Accupro 12180335 Corner Rounding End Mill 1/4 in 2 Flute

Product Description

The ACCUPRO 12180335 is a double-end corner rounding end mill designed to produce consistent radius profiles on workpiece edges. Built from solid carbide with an AlTiN (aluminum titanium nitride) coating, it delivers strong wear resistance and thermal stability during high-speed milling operations. The 0.078-inch corner radius and 0.094-inch tip diameter make it well-suited for precise edge-breaking and radius forming on ferrous and non-ferrous materials. With a 1/4-inch mill diameter and 1/4-inch shank, the tool fits standard collet systems and is installed by machinists and tool-and-die professionals in CNC and manual milling setups.

This end mill is intended for use in precision machining environments including job shops, production milling, and tool room work. It performs corner rounding passes on steel, aluminum, stainless, and similar materials. The double-end configuration extends tool life by providing two usable cutting ends before the tool is retired. Right-hand cutting and right-hand flute direction match conventional milling setups on standard vertical and horizontal machining centers.

Key Features

• Solid carbide construction for rigidity and extended tool life in demanding cuts
• AlTiN coating provides high-temperature resistance and reduced friction at the cutting edge
• Double-end design delivers two cutting ends per tool, reducing per-edge cost
• 0.078-inch radius produces a consistent, repeatable corner profile
• Right-hand cut and right-hand flute direction for standard CNC and manual mill compatibility
• 1/4-inch shank diameter fits common collet and end mill holder systems

Compatibility

Designed as an OEM-style replacement and standard replacement for corner rounding operations on CNC machining centers and manual mills accepting a 1/4-inch shank end mill.

Installation Notes

Installation is performed by machinists or tooling technicians. Secure the shank fully in a clean, properly sized collet or end mill holder and torque to the machine tool manufacturer's specification before beginning any cut. Inspect both cutting ends for chips or coating damage before use. Follow all shop safety protocols and machine guarding requirements when changing or setting cutting tools.
