Value Collection 723-3725 Ball End Mill 3/8in 4 Flute Cobalt

Product Description

The VALUE COLLECTION 723-3725 is a single-end ball end mill designed for milling contoured surfaces, slots, and pockets in metalworking applications. Manufactured from M42 cobalt high-speed steel, this tool delivers strong heat and wear resistance compared to standard HSS tooling, making it well suited for harder workpiece materials. It features a 3/8 inch diameter, a 3/4 inch length of cut, and a 2-1/2 inch overall length. The bright uncoated finish is paired with four right-hand spiral flutes that promote efficient chip evacuation. This end mill is used by machinists and tool-and-die professionals in CNC and manual milling operations.

This ball end mill is appropriate for milling operations requiring a full-radius cutting profile, including 3D contouring, ramp milling, and finishing passes on ferrous and non-ferrous metals. The 3/8 inch shank diameter fits standard R8, ER, and set-screw style collet holders common in vertical milling machines and machining centers. The single-end configuration means full tool replacement when the cutting end reaches wear limits, which is standard practice for tooling in this class.

Key Features

• M42 cobalt construction provides increased red hardness and wear resistance over standard M2 HSS
• 4-flute spiral design improves surface finish and supports higher feed rates on ferrous materials
• Ball end geometry enables 3D contouring, profiling, and full-radius slot milling
• Right-hand cut and right-hand flute direction for standard spindle rotation
• Bright uncoated finish compatible with a wide range of cutting fluids and lubricants
• Single-end design with 3/8 inch shank for direct collet or end mill holder mounting

Compatibility

Designed as an OEM-style replacement or standard tooling selection for vertical milling machines and CNC machining centers accepting a 3/8 inch shank end mill holder or collet.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully powered down and locked before changing tooling. Secure the shank to the minimum recommended insertion depth in the collet or holder to prevent tool pullout under cutting loads. Verify runout with an indicator before beginning a cut, particularly for finish contouring operations.
