Value Collection 841-0078 Ball End Mill 2 Flute Hss

Product Description

The VALUE COLLECTION 841-0078 is a double-end ball end mill designed for precision milling operations in ferrous and non-ferrous materials. Built from high speed steel (HSS), it delivers reliable cutting performance in a small-diameter format with a 0.0781-inch (5/64-inch) cutting diameter and a 0.2344-inch (15/64-inch) length of cut. The double-end configuration provides two usable cutting ends, extending tool life and reducing changeover frequency. With a right-hand cutting and right-hand flute direction, this 2-flute end mill suits standard CNC and manual milling applications where fine detail work and tight tolerances are required.

This end mill is suited for light-duty profiling, slotting, and contouring in small-part machining environments. The compact 0.0781-inch diameter makes it appropriate for engraving, die and mold work, and intricate 3D surface finishing passes. A 3/16-inch shank diameter allows it to seat in standard collets and end mill holders found on vertical machining centers, CNC routers, and manual knee mills. The 2-1/4-inch overall length provides adequate reach for most shallow-pocket applications without sacrificing rigidity at this diameter.

Key Features

• Double-end design provides two cutting ends per tool for extended service life
• High speed steel construction handles a broad range of workpiece materials
• 0.0781-inch (5/64-inch) cutting diameter suits fine-detail and small-part work
• 2-flute geometry promotes chip evacuation in slotting and profiling cuts
• Right-hand cut and right-hand flute direction compatible with standard spindle rotation
• Regular length profile maintains stiffness at small diameter

Compatibility

Designed as a standard replacement or stock end mill for use in any machine tool accepting a 3/16-inch shank; confirm collet or holder bore size before installation.

Installation Notes

Installation should be performed by a qualified machinist or toolroom professional. Power down and lock out the machine spindle before inserting or removing end mills. Seat the shank fully into the collet or end mill holder to the recommended engagement depth and torque the drawbar or set screw according to the machine tool manufacturer specifications. Inspect the cutting edges for chips or wear before each use, particularly at this small diameter where edge integrity directly affects surface finish and tool deflection.
