Value Collection 183-6189 Corner Rounding End Mill

Product Description

The VALUE COLLECTION 183-6189 is a single-end corner rounding end mill designed to produce smooth, consistent radius profiles on ferrous and non-ferrous workpieces. Built from M2 high speed steel and finished with a titanium nitride (TiN) coating, it delivers improved wear resistance and extended tool life compared to uncoated HSS tooling. The mill measures 1-1/8 inches in diameter with a 9/32 inch corner radius and features 4 flutes for efficient chip evacuation. The 1/2 inch shank diameter provides secure seating in standard milling chucks and collets. It is suited for manual mills, CNC machining centers, and knee mills used in job shops and production environments.

This corner rounding end mill is used by machinists and toolmakers to break sharp edges and add precise radius profiles to part edges, slots, and shoulders. The right-hand cutting and right-hand flute direction make it compatible with conventional milling machine spindle rotation. Single-end configuration keeps the tool compact and straightforward to set. Typical applications include edge preparation on steel, aluminum, and alloy components in precision manufacturing, prototype work, and general machine shop operations.

Key Features

• M2 high speed steel construction for toughness in interrupted cuts and general milling
• Titanium nitride (TiN) coating reduces friction and improves tool longevity
• 9/32 inch corner radius for consistent edge profiling
• 4 flutes provide balanced chip clearance and surface finish quality
• Right-hand cut and right-hand flute direction for standard spindle use
• 1/2 inch shank diameter fits common milling chucks and ER collet systems

Compatibility

Designed as a single-end corner rounding end mill with a 1/2 inch shank, compatible with standard milling machine chucks, ER collet holders, and end mill holders accepting 1/2 inch shanks.

Installation Notes

Installation should be performed by a qualified machinist with the machine spindle fully powered down and locked out before tooling changes. Ensure the shank is fully seated and the collet or chuck is torqued to the machine manufacturer's specification before running. Inspect the TiN coating and cutting edges for chips or wear before each use. Do not exceed the recommended speeds and feeds for M2 HSS tooling in the material being cut.
