Value Collection 723-3786 Ball End Mill 1-1/4 in 6 Flute Cobalt

Product Description

The VALUE COLLECTION 723-3786 is a single-end ball end mill designed for milling contoured surfaces, slots, and complex three-dimensional profiles in metalworking applications. Manufactured from M42 cobalt high-speed steel, this tool offers strong heat and wear resistance suitable for cutting harder ferrous materials. It features a 1.25-inch cutting diameter, a 2-inch length of cut, and six spiral flutes arranged in a right-hand cutting and right-hand flute direction. The bright, uncoated finish leaves the base cobalt material exposed, making it easy to inspect for wear. This tool is sold individually and intended for use by machinists and tooling professionals operating manual or CNC milling equipment.

This ball end mill is suited for general metalworking operations including profiling, contouring, and finishing passes on steel, stainless steel, and other materials compatible with cobalt tooling. The 1.25-inch shank diameter matches the cutting diameter, providing a rigid straight-shank configuration that fits standard milling machine collets and end mill holders of the same bore size. It is appropriate for both manual knee mills and CNC machining centers in job shop, production, and tool-and-die environments.

Key Features

• M42 cobalt construction provides elevated heat resistance compared to standard M2 high-speed steel
• 6-flute spiral design increases feed rate capability and produces a smoother finish on profiling cuts
• Right-hand cut and right-hand flute direction — standard orientation for conventional milling setups
• Bright/uncoated finish allows visual wear inspection without coating interference
• Single-end configuration with a 4.5-inch overall length and matching 1.25-inch shank diameter for rigid tool holding
• No extended reach or variable helix — straightforward geometry for standard milling operations

Compatibility

Designed as a direct-fit replacement or standard tooling option for milling machines and machining centers accepting a 1.25-inch straight shank end mill holder or collet chuck.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines for tool holding and runout tolerances. Ensure the spindle is fully stopped and the machine is powered down before inserting or removing the end mill. Use a properly sized end mill holder or collet with the correct bore to match the 1.25-inch shank and torque the retention fastener according to the holder manufacturer specification. Inspect the cutting edges and shank for damage before each use.
