Accupro 12180343 Corner Rounding End Mill 1/4 in Carbide Ticn

Product Description

The ACCUPRO 12180343 is a double-end corner rounding end mill designed for machining precise radii on workpiece edges and contours. Built from solid carbide with a titanium carbonitride (TiCN) coating, it delivers hardness and wear resistance across a range of ferrous and non-ferrous materials. The mill features a 0.1 inch corner radius, a 0.25 inch mill diameter, and a tip diameter of 0.05 inches. With two right-hand flutes and right-hand cutting direction, it is suited for finish passes and edge-breaking operations on machining centers and manual mills. Machinists and tool-and-die professionals are the primary installers and users of this tool.

This end mill is used in precision machining environments including job shops, production facilities, and toolroom operations. It applies to milling operations where a controlled corner radius is required on steel, aluminum, stainless, and similar materials. The double-end design extends tool life by providing two usable cutting ends. The 0.25 inch shank diameter is compatible with standard collet systems and end mill holders common to CNC machining centers and manual knee mills.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding cuts
• TiCN coating increases surface hardness and reduces built-up edge on the cutting surfaces
• Double-end design provides two usable cutting ends, extending tool service life
• 0.1 inch corner radius for consistent, repeatable edge rounding
• Right-hand cut and right-hand flute geometry for standard spindle rotation
• 0.25 inch shank diameter fits standard collet and end mill holder systems

Compatibility

Designed as an OEM-style replacement or standard toolroom end mill for use in any machine tool accepting a 0.25 inch shank diameter via collet, end mill holder, or equivalent workholding.

Installation Notes

Installation should be performed by a qualified machinist following standard tool-holding practices. Ensure the machine spindle is fully stopped and the tool holder is clean and free of chips before seating the shank. Confirm runout with a dial indicator after tightening to minimize deflection and premature tool wear. Follow the tool and machine manufacturer guidelines for appropriate speeds, feeds, and depth of cut for the workpiece material.
