SK-5M AlTiN-Coated Double Cut 90° Countersink Burr for Vertical Countersinking and Chamfering


The SK-5M carbide rotary burr features a 90° countersink shape with a double‑cut design and an AlTiN (aluminum titanium nitride) coating, developed specifically for vertical countersinking, right‑angle chamfering, and hole‑edge finishing. The coating enhances surface hardness and heat resistance, reducing wear during continuous use and extending tool life.

The 90° taper accurately matches standard vertical countersink requirements, while the double‑cut structure improves cutting efficiency and helps achieve a smooth, clean chamfer surface. 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 right‑angle chamfering, weld groove preparation, and standard vertical countersink production, this is a durable coated rotary burr tool focused on precision and reliability.
