Accupro 12179539 Square End Mill 4 Flute Solid Carbide

Product Description

The ACCUPRO 12179539 is a solid carbide square end mill designed for precision milling operations in metalworking and machining environments. It features a 0.5 inch cutting diameter, a 0.625 inch length of cut, and a 2.5 inch overall length with a 0.5 inch shank diameter. The four-flute geometry with a 30-degree helix angle and AlTiN coating supports aggressive material removal while maintaining tool life in ferrous and hardened materials. This is a centercutting, right-hand cut, right-hand flute configuration in a stub length profile. It is sold and installed by machinists and CNC operators in job shop and production environments.

This end mill is suited for slotting, profiling, and contouring operations on machining centers and manual mills. The stub length format provides added rigidity and reduced deflection, making it appropriate for applications where tool overhang must be minimized. The AlTiN finish improves performance in dry or high-speed cutting conditions, particularly on alloy steels, stainless steels, and cast iron. It is a single-end tool with coarse pitch flute spacing.

Key Features

• Solid carbide construction for rigidity and wear resistance
• AlTiN coating for extended tool life in high-temperature cutting conditions
• 4-flute, coarse pitch design for efficient chip evacuation
• 30-degree helix angle balances cutting force and surface finish
• Centercutting capability allows plunge entry into workpiece
• Stub length profile minimizes deflection in tight-clearance setups

Compatibility

Designed as a standard shank square end mill compatible with 0.5 inch collets, end mill holders, and milling chucks used on vertical and horizontal machining centers or manual knee mills.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and the tool holder is clean and free of chips before seating the shank. Verify runout with a dial indicator after tightening to confirm proper seating in the holder. Follow the machine tool manufacturer guidelines for speeds and feeds based on workpiece material and depth of cut.
