Aluminum Radius Milling Tool Customized 45 Degrees Helix Angle

Corner Radius End Mills , also known as bull nose end mills , are cutting tools that differ from traditional end mills by having a small radius at the corners instead of a sharp 90° edge. This unique design with rounded corners enhances the durability of the tool and helps prevent premature chipping, particularly when working with tougher materials. These end mills are highly suitable for applications that demand robustness at the tool edge, enhanced surface finish, and extended tool lifespan.

They are widely utilized in various industries, such as contouring, profiling, and mold and die making, where precision and reliability are essential. Their distinct curved shape allows for smoother cutting operations and better performance in demanding machining tasks. Overall, corner radius end mills are versatile and efficient tools that can significantly improve machining outcomes.

Advantages of Corner Radius End Mills

Increased Tool Strength
The rounded corners reduce stress concentration, minimizing the risk of breakage and improving tool rigidity.

Improved Surface Finish
The smooth radius at the corners creates cleaner cuts and better surface quality, especially in finishing operations.

Reduced Chipping and Wear
Corner radii help prevent edge chipping, especially when cutting harder or abrasive materials.

Longer Tool Life
With less wear and breakage, these tools last longer, reducing tool replacement frequency and machine downtime.

Higher Feed Rates
The added edge strength allows for more aggressive cutting parameters, increasing productivity.

Ideal for 3D Contouring and Mold Making
Perfect for applications that require strong edges and smooth transitions, such as mold cavities, dies, and complex profiles.
