Value Collection 183-6163 Corner Rounding End Mill 1in 4FL Hss

Product Description

The VALUE COLLECTION 183-6163 is a single-end corner rounding end mill designed to produce consistent radius profiles on workpiece edges in milling operations. Built from M2 high speed steel and finished with a titanium nitride (TiN) coating, this tool delivers improved wear resistance and longer tool life compared to uncoated HSS. It features a 1 inch cutting diameter, a 1/4 inch corner radius, and a 1/2 inch shank diameter. The 4-flute, right-hand cut and right-hand helix geometry provides efficient chip evacuation and smooth surface finishes. Machinists and tool-and-die professionals rely on this geometry for edge-breaking and decorative radius work on ferrous and non-ferrous materials.

This end mill is suited for use on manual knee mills and CNC machining centers in job shop, production, and maintenance environments. It is appropriate for edge rounding operations on steel, aluminum, and similar machinable materials where a precise 1/4 inch radius is required. The single-end configuration and standard 1/2 inch shank fit conventional end mill holders, collet chucks, and Weldon-style tool holders common in most shops.

Key Features

• 1/4 inch corner radius for consistent, repeatable edge profiles
• M2 high speed steel construction for toughness across a range of materials
• Titanium nitride (TiN) coating improves surface hardness and reduces friction at the cutting edge
• 4-flute, right-hand cut geometry with right-hand helix for smooth chip flow
• 1/2 inch shank diameter fits standard end mill holders and collet chucks
• Single-end design for straightforward setup and tool changes

Compatibility

Designed as a standard-geometry corner rounding end mill suitable for use in any milling machine or machining center that accepts a 1/2 inch shank end mill holder or collet chuck.

Installation Notes

Installation should be performed by a qualified machinist. Ensure the spindle is fully powered down and locked out before loading or changing tools. Seat the shank fully in the holder to the minimum insertion depth recommended by the holder manufacturer, and torque set screws or collet nuts to the tool holder specification. Inspect the TiN coating and cutting edges for chips or wear before each use.
