Accupro 12177419 Square End Mill 0.5in 6 Flute Solid Carbide

Product Description

The ACCUPRO 12177419 is a 6-flute, solid carbide square end mill built for high-performance milling in demanding shop environments. With a 0.5 inch cutting diameter, 1.25 inch length of cut, and a 45-degree helix angle, it delivers efficient chip evacuation and smooth cutting action across a wide range of materials. The micrograin carbide substrate provides the hardness and edge retention needed for rigorous production work. Centercutting geometry allows plunge milling as well as conventional peripheral cutting. The bright, uncoated finish suits applications where coating interaction with the workpiece material is a concern.

This end mill is suited for use in CNC machining centers and manual mills performing slotting, profiling, and pocket milling operations. The 6-flute configuration increases feed rates compared to 4-flute designs while maintaining surface finish quality, making it well-suited for finishing passes and semi-finishing in steel, stainless, and similar materials. The 0.5 inch shank diameter fits standard ER and side-lock toolholders commonly found in production environments.

Key Features

• 6-flute spiral geometry with 45-degree helix for efficient chip evacuation and reduced cutting forces
• Solid micrograin carbide construction for enhanced hardness and edge retention
• Centercutting design enables direct plunge entry without pre-drilling
• Right-hand cut, right-hand flute configuration for standard spindle operation
• Bright, uncoated finish suitable for a variety of workpiece materials
• Mill diameter tolerance of +0.000 / -0.002 inches for consistent fit and finish

Compatibility

Designed as a standard 0.5 inch shank square end mill compatible with ER collet chucks, Weldon side-lock holders, and other 0.5 inch bore toolholding systems used in CNC and manual milling machines.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and the machine in a safe, de-energized state. Verify that the toolholder bore and collet are clean and free of debris before seating the shank. Torque toolholder clamping hardware according to the toolholder manufacturer specifications, not the end mill specifications. Confirm runout with a dial indicator before beginning the cut to protect both the tool and the workpiece.
