Long Shank Carbide Burr SL-4ML6 DC Tree Shape Double Cut For Deep Cavity Work

SL-4ML6 DC Long Shank Ball Nose Tree Rotary Burr - 150mm Shank Double Cut for Deep Cavity Work

The SL-5ML6 DC carbide rotary burr features a double-cut design (other tooth profiles available) combined with a ball nose tapered shape and a 150mm extended shank. It is particularly suitable for machining deep cavities, extended‑reach areas, or spaces difficult to access with standard tools. The long shank maintains stable operation while extending reach and processing flexibility.

The ball nose section allows smooth handling of curved transitions and internal radii, while the tapered profile is suitable for slope finishing and progressive cutting. The double‑cut pattern balances material removal efficiency with surface smoothness, making it effective for deburring, chamfering, and finishing on common metals such as steel, aluminum, and cast iron.

Compatible with common electric and pneumatic equipment, it is straightforward to operate and maintain. This tool is widely used for deep cavity mold work, pipe interior finishing, internal mechanical structure processing, and cleaning weld seams in confined spaces. It is a long‑shank rotary burr that combines extended reach with practical functionality.

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.
