Value Collection 723-6465 Corner Rounding End Mill Cobalt

Product Description

The VALUE COLLECTION 723-6465 is a single-end corner rounding end mill designed to machine precise convex radii on workpiece edges and shoulders. Built from M42 cobalt high-speed steel, it offers increased heat and wear resistance compared to standard M2 HSS tooling, making it well suited for cutting harder steels, stainless alloys, and other tough materials. The tool measures 1 inch in diameter with a 1/4 inch corner radius and runs a 1/2 inch shank diameter. Four right-hand flutes with a right-hand cutting direction deliver smooth chip evacuation and a clean surface finish on each pass. The bright, uncoated finish is standard for general-purpose cobalt tooling.

This end mill is used in manual mills, CNC machining centers, and knee mills where edge-breaking and radius profiling are required. It is appropriate for job shops, tool rooms, and production environments handling ferrous and non-ferrous workpieces. Typical applications include rounding sharp corners on milled components, blending edges on fixture plates, and producing consistent radii on die and mold cavities. Licensed machinists and tool-and-die makers are the primary users of this cutter.

Key Features

• M42 cobalt HSS construction for improved hot hardness and wear resistance over standard M2 tooling
• 1/4 inch corner radius produces a consistent convex edge profile in a single pass
• 4-flute geometry balances chip clearance with surface finish quality
• Right-hand cut and right-hand flute direction suit standard spindle rotation on most mills
• 1/2 inch shank diameter fits common ER and end mill holders without adapters
• Bright, uncoated finish allows easy visual inspection of cutting edge condition

Compatibility

Designed as a direct-fit replacement-style corner rounding end mill for any milling machine or machining center that accepts a 1/2 inch shank end mill holder.

Installation Notes

A licensed machinist should install and operate this tool following standard milling safety practices. Secure the shank fully in a clean, undamaged end mill holder and confirm runout before taking a cut. Power down and lock out the spindle before changing or inspecting the cutter. Do not exceed the cutter diameter or material-grade limitations outlined in the machine tool manufacturer documentation.
