Make it Snappy Tools 82度カウンターシンク

Finally, a countersink that actually matches the 82° angle on my screw heads instead of leaving them proud. The hardened steel has held up through a dozen pilot holes without any dulling or chatter.

Bought this to replace a cheap countersink that kept chattering, and the difference is obvious. The 82 degree angle sits flush with standard screw heads so plugs sit perfectly level. Hardened steel still feels sharp after a few hundred holes.

I've been sinking screws into oak for years and always ended up with heads sitting proud. This hardened bit cuts a clean 82° chamfer that matches standard screw heads dead flush, and it still feels sharp after a few hundred holes.
