Value Collection 842-0078 Square End Mill 2 Flute Hss

Product Description

The VALUE COLLECTION 842-0078 is a double-end, square-profile end mill ground from high speed steel (HSS) for general-purpose milling on manual and CNC machine tools. With a 5/64-inch (0.0781-inch) cutting diameter and a 1/8-inch length of cut, this tool is built for small-feature milling work including slots, pockets, and profiling passes. The 3/16-inch straight shank fits standard collets and end mill holders. Two right-hand spiral flutes with a 30-degree helix angle promote chip evacuation and surface finish in a wide range of ferrous and non-ferrous materials. The bright, uncoated finish is suitable for general cutting without coolant-through requirements.

This end mill is suited for light-duty machining in job shop, tool room, and production environments where small-diameter cutting tools are required. The stub-length geometry provides added rigidity relative to longer reach configurations, making it a practical choice for shallow slot and contour work in steel, aluminum, brass, and plastics. The double-end design provides a second usable cutting end, extending tool life between replacements. Installation and use are appropriate for machining professionals operating knee mills, CNC machining centers, and similar equipment.

Key Features

• 5/64-inch (0.0781-inch) cutting diameter for small-feature milling work
• Double-end design provides two cutting ends per tool
• 2-flute right-hand spiral configuration with 30-degree helix angle for efficient chip evacuation
• High speed steel construction suitable for ferrous and non-ferrous materials
• Center-cutting capability allows plunge entry into workpiece
• Bright, uncoated finish — no coating concerns for regrinding or reuse
• Stub-length geometry adds rigidity for shallow-depth cuts

Compatibility

Designed for use in standard 3/16-inch collets or end mill holders on manual mills and CNC machining centers. Part of the Series 842 stub-length double-end end mill family.

Installation Notes

Installation should be performed by a qualified machinist or tooling professional. Power down and lock out the spindle before changing tooling. Seat the shank fully in the collet or holder and torque the retention nut per the machine manufacturer's specification. Verify runout with a dial indicator before beginning cuts, especially at small diameters where runout has a proportionally large effect on tool life and finish quality.
