Accupro 12180351 Corner Rounding End Mill 1/8 in Radius

Product Description

The ACCUPRO 12180351 is a solid carbide corner rounding end mill designed to machine precise convex radii on workpiece edges. Built as a double-end tool, it delivers a 1/8 inch radius profile with a 5/16 inch mill diameter and a 0.0630 inch tip diameter. The 2-flute geometry supports efficient chip evacuation and clean edge formation on ferrous and non-ferrous materials. Right-hand cutting and right-hand flute direction make it compatible with standard CNC machining center setups. The bright, uncoated finish keeps the tool ready for use without additional prep. Machinists and CNC operators in job shops, tool rooms, and production environments rely on this geometry for consistent corner rounding passes.

The 12180351 is suited for edge-profiling operations on milled components where a controlled 1/8 inch radius is required. The 5/16 inch shank diameter fits standard collet chucks and end mill holders common to vertical machining centers and CNC mills. Its double-end configuration extends tool life by providing a second usable cutting end, making it a practical choice for production runs where tool changes add cost. The solid carbide construction handles the rigidity demands of light to moderate milling cuts in steel, aluminum, brass, and similar materials.

Key Features

• 1/8 inch corner radius for precise convex edge profiling
• Double-end design provides two cutting ends per tool
• Solid carbide construction for rigidity and wear resistance
• 2-flute geometry promotes chip clearance during profiling passes
• Right-hand cut and right-hand flute direction for standard spindle compatibility
• Bright, uncoated finish — no coating prep required before use

Compatibility

Designed as an OEM-style corner rounding end mill for use in standard collet chucks and end mill holders accepting a 5/16 inch shank diameter on CNC vertical machining centers and manual mills.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Secure the 5/16 inch shank in a properly sized collet or end mill holder and verify runout before commencing cuts. Ensure the spindle is fully stopped and the machine is powered down or in a safe mode before changing or inspecting the tool. Do not exceed the tool manufacturer's recommended depth of cut or feed rate for the workpiece material.
