Value Collection 840-0109 Square End Mill 7/64 in Hss

Product Description

The VALUE COLLECTION 840-0109 is a double-end square end mill designed for precision milling operations in metal, plastic, and composite materials. Machined from high speed steel (HSS), it features a 7/64 inch (0.1094 inch) mill diameter with a 21/64 inch (0.3281 inch) length of cut and a 2-1/4 inch overall length. The double-end configuration delivers two usable cutting ends per tool, extending service life before replacement is required. With 2 flutes and a 30-degree helix angle, this end mill is suited for general-purpose slot milling, profiling, and light plunge cutting in manual mills and CNC machining centers. Installation and use are performed by machinists and tool-and-die professionals.

This end mill fits standard 3/16 inch straight shank toolholders and collet chucks commonly found in both manual knee mills and CNC machining centers. It is appropriate for light-to-medium duty material removal in job shop, production, and maintenance machining environments. The Series 840 regular-length geometry suits applications where a short, rigid setup is preferred over extended-reach configurations. Center-cutting capability allows direct plunging into workpiece material without pre-drilling.

Key Features

• Straight 3/16 inch shank fits standard collet chucks and end mill holders

Compatibility

Designed as a general-purpose replacement or stock end mill for any milling machine or machining center that accepts a 3/16 inch straight shank toolholder or collet. No specific model or series compatibility data was provided in the product documentation.

Installation Notes

Installation is performed by a qualified machinist. Ensure the machine spindle is fully powered down and locked out before inserting or removing the tool from the collet or end mill holder. Verify collet size matches the 3/16 inch shank diameter and torque the drawbar or collet nut per machine manufacturer specifications. Inspect both cutting ends for edge integrity before use and do not exceed the rated length of cut for this tool series.
