Strut & Threaded Rod Cutters

Unlike an angle grinder or saw that uses an abrasive edge to grind or tear away metal particles, a Strut Cutter uses high-tonnage mechanical or hydraulic force to push a hardened steel die straight through the material. This creates a clean shearing action. Because the metal is physically separated rather than ground away, the tool runs completely cold—creating zero fire-hazard sparks, zero hot metal shards, and zero airborne metallic dust.

Cutting capacity depends on the model and die set you choose. Most professional bench-top and hydraulic strut cutters are engineered to process standard 1-5/8" x 1-5/8" full-size channels as well as 1-5/8" x 13/16" shallow-profile strut. High-tier industrial units feature interchangeable die blocks, letting you switch configurations quickly to handle varying material wall gauges up to 12-gauge mild steel or aluminum.

Nuts will spin straight onto the rod. Cordless threaded rod cutters feature specialized, dual-sided cutting dies that wrap perfectly around the exact thread pitch of the rod. As the jaws close, they shear the steel cleanly across the valley of the thread without flattening or distorting the surrounding ridges. This completely eliminates the need to manually de-burr, file, or clean the tip with a die tool before assembly.

No, you should never use a threaded rod cutter to cut hardened bolts, rebar, or solid wire lines. The precision-machined cutting dies are hardened specifically to match the thread pitch and metallurgy of standard low-carbon steel or all-thread hanger rods (like Grade 2 or 60,000 PSI tensile strength). Attempting to force the tool through hard fasteners or rebar will instantly chip, crack, or misalign the cutting dies, ruining them for rod work.

Most commercial cordless models (like the Milwaukee M18 or DeWalt 20V lines) feature a multi-sided cutting die block that index to handle the most common electrical and mechanical hanging sizes. Out of the box, these tools comfortably shear 1/4-inch, 3/8-inch, and 1/2-inch coarse thread rods. You simply rotate the die block to line up the slot size matching your material diameter.

It comes down to tool mobility and the physical effort required to make the cut:

• Manual Bench Cutters: Use a long mechanical lever handle to multiply your arm force. They are reliable, require no power source or cords, and are ideal for stationary fab tables, but they require physical effort.
• Hydraulic/Cordless Cutters: Leverage an electric motor or integrated hydraulic pump to do the heavy pulling at the press of a trigger, making them perfect for high-volume production lines and reducing operator muscle strain.

It depends entirely on the rating of your cutting dies. Standard factory dies are built to process mild carbon steel and zinc-galvanized materials. Tough stainless steel workpieces are significantly harder and more abrasive. Running stainless steel through a standard die will quickly dull or chip the edge. If your project uses stainless elements, you must verify your tool is equipped with specialized, high-hardness replacement dies rated explicitly for stainless steel applications.

If the tool begins requiring noticeably more hydraulic cycling time to finish a cut, leaves an excessive flat crush mark on the edge of your strut, or binds during the stroke, your dies are worn out. Many high-quality threaded rod cutter dies feature a multi-sided design. This means when one cutting edge finally dulls, you can simply back out the mounting screw, flip the die block to a brand-new side, and keep working with zero downtime.

When you purchase your fabrication equipment through an authorized channel like Ohio Power Tool, your tools receive full manufacturer protection. Handheld cordless models (such as Milwaukee M12/M18 or DeWalt options) generally carry a comprehensive 3-Year to 5-Year Limited Warranty against factory defects in materials or craftsmanship. Heavy bench-top hydraulic machinery is typically covered under a 1-Year industrial warranty, while consumable cutting dies are excluded.

As an authorized elite distributor and trusted trade sales partner, Ohio Power Tool carries a comprehensive portfolio of genuine cutting accessories. We stock factory-direct replacement threaded rod die blocks, replacement strut shear cutters, standalone bare tools to expand your current battery fleet, extension support stands, and protective tool bags to ensure your field crews maintain peak jobsite productivity.
