Accupro 12176799 Corner Radius End Mill 3/16 in 3 Flutes

Product Description

The ACCUPRO 12176799 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining applications. It features a 3/16 inch cutting diameter, a 0.03 inch corner radius, and three flutes with a right-hand cutting and flute direction. The 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. With a bright/uncoated finish, this end mill is suited for general-purpose use across a range of workpiece materials. It is centercutting, allowing plunge cuts in addition to peripheral and slot milling. Licensed machinists and CNC operators are the primary installers and users of this tooling.

This end mill is well suited for light to medium milling tasks in job shop, production machining, and toolroom environments. The 3/8 inch length of cut and 2 inch overall length make it appropriate for shallow-depth profiling, contouring, and slotting operations. The coarse pitch and regular length classification position it as a general-purpose option for both manual mills and CNC machining centers. The 3/16 inch shank diameter is compatible with standard collets and end mill holders of the same bore size.

Key Features

• 0.03 inch corner radius reduces stress concentration and improves edge durability on workpiece corners
• Three-flute geometry balances chip clearance and cutting stability for general-purpose milling
• Solid carbide construction provides hardness and rigidity for consistent dimensional accuracy
• 30-degree helix angle supports efficient chip evacuation and reduced cutting forces
• Centercutting design allows direct plunge entry into workpiece material
• Bright/uncoated finish suitable for use with or without cutting fluid across common workpiece materials

Compatibility

Designed as an OEM-style solid carbide corner radius end mill for use in standard 3/16 inch bore collets and end mill holders on manual milling machines and CNC machining centers.

Installation Notes

This tooling is installed and operated by qualified machinists familiar with CNC or manual milling equipment. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully in the collet or end mill holder and torque the retention hardware according to the tool holder manufacturer specifications. Verify runout with a dial indicator before beginning any production cuts.
