Accupro 12176892 Corner Radius End Mill 1/16 in 4 Flute

Product Description

The ACCUPRO 12176892 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining applications. With a 1/16 inch (0.0625 inch) mill diameter and a 0.005 inch corner radius, this tool produces accurate contoured profiles and reduces stress concentration at part corners. The 4-flute, right-hand spiral configuration provides efficient chip evacuation and a smooth surface finish. The bright/uncoated finish makes it well suited for non-ferrous metals and general-purpose milling where coating is not required. It is installed and operated by CNC machinists and toolroom professionals working with precision milling machines.

This end mill is used in light-duty profiling, slotting, and contouring passes where a small-diameter tool and tight corner radius tolerance are critical. The centercutting geometry allows plunge milling in addition to standard peripheral and slot milling. It is appropriate for use in residential toolrooms, job shops, and production machining environments handling small, detailed workpieces in aluminum, brass, plastics, and similar materials.

Key Features

• 0.005 inch corner radius with a tolerance of plus or minus 0.001 inch for consistent profile accuracy
• Solid micrograin carbide construction for rigidity and wear resistance at small diameters
• 4-flute right-hand spiral for smooth cutting and efficient chip removal
• Centercutting design allows plunge entry without a pre-drilled hole
• Bright/uncoated finish suited for non-ferrous and general-purpose materials
• Single-end configuration with a 1/8 inch shank for compatibility with standard collet toolholders

Compatibility

Designed for use in standard milling machines and CNC machining centers that accept a 1/8 inch shank diameter. Confirm spindle collet or toolholder bore matches the 1/8 inch shank before installation.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines. Power down and lock out the spindle before inserting or removing the end mill from the collet or toolholder. Ensure the shank is fully seated and the collet is torqued to the toolholder specification before operation. Do not exceed the rated depth of cut for this diameter, as small-diameter carbide tools are susceptible to deflection and breakage under excessive load.
