Value Collection 183-6668 Corner Rounding End Mill

Product Description

The VALUE COLLECTION 183-6668 is a single-end corner rounding end mill designed to machine precise convex radius profiles on workpiece edges. Built from M2 high speed steel and finished with a titanium nitride (TiN) coating, it delivers improved wear resistance and tool life compared to uncoated HSS tooling. The cutter measures 0.625 inches in diameter with a 1/8-inch corner radius and features four right-hand flutes with right-hand cutting direction. Overall length is 3 inches. Machinists and tool-and-die professionals use this end mill on manual mills and CNC machining centers for edge-rounding and radius-blending operations.

This corner rounding end mill suits general-purpose metalworking applications in job shops, tool rooms, and production machining environments. The 3/8-inch shank diameter fits standard collets and end mill holders found on vertical milling machines and machining centers. It is well suited for rounding sharp edges on steel, aluminum, and other machinable metals where a consistent 1/8-inch radius is required. The single-end configuration means the working geometry is on one end only.

Key Features

• 1/8-inch corner radius produces a consistent convex edge profile in a single pass
• M2 high speed steel construction provides toughness across a range of workpiece materials
• Titanium nitride coating increases surface hardness and reduces friction for extended tool life
• 4-flute, right-hand cut and right-hand spiral geometry for smooth chip evacuation
• 3/8-inch shank diameter fits standard collets and end mill holders
• Single-end design with 3-inch overall length for rigid reach in typical setups

Compatibility

Designed as an OEM-style replacement or standard corner rounding end mill for use in any vertical milling machine or CNC machining center accepting a 3/8-inch shank tool holder.

Installation Notes

Installation should be performed by a qualified machinist following standard tooling change procedures. Ensure the spindle is fully stopped and the machine is in a safe, de-energized state before changing tooling. Seat the shank fully into the collet or end mill holder and torque the drawbar or collet nut per the machine manufacturer guidelines. Verify runout with a dial indicator before beginning a cut to protect both the tool and the workpiece.
