Accupro 12183644 Square End Mill 1/4 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 12183644 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. With a 0.25 inch mill diameter and a 1.5 inch length of cut, this tool handles slotting, profiling, and peripheral milling in demanding materials. The TiCN (titanium carbonitride) coating improves surface hardness and wear resistance compared to uncoated carbide. The micrograin carbide substrate supports higher cutting speeds and finer edge retention. At 6.0 inches overall length, this is an extra-long configuration suited for deep-reach operations where standard-length end mills cannot access the workpiece. Licensed machinists and CNC operators are the primary users of this tool.

This end mill fits common CNC machining centers, vertical mills, and manual milling machines accepting a 0.25 inch shank. The extra-long 6.0 inch OAL makes it appropriate for deep-cavity milling, mold and die work, and applications requiring extended reach into pockets or fixtures. The centercutting geometry allows plunge entry directly into the workpiece. Right-hand cut and right-hand flute configuration is standard for conventional spindle rotation in most machining setups.

Key Features

• TiCN finish for increased wear resistance and reduced friction at the cutting edge
• Micrograin solid carbide construction for edge sharpness and rigidity at high cutting speeds
• 40-degree helix angle promotes efficient chip evacuation and reduced cutting forces
• Centercutting design allows direct plunge milling without pre-drilling
• 4-flute spiral configuration balances material removal rate with surface finish quality
• Extra-long 6.0 inch OAL provides deep-reach capability for cavities and hard-to-access features

Compatibility

Designed for use in CNC machining centers and manual milling machines with a 0.25 inch collet or tool holder accepting a 0.25 inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before inserting or removing the end mill from the tool holder. Use a properly sized collet or end mill holder and verify runout with a dial indicator before cutting. Follow the tooling manufacturer and machine manufacturer guidelines for appropriate feed rates and spindle speeds based on workpiece material.
