3 5 and 6 Flute Corner Radius

3 5 and 6 Flute Corner Radius


High-performance carbide end mills with corner radii are the unsung heroes of precision machining. These versatile tools combine the benefits of standard carbide end mills with the added advantage of a rounded corner, offering a unique set of advantages that can transform your machining capabilities. 

Advantages of High-Performance End Mills with Corner Radius:

  • Improved Tool Life: The presence of a corner radius reduces stress concentrations at the corners of the cutting edge. This means that these end mills are less prone to chipping or breaking, resulting in a longer tool life compared to sharp-cornered counterparts. You'll spend less time changing tools and more time machining.

  • Enhanced Surface Finish: The rounded corner of these end mills produces a smoother finish on the workpiece. This is particularly valuable when working on materials like aluminum and plastics, where a sharp corner can leave marks or imperfections. With a corner radius end mill, you can achieve a pristine surface finish without the need for additional finishing operations.

  • Reduced Wear and Tear: Machining with sharp corners can lead to excessive wear on your end mills and the workpiece. High-performance corner radius end mills distribute cutting forces more evenly, reducing wear on both the tool and the material. This translates into cost savings through reduced tool replacement and material waste.

  • Versatile Machining: High-performance corner radius end mills are suitable for a wide range of applications. Whether you're contouring, slotting, profiling, or facing, these tools can handle it all. They are especially effective in 3D machining, where sharp corners may not be suitable due to tool engagement limitations.

  • Optimized Chip Evacuation: The corner radius design aids in chip evacuation, reducing the risk of chip buildup and tool overheating. This is especially crucial in high-speed machining operations, where efficient chip removal is essential for maintaining cutting performance.

  • Precise Radii Selection:  Atlas offers a variety of corner radius options, allowing you to choose the exact radius that suits your machining needs. This level of precision enables you to tailor your tool selection to specific project requirements.

Applications: High-performance carbide end mills with corner radii find applications across various industries, including aerospace, automotive, medical, mold and die, and general machining. They are ideal for tasks like:

  • Contouring complex 3D surfaces.
  • Reducing the risk of tool breakage in heavy cutting.
  • Achieving tight tolerances and fine finishes.
  • Minimizing material waste through optimized tool wear.

By Investing in Atlas high-performance carbide end mills with corner radii they can significantly elevate your machining capabilities.
