Value Collection 843-0156 Ball End Mill 0.1563 in 2 Flute Hss

Product Description

The VALUE COLLECTION 843-0156 is a double-end, 2-flute ball end mill designed for precision milling operations in metal, composites, and other machinable materials. Built from high speed steel, it offers reliable performance in contouring, slotting, and profiling applications where a radius cutting profile is required. The mill diameter is 0.1563 inches with a length of cut of 0.2344 inches and a stub-length overall length of 2 inches. The right-hand cutting and right-hand flute direction make it compatible with standard CNC and manual milling setups. Its double-end design provides an additional usable cutting end, extending tool life between replacements.

This end mill is suited for light-duty milling work in job shop, toolroom, and production environments. It is commonly used in CNC machining centers and manual knee mills for small-radius profiling and 3D contour work. The stub length classification keeps the tool rigid during cuts, which is especially useful when minimizing deflection in small-diameter applications. Machinists and toolroom operators working on dies, molds, and precision parts will find this tool appropriate for fine detail work at this diameter range.

Key Features

• Double-end design provides two usable cutting ends per tool
• High speed steel construction handles a wide range of machinable materials
• 0.1563 inch mill diameter suited for small-radius and detail milling
• Stub length classification improves rigidity and reduces deflection
• Right-hand cut and right-hand flute direction for standard spindle compatibility
• 2-flute geometry supports chip evacuation in slotting and profiling cuts

Compatibility

Designed as a replacement or stock end mill for CNC machining centers and manual milling machines accepting a 3/16 inch shank diameter collet or end mill holder.

Installation Notes

Installation should be performed by a qualified machinist following standard toolholding procedures. Secure the shank firmly in a collet or end mill holder rated for the 3/16 inch shank diameter before beginning any operation. Inspect the cutting edges for damage before mounting, and never exceed the tool manufacturer's recommended speeds and feeds for the workpiece material. Ensure the spindle is fully stopped and the machine is powered down before changing or adjusting the tool.
