Accupro 12182827 Square End Mill 19/64 in 4 Flute Carbide

Product Description

The ACCUPRO 12182827 is a solid carbide square end mill designed for precision milling in ferrous and non-ferrous materials. Built to a stub length profile, it features a 19/64 inch (0.2969 inch) cutting diameter, a 1/2 inch length of cut, and a 40-degree helix angle. The spiral flute geometry promotes efficient chip evacuation while the TiCN coating adds surface hardness and heat resistance. With four flutes and a micrograin carbide substrate, this end mill is suited for finish milling and light slotting passes where dimensional accuracy is critical. Licensed machinists and CNC operators install this tool in standard milling chucks or collet holders.

This end mill fits applications in job shop, production machining, and tool room environments. The 5/16 inch shank diameter makes it compatible with standard ER collets and end mill holders commonly found on CNC machining centers and manual knee mills. The centercutting design allows plunge entry into the workpiece, adding versatility for pocketing and ramping operations. The right-hand cut and right-hand flute configuration is standard for conventional CNC spindle rotation. Stub length geometry reduces deflection and improves rigidity in tight-clearance setups.

Key Features

• Solid micrograin carbide construction for wear resistance and edge retention
• TiCN coating increases surface hardness and reduces built-up edge
• 40-degree helix angle promotes smooth chip flow and reduced cutting forces
• Centercutting capability allows direct plunge entry
• Stub length (2 inch OAL) maximizes rigidity and minimizes deflection
• Right-hand cut, right-hand spiral flute — standard CNC spindle compatible

Compatibility

Designed as a direct-fit replacement or standard tooling selection for 5/16 inch shank end mill holders and ER collet chucks used on CNC machining centers and manual milling machines.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Always power down and lock out the machine spindle before changing tooling. Seat the shank fully into the collet or end mill holder to the recommended grip depth before torquing the retention nut. Verify runout with a dial indicator after installation and before initiating a cut to confirm proper seating and tool concentricity.
