The BAER Countersink 90° Set is a six-piece conical countersink kit designed for stainless steel and high-strength metals. It delivers burr-free deburring and precise countersinking for clean, flat hole finishes, helping fasteners seat properly and edges stay safe to handle.

The set covers six sizes from 6.3 mm up to 20.5 mm (6.3 mm, 8.3 mm, 10.4 mm, 12.4 mm, 16.5 mm, 20.5 mm), including M3 to M10 equivalents, making it a versatile choice for workshops, maintenance, and fabrication tasks involving stainless steels such as V2A, V4A, INOX and other high-strength alloys.

• Six sizes in one compact set: Includes 6.3 mm, 8.3 mm, 10.4 mm, 12.4 mm, 16.5 mm, and 20.5 mm countersinks to deburr and countersink without tool changes, covering common hole sizes from M3 to M10.
• 90° countersink geometry with durable steel construction: Optimized for stainless steels and high-strength alloys, providing clean bevels and reliable performance for general-use applications.
• Burr- and chatter-free countersinking at low speeds: Designed for low cutting speeds to minimize chatter and produce smooth finishes, reducing rework and downtime.

Using this set helps you achieve professional-looking holes with minimal effort. The six sizes in one case streamline your workflow, reduce tool changes, and improve the seating surface quality for fasteners on stainless steel components. Built for durable performance in everyday projects, it supports consistent results across a range of tasks—from maintenance to precision fabrication—making it a dependable addition to any toolbox.
