Accupro 12183479 Square End Mill 1/4 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 12183479 is a solid carbide square end mill designed for precision milling operations in metalworking and machining environments. With a 0.250-inch mill diameter, 1-inch length of cut, and 4-inch overall length, this tool delivers accurate material removal in a compact long-reach profile. The micrograin carbide substrate and TiCN coating work together to extend tool life in abrasive and hard-material applications. A 40-degree helix angle promotes efficient chip evacuation and reduces cutting forces, making it well-suited for slotting, profiling, and peripheral milling tasks performed by machinists and tool-and-die professionals.

This end mill is appropriate for use in CNC machining centers and manual knee mills where a 1/4-inch shank diameter is required. The long length-of-cut configuration supports deeper slot milling and side-milling passes without tool changes. Its centercutting geometry allows plunge entry directly into the workpiece. Typical applications include milling of steel alloys, stainless steel, cast iron, and similar ferrous materials in both production-run and job-shop environments.

Key Features

• Solid micrograin carbide construction for hardness and wear resistance
• TiCN finish improves surface hardness and reduces friction during cutting
• 40-degree spiral flute helix angle promotes aggressive chip evacuation
• Centercutting design permits direct plunge milling without a pilot hole
• 4-flute configuration balances chip load and surface finish quality
• Right-hand cut, right-hand flute geometry compatible with standard spindle rotation

Compatibility

Designed as an OEM-style replacement or standard tooling option for CNC machining centers and manual mills accepting a 1/4-inch round shank end mill holder or collet.

Installation Notes

Installation should be performed by a qualified machinist following standard toolroom practices. Ensure the spindle is fully stopped and the machine is powered down before loading or removing the end mill from its holder or collet. Verify collet runout is within acceptable tolerance before beginning a cut, as excessive runout accelerates edge wear on a tool of this diameter. Consult the machine manufacturer and applicable shop safety standards for proper clamping torque and tool-stick-out guidelines.
