TK 1630 Square to Round Brake

The Tin Knocker Square to Round Brake is an air-operated machine built for HVAC shops. It produces consistent, professional square-to-round duct fittings in less time and with less effort than a manual hand brake.

It forms both offset and centerline square-to-rounds, and a quick pivot release handle speeds up blade adjustment. The ergonomic design means no bending over a hand brake, and the forming blade is fully guarded with safety glass to keep hands clear of pinch points.

Runs on standard shop air (90–120 psi).
