Accupro 12182756 Corner Radius End Mill 3/16in 4 Flute

Product Description

The ACCUPRO 12182756 is a solid carbide corner radius end mill designed for precision milling in metalworking and machining applications. It features a 3/16-inch diameter with a 0.015-inch corner radius that reduces stress concentration at the cutting edge and extends tool life in demanding cuts. The 4-flute, right-hand spiral geometry with a 40-degree helix angle promotes efficient chip evacuation and smooth surface finishes. At 2 inches overall length with a 3/8-inch length of cut, this stub-length tool offers rigidity in tight-tolerance work. The bright, uncoated finish suits general-purpose use across a range of ferrous and non-ferrous materials. Installed by machinists and CNC operators in production and job-shop environments.

This end mill is suited for slot milling, profiling, and contouring operations where a controlled corner radius is required to prevent sharp-corner stress risers. The centercutting design allows plunge entry, giving operators flexibility in toolpath programming. The stub-length configuration reduces deflection during aggressive side-milling passes. Typical applications include finishing passes on steel, aluminum, and similar materials where edge integrity and dimensional accuracy are critical.

Key Features

• 3/16-inch mill diameter with matching 3/16-inch shank for direct collet or end mill holder mounting
• 0.015-inch corner radius reduces edge chipping and stress at part corners
• 4-flute right-hand spiral with 40-degree helix for efficient chip removal and surface finish
• Centercutting geometry allows plunge milling without a pre-drilled pilot hole
• Micrograin solid carbide construction provides hardness and wear resistance
• Bright/uncoated finish suitable for a broad range of workpiece materials

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC machining centers and manual mills accepting 3/16-inch shank end mills via collet chuck or end mill holder.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the spindle is fully stopped and locked before inserting or removing the tool from the holder. Use a properly sized collet or end mill holder and torque the retention mechanism to the machine manufacturer specification. Inspect the cutting edges and shank for runout before beginning a production cycle.
