SN-4M Inverted Cone Shape Double Cut Carbide Burr - For Internal Reaming and Reverse Slope Machining
The SN-4M carbide rotary burr features a double‑cut (DC) design and an inverted cone shape, making it suitable for internal hole flaring, reverse‑slope finishing, and concave contour machining. The inverted cone profile facilitates progressive cutting from the inside outward, allowing access to inner edges and chamfer areas that are difficult to reach with standard tools.

The double‑cut structure maintains efficient material removal while helping to achieve a smooth machined surface. It is suitable for internal hole finishing, chamfering, and deburring on materials such as stainless steel, aluminum alloys, and tool steel. Made from wear‑resistant carbide, the tool performs consistently during continuous precision work.
Compatible with common electric and pneumatic tools, it is easy to operate and maintain. Widely used in mold‑cavity chamfering, pipe‑end finishing, inner‑edge machining of mechanical components, and special concave‑profile workpiece processing, this is a uniquely shaped and practical inverted‑cone rotary burr.
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.
