Value Collection 720-3305 Square End Mill 3/8 in 4 Flute Hss

Product Description

The VALUE COLLECTION 720-3305 is a single-end, square-profile end mill designed for general-purpose milling operations in metal fabrication and machining environments. Built from M2 high speed steel with a bright/uncoated finish, it offers reliable performance across a range of ferrous and non-ferrous materials. The 3/8-inch cutting diameter is matched by a 3/8-inch shank diameter, making it compatible with standard collet and end mill holders. With a 1-1/2-inch length of cut and a 3-1/4-inch overall length, this long-series tool provides the reach required for deeper pockets and slots without sacrificing rigidity. Right-hand cutting and right-hand spiral fluting are standard on this tool.

This end mill is suited for use in knee mills, CNC machining centers, and manual vertical mills handling slot milling, peripheral milling, and profile cuts. The 30-degree helix angle promotes smooth chip evacuation during conventional and climb milling operations. The 4-flute configuration balances material removal rate with surface finish quality, making it a practical choice for finish passes and moderate stock removal in shop environments. Centercutting geometry allows plunge entry, adding to the tool's versatility on the floor and in production settings.

Key Features

• M2 high speed steel construction for durability across a broad range of workpiece materials
• 4-flute spiral design with 30-degree helix angle for balanced chip evacuation and surface finish
• Centercutting geometry permits direct plunge entry without a pre-drilled hole
• Bright/uncoated finish suitable for use with cutting fluids and general-purpose applications
• Long-series length type provides additional reach for deeper pocket and slot work
• Right-hand cut and right-hand flute direction compatible with standard spindle rotation

Compatibility

Designed as a standard fractional-inch shank end mill for use in collet chucks, end mill holders, and milling machine spindles accepting 3/8-inch shank tooling.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's setup procedures. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank to the minimum recommended engagement depth in the holder and verify runout with a dial indicator before cutting. Always apply appropriate cutting fluid or coolant for the workpiece material being machined.
