3 Flutes Corner Rounding Endmills High Durability Standard End Mill Radius

Product Description:

Corner Radius End Mills , which are also commonly referred to as bull nose end mills , are cutting tools with a small radius at the corners rather than a sharp 90° edge. This curved corner design enhances the durability of the tool and helps prevent early chipping, especially when working with tougher materials.

These end mills are particularly well-suited for applications that demand robustness at the tool edge, enhanced surface finish, and extended tool lifespan. They are frequently utilized in tasks such as contouring, profiling, as well as mold and die making.

Special blade design, combined with advanced polishing
passivation technology, effectively prevent vibration and solve the problem of sticking chips;
High-performance aluminum knife can achieve ultra-high metal removal rate and higher requirements for appearance effects.

Features:

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.
