Value Collection 723-6417 Corner Rounding End Mill

Product Description

The VALUE COLLECTION 723-6417 is a single-end corner rounding end mill designed to produce precise radiused edges on ferrous and non-ferrous workpieces. Built from M42 cobalt high-speed steel, this tool handles interrupted cuts and tougher alloys that standard HSS end mills struggle with. It carries a 3/32 inch corner radius and a 1/2 inch mill diameter across four right-hand flutes, making it a practical choice for edge-breaking, deburring, and profile work on milling machines and machining centers. The bright, uncoated finish suits applications where coating interaction with the workpiece material is a concern.

This end mill is suited for manual mills, CNC vertical machining centers, and knee mills performing corner rounding operations on steel, stainless, cast iron, and similar materials. The 3/8 inch shank diameter fits standard R8, collet chuck, and end mill holder setups common in job shops and maintenance machining environments. It is a single-end tool, so the working end is not reversible. Machinists and tool-and-die technicians are the primary installers of this cutter.

Key Features

• M42 cobalt construction for improved heat and wear resistance compared to standard M2 HSS
• 3/32 inch corner radius for consistent, repeatable edge rounding
• Four right-hand flutes with right-hand cutting direction for standard milling spindle rotation
• Bright, uncoated finish — no coating interaction with workpiece or coolant chemistry
• Single-end design with 3/8 inch shank for direct collet or end mill holder mounting

Compatibility

Designed as a standard single-end corner rounding end mill compatible with milling machines and machining centers that accept a 3/8 inch shank via collet chuck, R8 collet, or end mill holder.

Installation Notes

This cutter is installed by a machinist or toolroom technician. Power down and lock out the spindle before changing tooling per OSHA lockout/tagout procedures. Seat the 3/8 inch shank fully into the holder and torque the drawbar or set screw to the machine manufacturer's specification. Inspect the cutting edges for chips or cracks before each use and do not exceed the recommended speed and feed for the workpiece material and cutter diameter.
