Value Collection 723-5743 Roughing End Mill Cobalt M42

Product Description

The VALUE COLLECTION 723-5743 is a single-end cobalt roughing end mill designed for aggressive material removal in milling operations. Built from M42 cobalt high-speed steel, this end mill delivers the heat and wear resistance required for cutting harder ferrous and non-ferrous materials. The 4-flute, right-hand cutting geometry with a bright uncoated finish makes it well suited for roughing passes where chip clearance and edge strength are the primary concerns. The 0.625-inch diameter with a matching 0.625-inch shank provides consistent rigidity throughout the cut. It is installed and operated by machinists and tool-and-die professionals in shop environments.

This roughing end mill is used in vertical and horizontal milling machines for roughing operations on steel, stainless, cast iron, and similar materials. The 1.25-inch length of cut accommodates standard depth-of-cut requirements in most roughing applications. The single-end configuration focuses tool mass at the cutting end, which supports stability during high-material-removal-rate passes. It is a practical choice for production shops and job shops running manual or CNC milling equipment where a reliable, uncoated cobalt rougher is needed.

Key Features

• M42 cobalt high-speed steel construction for improved heat resistance over standard HSS
• 4-flute right-hand cutting geometry optimized for roughing passes
• Bright uncoated finish suitable for use with cutting fluid or dry applications
• Single-end design with 0.625-inch shank diameter matching the cutter diameter
• 1.25-inch length of cut with 3.375-inch overall length for standard milling setups
• Non-centercutting — requires a pre-drilled or pre-bored entry point

Compatibility

Designed as an OEM-style replacement or standard tooling option for milling machines accepting a 0.625-inch straight shank end mill.

Installation Notes

This end mill is installed by machinists using a compatible end mill holder, collet chuck, or side-lock holder sized for a 0.625-inch shank. Ensure the spindle and workpiece are fully secured and the machine is powered off before changing tooling. This is a non-centercutting tool and must not be plunged directly into solid material. Always verify runout after tool installation to maximize tool life and surface finish quality.
