New circle segment end mill

October 15, 2025

With advances in 5-axis machining and modern CAM systems, the demands placed on the machining of complex 3D surfaces are constantly increasing. Conventional ball nose or torical end mills often reach their limits here – especially with deep cavities, small radii, or areas that are difficult to access.

Our new circle segment end mill offers the perfect solution: Thanks to its innovative geometry with a large cutting radius, it is increasingly replacing classic end mill shapes and enables up to 90 % faster finishing.

Whether in tool and mold making, the aviation industry, or medical technology, the HPTec circle segment end mill increases efficiency, quality, and cost-effectiveness in equal measure. Your advantages at a glance:

• Accelerated machining: Larger line spacing between the paths significantly reduces machining time.
• Outstanding surface quality: Despite larger path distances, the surface remains consistently fine and precise.
• Increased productivity: Shorter finishing times mean that more components can be manufactured in the same amount of time.
• Longer service life: Uniform tool wear ensures a longer service life.
• Maximum versatility: Whether conical or tangential design – the right tool for every application.
