Accupro 12179325 Corner Rounding End Mill 1/4 in 2 Flute

Product Description

The ACCUPRO 12179325 is a double-end corner rounding end mill designed to produce consistent radius profiles on workpiece edges in precision machining applications. Built from solid carbide with a titanium nitride (TiN) coating, it delivers long tool life and resistance to heat buildup during high-speed cutting. The mill features a 0.094 inch radius, a 0.25 inch mill diameter, and a 0.062 inch tip diameter. With 2 right-hand flutes and right-hand cutting direction, it is suited for finish edge-profiling operations on ferrous and non-ferrous metals. Machinists and tool-and-die professionals install this tool in standard CNC machining centers and manual mills.

This corner rounding end mill is used in shop environments where repeatable edge-break geometry and tight radius tolerances are required. Typical applications include die work, mold machining, aerospace component finishing, and general precision part production. The double-end configuration extends usable tool life by providing two working ends on a single blank. The 0.25 inch shank diameter fits standard collets and toolholders commonly found in both CNC and conventional milling setups.

Key Features

• Solid carbide construction for rigidity and extended wear resistance
• TiN coating reduces friction and improves edge retention during cutting
• Double-end design provides two usable cutting ends per tool
• 0.094 inch radius for consistent corner profile geometry
• Right-hand cut and right-hand flute direction for standard spindle compatibility
• 0.062 inch tip diameter suited to tight-clearance profiling passes

Compatibility

Designed as an OEM-style replacement or direct-use corner rounding end mill for standard 1/4 inch collet toolholders used in CNC and manual milling machine setups.

Installation Notes

Installation should be performed by a qualified machinist familiar with end mill toolholding practices. Ensure the machine spindle is fully stopped and locked out before changing tooling. Secure the 0.25 inch shank in a clean, undamaged collet or toolholder to the appropriate clamping torque per the toolholder manufacturer specification. Inspect the cutting edges for chips or damage before use and do not exceed the recommended speed and feed parameters for the workpiece material.
