Accupro 39527 Square End Mill 5/8 Inch 3 Flute Powdered Metal

Product Description

The ACCUPRO 39527 is a single-end square end mill designed for milling operations requiring a sharp corner profile and aggressive material removal. Built from powdered metal, this tool delivers consistent edge toughness across a range of ferrous and non-ferrous workpiece materials. The 45-degree helix angle promotes efficient chip evacuation and reduces cutting forces during peripheral and slot milling. With a 5/8 inch cutting diameter, 1-5/8 inch length of cut, and 3-3/4 inch overall length, this end mill suits general-purpose CNC and manual milling applications. It is centercutting, allowing plunge entry directly into the workpiece. The uncoated finish makes it suitable for use with cutting fluids and compatible with regrinding services.

This end mill is intended for use in vertical machining centers, knee mills, and similar setups where a 5/8 inch straight shank is the standard holding interface. The 3-flute configuration balances chip clearance with tool rigidity, making it practical for slotting, profiling, and shoulder milling in job shops and production environments. Machinists and CNC operators working with aluminum, mild steel, and similar materials will find this a reliable general-purpose tool. The right-hand cut and right-hand spiral flute orientation match standard spindle rotation on most milling machines.

Key Features

• 5/8 inch cutting diameter with a 1-5/8 inch length of cut for mid-depth milling operations
• Powdered metal construction provides consistent hardness and edge retention across the tool
• 45-degree helix angle promotes smooth cutting action and effective chip evacuation
• Centercutting design allows direct plunge entry without a pre-drilled pilot hole
• 3-flute spiral geometry balances chip room and core strength for general milling tasks
• Uncoated surface is compatible with standard cutting lubricants and regrinding

Compatibility

Designed as a general-purpose square end mill compatible with standard 5/8 inch end mill holders, collet chucks, and Weldon-style holders used on vertical machining centers and manual knee mills.

Installation Notes

This tool is installed by a machinist or CNC operator using a standard end mill holder or collet sized for a 5/8 inch straight shank. Ensure the spindle is fully stopped and the machine is powered down or in an e-stop state before changing tooling. Verify tool runout with a dial indicator after installation to confirm proper seating. Follow the machine manufacturer and tooling manufacturer guidelines for speed and feed parameters based on workpiece material.
