SJ-5M AlTiN-Coated Double Cut 60° Countersink Burr for Countersinking and Chamfering
The SJ-5M carbide rotary burr features a 90° countersink shape with a double‑cut design and an AlTiN (aluminum titanium nitride) coating, developed specifically for countersink chamfering, hole‑edge finishing, and tapered hole enlargement. The coating enhances surface hardness and heat resistance, reducing wear during continuous use and extending tool life.

The countersink taper accurately matches standard countersink angles, while 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. Made from wear‑resistant carbide, the tool delivers stable cutting performance during continuous operation.
Compatible with standard electric and pneumatic tools, it is easy to operate and maintain. Widely used in machining assembly holes, mold chamfering, weld groove preparation, and standard countersink production, this is a durable coated rotary burr tool focused on precision and reliability.
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.
