Value Collection 720-3003 Square End Mill 1/8 in 4 Flute Hss

Product Description

The VALUE COLLECTION 720-3003 is a single-end, four-flute square end mill designed for general-purpose milling operations in metal, plastic, and composite materials. It is manufactured from M2 high speed steel with a bright uncoated finish, making it well suited for lower-speed applications where lubrication is applied manually. The cutting diameter is 0.125 inches with a 0.375-inch length of cut and a 0.375-inch shank diameter. Overall length is 2.3125 inches. The 30-degree right-hand spiral flute geometry promotes efficient chip evacuation while maintaining edge stability in conventional milling passes.

This end mill is used in manual milling machines, knee mills, and benchtop CNC machines for slotting, profiling, and peripheral milling on ferrous and non-ferrous workpieces. Its regular length classification keeps it rigid under cutting load, reducing deflection during light-to-medium finishing passes. Machinists, tool-and-die makers, and maintenance technicians performing small-bore milling work will find the 1/8-inch diameter appropriate for fine detail work and narrow slot cutting. It is not center-cutting and should not be used for direct plunging into solid stock.

Key Features

• M2 high speed steel construction provides good toughness and wear resistance at moderate cutting speeds
• Four right-hand spiral flutes with a 30-degree helix angle for balanced chip flow and surface finish
• Bright uncoated finish suited to lubricated cutting environments
• Regular length design maximizes rigidity and minimizes deflection on short-reach cuts
• Single-end configuration with a 0.375-inch shank diameter for standard collet and end mill holder fitment
• Not center-cutting — designed for peripheral and slotting operations, not plunge entry

Compatibility

Designed as a standard fractional-inch shank end mill compatible with 3/8-inch collets, end mill holders, and ER-style collet chucks used on manual and CNC milling machines.

Installation Notes

Installation and tool changes should be performed with the machine powered off and the spindle at a complete stop. Use a properly sized collet or end mill holder matched to the 0.375-inch shank diameter and tighten to the toolholder manufacturer's specification. Because this tool is not center-cutting, feeds and speeds should be programmed for peripheral entry or ramp entry rather than direct plunge moves. Confirm cutting direction is set to right-hand rotation before engaging the spindle.
