Value Collection 720-4028 Square End Mill 5/16 in 4 Flute Hss

Product Description

The VALUE COLLECTION 720-4028 is a double-end, 4-flute square end mill manufactured from M2 high speed steel. With a 5/16-inch cutting diameter and a 3/4-inch length of cut, it handles slotting, profiling, and peripheral milling operations in general-purpose machining environments. The matching 3/8-inch shank diameter and 3-1/2-inch overall length make it compatible with standard collet chucks and end mill holders. The bright, uncoated finish is suited for cutting softer steels, aluminum, and non-ferrous materials where coating is not required. Machinists and tool-and-die professionals are the primary installers of this tooling.

This end mill is intended for use in vertical machining centers, knee mills, and manual milling machines where fractional-inch tooling is standard. The double-end design allows both ends to be used before the tool is retired, which extends service life and reduces tooling cost per operation. The right-hand cutting and right-hand flute direction are conventional for standard spindle rotation. A 30-degree helix angle provides a balance between chip evacuation and cutting edge strength, making it appropriate for a range of general-purpose milling tasks on ferrous and non-ferrous workpieces.

Key Features

• Double-end design allows use of both cutting ends, maximizing tool life
• M2 high speed steel construction provides toughness and wear resistance in general-purpose applications
• 30-degree helix angle balances chip evacuation with edge stability
• 4-flute spiral geometry suited for finishing passes and controlled material removal
• Bright/uncoated finish compatible with a wide range of workpiece materials
• Right-hand cut and right-hand flute direction for standard spindle use

Compatibility

Designed as an OEM-style replacement or standard tooling option for fractional-inch collet chucks and end mill holders accepting a 3/8-inch shank diameter in vertical machining centers and manual knee mills.

Installation Notes

This tooling should be installed by a qualified machinist following standard tool-holding procedures. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Use a properly sized collet or end mill holder torqued to the machine manufacturer's specification. Verify runout with a dial indicator after installation to confirm proper seating before beginning a cut.
