Accupro 12182463 Corner Radius End Mill 1/4 in 4 Flute

Product Description

The ACCUPRO 12182463 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining applications. It features a 1/4 inch cutting diameter, a 0.03 inch corner radius, and a 4-flute spiral configuration with a 40-degree helix angle. The TiCN coating increases surface hardness and reduces friction, extending tool life in demanding cuts. At 2.5 inches overall length with a 3/4 inch length of cut, this single-end, centercutting tool handles both plunge and peripheral milling. Micrograin carbide substrate provides the rigidity needed for tight-tolerance work.

This end mill is suited for machining ferrous and non-ferrous metals in CNC milling centers and manual mills. The corner radius geometry reduces stress concentration at the cutting edge, making it a practical choice for finishing passes, profiling, and slotting where sharp inside corners are not required. The right-hand flute direction and right-hand cutting orientation are standard for conventional vertical and horizontal milling setups. Typical users include CNC machinists and tool-and-die professionals working in job shop and production environments.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• TiCN coating reduces friction and extends tool life in steel and alloy cuts
• 0.03 inch corner radius reduces edge chipping and stress at the cutting corner
• 40-degree helix angle promotes smooth chip evacuation
• Centercutting design allows direct plunge entry into workpiece
• Single-end configuration with right-hand cut and right-hand flute spiral

Compatibility

Designed as a standard 1/4 inch shank corner radius end mill compatible with CNC machining centers, vertical mills, and any spindle or collet system accepting a 1/4 inch straight shank.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and machine power is off before inserting or removing the tool from the collet or tool holder. Verify collet size matches the 1/4 inch shank diameter and that the tool is seated to the correct gauge length before tightening. Inspect the cutting edges for chips or damage prior to each use.
