree helix angle promote efficient chip evacuation and smooth cutting action. Right-hand cut and right-hand flute orientation are standard. The uncoated HSS construction suits general-purpose milling where coating is not required. This tool is installed and operated by machinists and tool-and-die professionals using standard milling machines or CNC machining centers.

The C39587 is suited for milling cast iron, non-ferrous metals, and steel in both conventional and CNC milling setups. Its regular-length profile fits standard tool holders and collets accepting a 0.5-inch straight cylindrical shank with a Weldon flat. The centercutting design allows plunge entry directly into the workpiece, making it practical for slot milling, pocket milling, and peripheral cuts in a shop or production environment.

Key Features

• Double-end design extends usable tool life by providing two cutting ends
• Three-flute spiral geometry balances chip clearance and cutting edge strength
• 30-degree helix angle improves chip flow and surface finish on ferrous and non-ferrous materials
• Centercutting capability allows direct plunge cuts without pre-drilling
• Straight cylindrical shank with Weldon flat for positive tool holder retention
• Uncoated HSS construction suitable for general-purpose shop use and regrinding

Compatibility

Compatible with milling machines and CNC machining centers accepting a 0.5-inch straight cylindrical shank with Weldon flat. Rated for primary workpiece materials including cast iron, non-ferrous metals, and steel per material codes K, N, and P. Series HD-3.

Installation Notes

Installation is performed by a qualified machinist following standard toolroom procedures. Secure the shank in a collet or end mill holder rated for the shank diameter before operation. Verify spindle speed and feed rate are appropriate for the workpiece material and depth of cut before engaging the tool. Never exceed the manufacturer-rated length of cut range of 1.0 to 1.25 inches.
