Accupro 12182969 Corner Radius End Mill 1 in 4 Flute Carbide

Product Description

The ACCUPRO 12182969 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining applications. It features a 1 inch cutting diameter, a 2-1/4 inch length of cut, and a 1/8 inch (0.1250 inch) corner radius that reduces stress concentrations and extends tool life in profiling and finishing passes. Built from micrograin carbide, this single-end, center-cutting tool runs right-hand with a spiral flute geometry and a 40-degree helix angle. It is sized for use in CNC machining centers and manual mills where a 1 inch shank is required.

This end mill is suited for peripheral and slot milling in ferrous and non-ferrous materials where a corner radius profile is specified. The bright uncoated finish makes it a practical choice for applications where coating interaction with the workpiece material is a concern, or where re-sharpening is anticipated. The long-length configuration and 5 inch overall length allow reach into deeper pockets and stepped features without requiring extended-reach toolholders.

Key Features

• 1 inch cutting diameter with 1/8 inch corner radius for reduced notch stress and improved surface finish
• Micrograin solid carbide construction for rigidity and wear resistance
• 4-flute, right-hand spiral geometry with 40-degree helix for efficient chip evacuation
• Center-cutting design allows direct plunge entry into workpiece
• Bright uncoated finish suitable for general-purpose milling and regrind applications
• Long-length configuration with 5 inch OAL provides extended reach for deep-pocket work

Compatibility

Designed as an OEM-style replacement or direct application tool for CNC machining centers and manual milling machines accepting a 1 inch straight shank in an ER, hydraulic, or shrink-fit toolholder.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the tool path is verified before engaging the workpiece. Secure the shank in a clean, properly sized toolholder to the full recommended engagement depth to minimize runout. Confirm spindle direction is set to right-hand rotation before initiating the cut.
