YG-1 28573 Square End Mill 3 Flute 1/4 Inch Solid Carbide

Product Description

The YG-1 28573 is a solid carbide, three-flute square end mill designed for precision milling of non-ferrous metals and similar materials. Built from micrograin carbide, it offers a 1/4 inch mill diameter, a 5/8 inch length of cut, and a 2-1/2 inch overall length on a straight cylindrical 1/4 inch shank. The 45-degree helix angle promotes efficient chip evacuation in aluminum, brass, copper, and other non-ferrous workpieces. The bright, uncoated finish is standard for applications where coating interaction with the workpiece material is a concern. Machinists and toolroom technicians install this end mill in CNC machining centers and manual knee mills.

This end mill is suited for slotting, profiling, and peripheral milling operations on non-ferrous metals in both production and job-shop environments. Its right-hand cut and right-hand flute direction are standard for conventional and climb milling passes. The non-centercutting geometry means it is not intended for plunge entry; use a pre-drilled hole or ramping entry strategy instead. The regular length classification keeps it rigid and well-suited for general-purpose work where extended reach is not required.

Key Features

• Micrograin solid carbide construction for hardness and wear resistance in non-ferrous cutting
• 45-degree helix angle promotes aggressive chip evacuation and smooth surface finish
• Three-flute design balances material removal rate with chip clearance
• Bright/uncoated finish appropriate for aluminum and other non-ferrous metals
• Right-hand cut, right-hand spiral for standard milling setups
• Tight mill diameter tolerance of 0.0000 to -0.0005 inches for precise fits and finishes

Compatibility

Designed as an OEM-style solid carbide end mill for use in standard 1/4 inch collets or end mill holders on CNC machining centers and manual milling machines. Primary workpiece material designation is non-ferrous metal.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the spindle before inserting or removing the end mill from the collet or tool holder. Ensure the shank is fully seated and the collet is torqued to the machine manufacturer's specification. Because this tool is non-centercutting, do not program direct plunge moves; use a ramping or helical entry path to begin cuts.
