Value Collection 720-4350 Square End Mill 4 Flute Hss

Product Description

The VALUE COLLECTION 720-4350 is a double-end, four-flute square end mill designed for general-purpose milling operations in metal fabrication and machining environments. Manufactured from M2 high speed steel with a bright uncoated finish, this tool features a 0.1719-inch (11/64-inch) cutting diameter and a 0.875-inch length of cut. The 30-degree spiral flute geometry and right-hand cut with right-hand flute direction support efficient chip evacuation across a range of ferrous and non-ferrous materials. A centercutting design allows plunge entry without a pre-drilled pilot hole, making it suitable for slotting, profiling, and pocket milling tasks.

This end mill fits standard CNC machining centers, knee mills, and manual milling machines using a 3/16-inch collet or matching tool holder. The long-series configuration and 3.25-inch overall length provide additional reach for deeper pocket work and stepped-feature machining. The double-end design delivers two usable cutting ends per tool, extending service life between replacements. Machinists and tool-and-die technicians working in job shops, maintenance, and light production environments will find this tool applicable to a wide range of everyday milling tasks.

Key Features

• M2 high speed steel construction for toughness and wear resistance across common workpiece materials
• Double-end design provides two cutting ends, doubling usable tool life per piece
• Centercutting geometry allows direct plunge milling without a starter hole
• 30-degree helix angle promotes smooth cutting action and chip flow
• Bright uncoated finish — no coating buildup to affect close-tolerance fitment
• Right-hand cut and right-hand flute for use in standard spindle-direction setups

Compatibility

Designed for use in milling machines and machining centers equipped with a 3/16-inch collet, end mill holder, or equivalent toolholding system accepting a 0.1875-inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's toolholding procedures. Ensure the spindle is fully stopped and locked out before inserting or removing the end mill from the collet or holder. Verify runout with a dial indicator after seating the shank, as excessive runout accelerates tool wear and reduces surface finish quality. Always confirm spindle direction matches the right-hand cut geometry of this tool before engaging the workpiece.
