Value Collection 183-6643 Corner Rounding End Mill 4 Flute

Product Description

The VALUE COLLECTION 183-6643 is a single-end corner rounding end mill designed to produce precise radius profiles on workpiece edges. Built from M2 high speed steel and finished with a titanium nitride (TiN) coating, it delivers extended tool life in a range of ferrous and non-ferrous machining applications. The mill features a 1 inch radius, a 2.625 inch cutting diameter, and a 1 inch shank diameter, making it suited for heavy material removal on manual mills and CNC machining centers. Four right-hand flutes with a right-hand cutting direction provide efficient chip evacuation and a smooth finished edge contour. Machinists and toolroom operators working in job shops, production facilities, and maintenance environments rely on this geometry for consistent edge-break and radius work.

This corner rounding end mill is used in milling operations where a controlled radius must be applied to a part edge without secondary hand-finishing. It is appropriate for use in both manual vertical milling machines and CNC machining centers capable of accepting a 1 inch shank. Typical applications include tooling, fixtures, dies, and general fabricated components where a clean 1 inch radius profile is required. The TiN coating reduces friction and improves wear resistance, extending cutting intervals between tool changes in production runs.

Key Features

• 1 inch corner radius for consistent edge profiling in a single pass
• M2 high speed steel construction for toughness across a range of workpiece materials
• Titanium nitride coating reduces friction and extends tool life
• Four right-hand flutes with right-hand cutting direction for efficient chip removal
• Single-end configuration with a 1 inch shank diameter for secure, low-runout clamping
• 2.625 inch overall mill diameter accommodates wide radial engagement

Compatibility

Designed for use in milling machines and CNC machining centers with a collet, end mill holder, or toolholder sized for a 1 inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the machine spindle is fully de-energized and locked out before changing tooling. Seat the shank fully into a properly sized end mill holder or collet and torque the retention hardware to the toolholder manufacturer specification. Inspect the TiN coating and cutting edges for chips or wear before use; do not run a damaged tool.
