YG-1 GM811030 Square End Mill 4 Flute Solid Carbide 6mm

Product Description

The YG-1 GM811030 is a single-end, square-profile solid carbide end mill designed for precision milling operations in metalworking and machining applications. Built from micrograin carbide, it delivers a hard, wear-resistant cutting edge suited to demanding materials. The tool features 4 flutes with a right-hand cut and right-hand flute direction, providing efficient chip evacuation and smooth surface finishes. The 6 mm shank diameter (0.2362 inches decimal) is a standard metric sizing compatible with collet-style toolholding systems. This end mill is intended for use by machinists and CNC operators in job shop, production, and maintenance machining environments.

The GM811030 is suited for milling slots, pockets, profiles, and contours in ferrous and non-ferrous materials. Its micrograin carbide construction makes it a practical choice for cutting steel, aluminum, and similar workpiece materials at higher speeds and feeds than high-speed steel tooling. The single-end design means the tool is replaced rather than indexed when the cutting edge is worn. Typical install scenarios include CNC machining centers, knee mills, and manual milling machines where a 6 mm collet or end mill holder is available.

Key Features

• Micrograin solid carbide construction for extended tool life and edge retention
• 4-flute geometry for efficient chip removal and improved surface finish
• Right-hand cut and right-hand flute direction for standard milling spindle compatibility
• 6 mm shank diameter (0.2362 inches) fits metric collet systems
• Square end profile for slotting, profiling, and pocket milling
• Single-end design - no indexing required, full replacement when worn

Compatibility

Designed as an OEM-style solid carbide end mill for use in CNC and manual milling machines equipped with a 6 mm collet or compatible end mill holder.

Installation Notes

Installation is performed by machinists using a compatible collet chuck or end mill holder sized for a 6 mm shank. Ensure the spindle is fully powered down and locked out before changing tooling. Seat the shank to the minimum insertion depth specified by the toolholder manufacturer and torque the collet nut to the toolholder specification. Inspect the cutting edges for chips or damage before each use.
