Accupro 12182409 Square End Mill 0.1772 in 4 Flute Carbide

Product Description

The ACCUPRO 12182409 is a solid carbide square end mill designed for precise milling operations in metal, composites, and engineered plastics. With a 0.1772 inch (4.50 mm) cutting diameter and a 0.6299 inch (16.00 mm) length of cut, this tool handles slotting, profiling, and peripheral milling in small-feature applications. The micrograin carbide substrate supports harder workpiece materials and maintains edge integrity under demanding cutting conditions. Four spiral flutes at a 40-degree helix angle promote efficient chip evacuation and reduce cutting forces. This end mill is installed and run by machinists and tool-and-die professionals on CNC machining centers and manual mills.

This end mill is suited for light to medium material removal in ferrous and non-ferrous applications where a small-diameter, high-precision cutting tool is required. The regular length profile and 6.00 mm (0.2362 inch) shank diameter make it compatible with standard ER collet chucks and end mill holders commonly found in production and job shop environments. The centercutting geometry allows plunge entry, expanding its usefulness in pocketing operations.

Key Features

• Micrograin solid carbide construction for improved hardness and wear resistance
• 40-degree helix angle with spiral flute geometry for efficient chip evacuation
• Centercutting design allows direct plunge entry into workpiece material
• Right-hand cut and right-hand flute configuration for standard spindle use
• Mill diameter tolerance of +0.000 / -0.002 inches for consistent, predictable sizing
• Uncoated finish suitable for use with cutting fluids on a range of workpiece materials

Compatibility

Designed as an OEM-style replacement and standard production end mill for use in CNC machining centers and manual mills accepting a 6.00 mm shank diameter via ER collet or end mill holder systems.

Installation Notes

Installation should be performed by a qualified machinist. Secure the shank fully within the collet or tool holder to the manufacturer-specified engagement depth before tightening. Verify runout with a dial indicator before beginning a cut. Always bring the spindle to a complete stop before changing or inspecting the tool.
