Value Collection 840-0062 Square End Mill 1/16 in Hss

Product Description

The VALUE COLLECTION 840-0062 is a double-end square end mill designed for precision milling operations in metal and general-purpose machining environments. Manufactured from high speed steel (HSS), it features a 1/16 inch (0.0625 inch) mill diameter and a 3/16 inch length of cut, making it well suited for fine slotting, profiling, and contouring work where small-diameter tooling is required. With a 30-degree helix angle and two spiral flutes, the tool promotes smooth chip evacuation and reduces cutting forces during light material removal. Machinists and toolroom technicians are the primary users of this size class.

This end mill is appropriate for light-duty milling on ferrous and non-ferrous materials in both manual and CNC machining setups. Its small diameter and regular-length geometry make it a common choice for detail work, engraving-adjacent profiling, and narrow slot cutting on bench mills, knee mills, and CNC machining centers. The double-end design extends usable tool life by providing two cutting ends per shank. It belongs to the Series 840 product line.

Key Features

• Double-end configuration provides two usable cutting ends per tool
• High speed steel construction suitable for a range of ferrous and non-ferrous workpiece materials
• 30-degree right-hand helix promotes efficient chip flow in shallow cuts
• Center-cutting capable, allowing plunge entry into the workpiece
• Bright/uncoated finish — no coating buildup to affect tolerances on small-diameter tooling
• Straight shank and regular length geometry for standard collet and end mill holder compatibility

Compatibility

Designed as an OEM-style replacement or standard-use small-diameter end mill compatible with 3/16 inch straight-shank collets and end mill holders on manual mills and CNC machining centers.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully powered down and locked out before changing tooling. Seat the shank fully into the collet or end mill holder and torque the retention nut to the tool holder specification before engaging the spindle. At this diameter, runout control is critical — verify tool runout with a dial indicator before beginning a cut to avoid premature tool breakage.
