Value Collection 842-0140 Square End Mill 9/64 in 2 Flute Hss

Product Description

The VALUE COLLECTION 842-0140 is a double-end, square-profile end mill designed for general-purpose milling operations in machine shop and manufacturing environments. Built from high speed steel (HSS) and left uncoated in a bright finish, this tool delivers reliable performance in ferrous and non-ferrous materials. It features a 9/64-inch (0.1406-inch) mill diameter, a 7/32-inch (0.2188-inch) length of cut, and a 3/16-inch (0.1875-inch) straight shank. With two flutes and a 30-degree right-hand helix, it is center-cutting and capable of plunge entry. Machinists and CNC operators use this stub-length tool where rigidity and compact reach are priorities.

This end mill suits light to medium milling tasks including slotting, profiling, and step milling in ferrous metals, aluminum, brass, and plastics. The stub length classification contributes to reduced deflection during cuts, making it a common choice on manual mills and CNC machining centers where close-tolerance work in small features is required. The double-end design extends tool life by providing two usable cutting ends before the tool is retired. It is sold individually and is a suitable fit for production shops, toolroom applications, and maintenance machining.

Key Features

• Double-end design provides two cutting ends, extending usable tool life
• Center-cutting geometry allows direct plunge into workpiece material
• 30-degree right-hand spiral flute promotes efficient chip evacuation
• Uncoated bright finish suits a wide range of general-purpose materials
• Stub length construction increases rigidity and reduces deflection
• Straight shank compatible with standard collet and end mill holders

Compatibility

Designed as a general-purpose replacement or stock end mill for use in standard 3/16-inch collets or end mill holders on manual knee mills, CNC machining centers, and similar machine tool setups. No specific OEM or system compatibility was stated by the manufacturer for this part.

Installation Notes

Installation is performed by a machinist or toolroom technician. Ensure the machine spindle is fully stopped and the power is locked out before changing tooling. Seat the straight shank fully into the collet or holder and torque the retention system according to the machine tool manufacturer's specifications. Inspect the cutting edges for chipping before each use and replace the tool if damage is observed.
