SL‑4M AlTiN‑Coated Ball Nosed Cone Aluminum Cut Carbide Burr - For Aluminum Curved and High‑Temp Work
The SL‑4M carbide rotary burr combines an AlTiN coating with an aluminum‑cut design and a ball nosed cone profile, optimized for curved‑surface machining, internal‑corner work, and high‑temperature environments on aluminum and aluminum alloys. The coating enhances surface hardness and heat resistance, reducing wear and material adhesion during cutting and extending tool life.

The ball nose allows smooth contact with complex curves and internal radii, while the tapered area is suitable for slope finishing and progressive material removal. The aluminum‑cut further reduces adhesion risks in soft‑metal processing. The tool performs reliably during continuous or high‑temperature operations, balancing efficiency with machining quality.
Compatible with standard electric and pneumatic equipment, it is easy to operate and maintain. Widely used in high‑temperature trimming of aluminum molds, curved‑surface finishing of components, weld‑transition processing, and heat‑resistant aluminum part machining, this is a practical rotary burr that integrates coating technology with soft‑metal machining features.
Caburtech offers a wide selection of carbide burr shapes in Single and Double Cut styles, including Cylinder, Round nose cylinder, Ball, Oval, Tree, Flame, Cone, Countersink and Inverted Cone. Each shape is designed for grinding, deburring, chamfering, and finishing on steels under 60 HRC, stainless steels, cast iron and etc.
