Accupro 12183451 Corner Radius End Mill 3/16 in 4 Flute

Product Description

The ACCUPRO 12183451 is a solid carbide corner radius end mill designed for precision milling operations in metal cutting and machining applications. With a 3/16 inch diameter, a 1 inch length of cut, and a 0.01 inch corner radius, this tool delivers controlled edge geometry suited for profiling, slotting, and contouring on hardened and general-purpose workpieces. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. It ships in a bright/uncoated finish, making it suitable for applications where coating is not required or where the user applies their own surface treatment. Micrograin carbide construction provides wear resistance and edge retention under demanding cutting conditions.

This end mill is used in CNC machining centers, vertical mills, and manual knee mills across job shops, toolrooms, and production environments. The single-end, centercutting design allows plunge entry and is appropriate for ferrous and non-ferrous materials. The long-length configuration with a 4 inch overall length extends reach for deeper pockets or tiered setups. Machinists and toolroom operators working in aerospace, automotive, die/mold, and general metalworking applications are the primary users of this geometry.

Key Features

• 3/16 inch mill diameter with micrograin solid carbide construction for edge retention
• 0.01 inch corner radius reduces stress concentration at workpiece edges
• 40-degree helix angle for improved chip flow and surface finish
• Centercutting design allows direct plunge entry without pre-drilling
• Right-hand cut and right-hand flute spiral for standard CNC and manual mill setups
• Bright/uncoated finish compatible with a wide range of cutting fluids and coatings

Compatibility

Designed as an OEM-style replacement or standard tooling selection for CNC machining centers and manual mills accepting 3/16 inch shank toolholders, collets, or end mill holders.

Installation Notes

Installation should be performed by a qualified machinist following standard toolholding procedures. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the holder. Use a properly sized collet or end mill holder matching the 3/16 inch shank diameter to maintain runout tolerances within specification. Follow the tool manufacturer and machine OEM guidelines for feeds, speeds, and depth of cut for solid carbide tooling in the workpiece material being machined.
