YG-1 GM811902 Square End Mill 4 Flute Solid Carbide

Product Description

The YG-1 GM811902 is a single-end, 4-flute square end mill manufactured from micrograin solid carbide. Solid carbide construction provides superior hardness and heat resistance compared to high-speed steel, making it suitable for cutting ferrous and non-ferrous metals, alloys, and plastics. The 0.2362-inch (6.00 mm) shank diameter fits standard collet chucks and tool holders of that bore size. Right-hand cut and right-hand flute direction are the conventional configuration for standard CNC and manual milling operations. This tool is designed for machinists, toolmakers, and maintenance shops requiring precise square-shoulder profiling, slotting, and peripheral milling.

This end mill is suited for general-purpose milling applications in job shops, production machining environments, and maintenance facilities. The 4-flute geometry balances chip evacuation with surface finish quality, making it appropriate for finishing passes and light-to-moderate material removal in steel, stainless, aluminum, and similar workpiece materials. The fixed helix and fixed index design deliver consistent, predictable cutting behavior in both CNC machining centers and manual knee mills.

Key Features

• Micrograin solid carbide construction for extended tool life and edge retention
• 4-flute geometry suited for finishing and moderate stock removal
• 0.2362-inch (6.00 mm) shank diameter for standard collet compatibility
• Right-hand cut and right-hand flute direction for conventional milling
• Single-end design for straightforward tool changes
• Fixed helix and fixed index for predictable, stable cutting performance

Compatibility

Designed for use with standard collet chucks, end mill holders, and tool holders accepting a 6.00 mm (0.2362-inch) shank. Suitable for CNC machining centers and manual milling machines configured for right-hand rotation.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Power down and lock out the machine spindle before inserting or removing the tool from the holder. Ensure the shank is fully seated and the collet or set-screw holder is torqued to the machine manufacturer's specification. Inspect the cutting edges for chips or wear before each use and replace the tool if edge condition is compromised.
