Four Post Shears

Bar Shear

Hot Shear

Hot Shear




The Advanced Machine Design Company Four Post Hydraulic Bar and Billet Shear is the most economical of our bar shear designs while still  producing the highest quality shear cuts available.


The four post bar and billet shear design incorporates our standard hydraulic bar shear features. This includes our patented circuitry that controls the Back Support and Hold Down System, eliminating “bar slap”, extending knife life, and producing the highest quality shear cut available. Optional integrated induction heating systems are available for two and four post bar and billet shears to eliminate stress cracks in cut material.


The AMD four post hydraulic bar shear uses heavy duty tooling that prevents scale buildup in the knife pockets. The knife design also allows for the cutting of unusual shapes and structural profiles. Our tooling manipulator option eliminates any heavy lifting, making knife changes quick, safe and easy.


Our four post bar shears are designed and built to be rugged, versatile, efficient, and economical.  In over 37 years of machine building, not a single AMD Shear has been permanently removed from service due to machine failure. Off the shelf components are used whenever possible, meaning less expense and less downtime.  Shears can always be retrofitted with the latest controls and hydraulic upgrades to keep the machines running effectively for many years to come.
