Accupro 12182586 Square End Mill 0.5 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 12182586 is a solid carbide square end mill designed for precision milling operations in metal, composites, and other hard materials. It features a 0.5 inch cutting diameter, a 1 inch length of cut, and a 3 inch overall length with a 0.5 inch shank. The four-flute, right-hand spiral design with a 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. Micrograin carbide construction delivers hardness and edge retention well beyond high-speed steel alternatives. This end mill is centercutting, allowing plunge entry into the workpiece. It is sized for use in CNC machining centers and manual mills in machine shop environments.

This end mill is suited for slot milling, profiling, and peripheral cuts in ferrous and non-ferrous metals in both production and job shop settings. The regular-length geometry fits standard toolholders and collet chucks without extended reach requirements. The uncoated finish makes it a practical choice for applications where regrinding is common or where coolant-based cutting is the standard approach. Machinists working with aluminum, steel, and similar workpiece materials will find this a reliable go-to geometry for general-purpose milling tasks.

Key Features

• Solid micrograin carbide construction for superior hardness and edge retention
• Four flutes with right-hand cut and right-hand spiral flute direction
• 40-degree helix angle for improved chip flow and reduced cutting forces
• Centercutting design enables direct plunge entry into workpiece material
• Mill diameter tolerance of +0.000 / -0.002 inches for consistent fit
• Uncoated finish compatible with coolant-assisted cutting and standard regrind cycles

Compatibility

Designed as an OEM-style replacement and standard tooling option for 0.5 inch collet chucks, end mill holders, and toolholders used in CNC machining centers and manual knee mills requiring a 0.5 inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the collet or toolholder and torque the retaining nut or set screw to the toolholder specification. Verify runout with a dial indicator before beginning a cut, and confirm feed and speed parameters are appropriate for the workpiece material and machine horsepower.
