The BAER HSSG 90° Countersink is a precision tool designed to deburr holes and create accurate tapered offsets in metalwork. Its 90° geometry delivers clean, reliable chamfers, helping improve fit and surface finish across a wide range of projects. This countersink is well-suited for engineers, tradespeople, hobbyists, and workshop professionals who demand consistent results.

A hole in metal should always be deburred with a countersink, as the edges of the bore are very sharp. Deburring with this tool helps prevent cutting injuries and contributes to a flat surface. If the screw is to be countersunk into the workpiece, the hole is pre-machined with a countersink, and then drilled conically to allow the countersunk screw head to sit flush with the surface.

• Precise 90° geometry: Produces a clean conical edge for reliable deburring and uniform chamfers, improving surface finish and fit.
• 31,0 mm countersink head: Large head size enables efficient material removal and stable cutting for a consistent chamfer.
• M 16 shank for secure mounting: Durable interface provides a stable, reliable operation in standard tool holders.

Used correctly, the BAER HSSG 90° Countersink helps you finish holes safely and professionally, simplify assembly, and achieve flush screw seating with confidence in every project.
