SD-5ZML6 DC Ball Shape Long Shank Carbide Burr for Deep Cavity Work

The SD-5ZML6 DC carbide rotary burr features a spherical head design, paired with a 150mm extended shank and a double‑cut structure (other tooth profiles customizable). It is suitable for deep‑hole, internal‑cavity, and curved‑surface machining tasks that are difficult to reach with standard tools. The long shank offers improved reach and flexibility, enabling cutting operations in confined spaces.

The spherical head adapts to multi‑angle curved surfaces, making it well‑suited for contour finishing, internal radius work, and surface smoothing. The double‑cut pattern balances cutting efficiency and surface quality, allowing for deburring, chamfering, and general surface processing on common metal materials such as steel and aluminum alloys.

Compatible with standard electric and pneumatic equipment, it operates reliably and is easy to maintain. This tool is widely used in mold‑cavity finishing, pipe‑weld seam cleaning, deep internal mechanical structure processing, and special curved‑surface workpiece machining. It is a practical long‑shank rotary burr that combines extended reach with excellent curved‑surface 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.
