BAER HSSG 90° Countersink 20,5 mm (M 10)

The BAER HSSG 90° Countersink is a precision tooling accessory designed to deburr and chamfer metal bores with a 90-degree angle. It’s ideal for engineers, technicians, tradespeople, hobbyists, and DIY enthusiasts who need clean, safe holes and a professional finish. Use it to create tapered offsets or to deburr holes so they’re safe to handle and ready for assembly.

When screws are countersunk, this tool pre-machines the bore to the correct taper, ensuring the screw head sits flush with the surface for a neat, flat finish. The result is safer edges, easier assembly, and a high-quality look across a wide range of projects.

• Precise deburring and chamfering: Removes burrs and sharp edges from bores, reducing the risk of cuts and improving how parts fit together for reliable assemblies.
• Flush seating for screws: 90° countersink geometry creates a clean, flush screw head so the surface remains smooth and visually professional.
• Exact size and shank specification (20,5 mm, M 10): Delivers consistent, repeatable results with a defined size and alignment for dependable performance in standard setups.

This countersink supports efficient workflows by delivering safe hole edges, accurate screw seating, and durable, repeatable performance—helping you finish projects faster with consistently professional results.
