Value Collection 840-0140 Square End Mill 9/64 in Hss

Product Description

The VALUE COLLECTION 840-0140 is a double-end, square-profile end mill designed for general-purpose milling operations in machine shops and production environments. Built from high speed steel (HSS), this tool offers reliable performance on a wide range of ferrous and non-ferrous workpiece materials. It has a 9/64 inch (0.1406 inch) cutting diameter, a 13/32 inch (0.4063 inch) length of cut, and a 2-flute spiral configuration with a 30-degree helix angle. The bright, uncoated finish makes it straightforward to inspect for wear. At 0.02 pounds, it is a lightweight, small-diameter tool suited for fine detail work and tight-tolerance cuts.

This end mill is intended for use in CNC machining centers, manual knee mills, and drill-press-style milling setups where small-diameter, precise cuts are required. The double-end design allows the operator to flip the tool and use the second cutting end when the first shows wear, effectively doubling service life per tool. It is well suited for slotting, profiling, and light contouring operations in aluminum, mild steel, brass, and similar materials. Machinists, tool-and-die makers, and maintenance technicians working with small-scale or intricate part geometries are the primary users of this tool.

Key Features

• Double-end design provides two usable cutting ends per tool
• High speed steel construction for versatile cutting across common workpiece materials
• 30-degree helix angle promotes smooth chip evacuation during milling operations
• Center-cutting capable, allowing plunge entry into workpiece material
• Right-hand cut and right-hand flute direction for standard spindle setups
• Bright, uncoated finish for easy visual wear inspection

Compatibility

Designed as an OEM-style replacement or direct-use tooling for standard straight-shank collet systems accepting a 3/16 inch shank diameter. Part of the Series 840 regular-length end mill family.

Installation Notes

Installation and use should be performed by qualified machinists or trained tool operators. Before tool changes, the machine spindle must be fully de-energized and brought to a complete stop. The straight shank should be secured in a properly sized collet or end mill holder torqued to the machine manufacturer's specification. Inspect the cutting edges and shank for damage before each use, and never exceed the manufacturer's recommended speeds and feeds for the tool diameter and workpiece material.
