SE-3ZML6 DC Oval Long Shank Rotary Burr - 150mm Shank for Deep Cavity and Concave Work

The SE-3ZML6 DC6 carbide rotary burr combines a double‑cut design with an oval profile and a 150mm extended shank. It is suitable for deep‑cavity, concave‑area, and other hard‑to‑reach complex machining tasks. The long shank expands the working range, enabling stable and controlled cutting in deep holes, narrow channels, and recessed structures.

The oval profile allows smooth contact with multi‑direction curved surfaces, adapting well to concave contours and gradual surface transitions. The double‑cut structure balances cutting efficiency with surface smoothness. This tool is suitable for deep‑cavity finishing, internal‑edge deburring, and inner‑surface precision work on materials such as stainless steel, tool steel, and aluminum alloys.

Compatible with common electric and pneumatic equipment, it is easy to operate and maintain. Widely used for deep‑cavity mold processing, pipe‑inner‑wall shaping, internal mechanical‑structure refinement, and special concave‑profile workpiece machining, this is a practical rotary burr that combines extended reach with contour adaptability.

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.
