Description

SN-4M AlTiN Coated Double Cut Carbide Burr - Heat and Wear Resistant Inverted Cone Design

The SN-4M carbide rotary burr features an inverted cone shape with a double‑cut design and an AlTiN (aluminum titanium nitride) coating, suitable for internal hole work, reverse‑slope finishing, and concave contour machining. The coating enhances surface hardness and heat resistance, reducing wear during continuous use and extending tool life.

The inverted cone profile enables 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 balances material removal efficiency with surface smoothness. The AlTiN coating performs reliably under moderate cutting conditions, helping maintain cutting sharpness and processing consistency.

Compatible with standard 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 durable and practical coated rotary burr tool.

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.
