Accupro 12182873 Corner Radius End Mill 3/8 in 4 Flute

Product Description

The ACCUPRO 12182873 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining environments. It features a 3/8-inch mill diameter with a 1/8-inch (0.1250-inch) corner radius that reduces stress concentrations at the cutting edge and extends tool life in demanding applications. The 4-flute, right-hand spiral configuration promotes efficient chip evacuation and a smooth surface finish. With a stub-length geometry and bright/uncoated finish, this single-end centercutting tool is suited for use on CNC machining centers and manual mills. It is typically installed by machinists and tooling technicians working in precision manufacturing, tool-and-die, or maintenance machining settings.

This end mill is applicable to a wide range of milling tasks including profile milling, slotting, and peripheral cutting where a radiused corner is required to reduce part stress or meet drawing callouts. The stub flute length and solid carbide micrograin construction make it particularly effective in harder workpiece materials where rigidity and edge retention are priorities. It is a single-end tool sold individually and is appropriate for both production and prototype machining work.

Key Features

• 3/8-inch mill diameter with 0.1250-inch corner radius for reduced edge stress and improved part geometry
• 4-flute right-hand spiral design promotes smooth cutting action and efficient chip removal
• Solid carbide micrograin construction provides rigidity and edge retention in harder materials
• Centercutting geometry allows plunge entry directly into the workpiece
• Bright/uncoated finish suitable for a wide range of general-purpose milling applications
• Stub flute length increases tool stiffness and reduces deflection in short-reach setups

Compatibility

Designed as a standard 3/8-inch shank corner radius end mill compatible with collet chucks, end mill holders, and tooling systems accepting a 3/8-inch straight shank diameter.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Ensure the spindle is fully stopped and the machine is powered down or in a safe lockout/tagout state before changing tooling. Seat the shank fully into the holder to the recommended gauge-line depth and torque the retention mechanism per the toolholder manufacturer's specification. Verify runout at the cutting edge after installation before beginning a cut.
