A bench vise needs to do more than clamp a board in place. You want steady hold, clean positioning, and enough strength for woodworking, metal repair, pipe work, drilling, and small shop projects. The SEDY Heavy Duty Bench Vise 4.5 Inch is a manual workbench vise with a 4.5-inch jaw width, a 240-degree swivel locking base, and magnetic jaw pads for added surface protection. This review will help you decide if it is the right size and build for your bench, or if you should step up to a larger vise.
Quick Verdict
Rating: 8.4/10
Best For: Home garages, small workshops, DIY repairs, woodworking, light metalwork, and drill press support tasks.
Bottom Line: The SEDY 4.5-inch bench vise is a strong pick if you want a compact, multi-purpose vise with swivel positioning and included magnetic jaw pads. Its main tradeoff is size, since the 3-3/4-inch jaw opening may feel limiting for larger stock or heavy fabrication work.

What Is the SEDY Heavy Duty Bench Vise 4.5 Inch?
The SEDY Heavy Duty Bench Vise 4.5 Inch is a compact manual vise made for a workbench, table, or shop surface. It uses a multi-jaw design, so you can clamp flat stock and round materials such as pipe or small tubing with better control than a flat-jaw-only vise.
The main appeal is its mix of size, weight, and adjustability. You get a 4.5-inch jaw width, a 3-3/4-inch jaw opening, a 2-11/32-inch throat depth, and a 240-degree swivel locking base. That makes it useful for common garage tasks where you need to rotate the workpiece angle instead of repositioning your whole body or project.
The kit also includes two 4-inch thermoplastic polyurethane jaw pads with a magnetic design. These pads are useful when you want more grip or need to reduce surface marks on finished wood, softer metals, or delicate parts.
Who Should Buy It?
Best For
- DIY users who need a sturdy bench vise for small to medium shop projects.
- Woodworkers and repair users who want included magnetic jaw pads for better surface protection.
- Garage owners who want a swivel base for drilling, filing, sanding, cutting, and assembly work.
Skip If
- You often clamp material wider than the 3-3/4-inch jaw opening.
- You need a larger industrial vise for heavy fabrication or repeated high-force work.
- You want a dedicated drill press vise instead of a general-purpose bench vise.
Before You Buy: Check your bench thickness, mounting space, and project size before ordering. The 4.5-inch jaw width is useful for many home shop jobs, but the 3-3/4-inch jaw opening is not meant for oversized stock.
Design and Build Quality
The SEDY vise is built from iron and described as premium gray iron, which gives it the mass and rigidity you want for common workbench tasks. At 10.83 pounds, it has enough weight to feel planted once installed, but it is still compact enough for smaller benches and garage work areas.
The blue and silver finish gives it a standard shop-tool look, while the manual operation keeps the design simple. There are no batteries, cords, or electronic controls, so your main maintenance concerns are clean jaws, smooth screw movement, secure mounting, and rust prevention.
Multi-Jaw Clamping Performance
The multi-jaw design is the key feature if you work with more than flat boards. It is made to clamp flat and round materials, which helps when you need to hold pipe, small tubing, metal bar, wood blocks, brackets, or repair parts.
The 4.5-inch jaw width gives you a broad enough contact area for small and mid-size workpieces. The 3-3/4-inch jaw opening is practical for many home repairs, but it is still a clear size limit. If your projects often involve larger lumber, wide metal stock, or bulky assemblies, a 5-inch or 6-inch vise may be a better match.
240-Degree Swivel Base
The 240-degree swivel locking base lets you rotate the vise so the workpiece faces a better angle. This helps when you are drilling, filing, sanding, cutting, or aligning parts, especially on a crowded workbench.
A swivel base is most useful when it locks firmly. Before applying pressure, make sure the base is tightened and the bench itself is stable. A loose base can shift under load, which can hurt accuracy and increase the risk of tool slip.
Magnetic Jaw Pads and Surface Protection
The included jaw pads are made from thermoplastic polyurethane and use a magnetic design. They are a useful add-on when you need extra grip or want to reduce clamp marks on softer materials.
The jaw pads are not a fix for every surface. Very soft finishes, polished metals, painted parts, and delicate pieces still need care. Test pressure slowly, keep the workpiece centered, and avoid clamping harder than the material needs.
Pro Tip: Keep the magnetic jaw pads near the vise instead of loose in a drawer. You are more likely to use them when clamping finished wood, aluminum, painted brackets, or parts that can show jaw marks.
Setup Tips Before First Use
Install the vise on a solid bench or work surface that can handle clamping pressure. A weak tabletop may flex, shift, or pull fasteners loose when you apply force. Place the vise near the front edge of the bench so longer material can hang down or extend past the work surface when needed.
Before your first project, open and close the jaws fully, check that the swivel lock holds, and make sure the jaw pads sit flat. If you plan to drill, file, saw, or hammer near the vise, confirm the base is tight and the workpiece cannot rotate or lift.
How It Performs in Real Use
For General Garage Repairs
For common repair tasks, this vise gives you a stable third hand. It can hold brackets, small metal parts, wood pieces, and pipe while you cut, clean, glue, file, or assemble them. The 10.83-pound weight and iron construction help it feel more secure than a lightweight clamp-on hobby vise.
For Woodworking Projects
The 4.5-inch jaw width works well for small woodworking pieces, trim, blocks, handles, and repair parts. The jaw pads help reduce marks, but you should still use scrap wood as a buffer when clamping finished pieces or soft wood.
For Round Pipe and Metal Work
The multi-jaw design is useful when clamping round stock. It can help hold pipe or tubing more securely than flat jaws alone. For heavy cutting or high-force bending, use caution and make sure the material is centered, the base is locked, and the bench is strong enough for the load.
For Drill Press or Milling Support
The listing positions this vise for drilling, press, and milling tasks. It can support workpiece holding, but it should not be treated as a direct replacement for a dedicated machine vise when precision, repeatability, or heavy cutting forces matter. For best results, clamp the workpiece securely and keep your hands clear of the bit or cutter path.
Material Safety and Workbench Safety
This is a manual iron bench vise, so the main safety concerns are mounting strength, pinch points, workpiece stability, and tool control. Keep your fingers away from the jaw faces while tightening. Do not strike the handle with a hammer to gain extra force, because that can damage the screw, handle, jaws, or mounting surface.
Use eye protection when drilling, cutting, filing, grinding, or working with metal chips. If you clamp pipe, metal, or irregular shapes, check that the part cannot roll or jump out under tool pressure. The magnetic jaw pads can help with surface protection, but they do not replace correct clamping technique.
Pros and Cons
Pros
- 4.5-inch jaw width gives you a practical clamping surface for many home shop tasks.
- 240-degree swivel locking base helps you position the workpiece at a better angle.
- Multi-jaw design supports both flat stock and round materials.
- Included thermoplastic polyurethane magnetic jaw pads help improve grip and reduce surface marks.
- Manual iron build keeps the tool simple, durable, and easy to maintain.
Cons
- The 3-3/4-inch jaw opening may be too small for larger stock or bulky assemblies.
- It still needs a strong, properly prepared mounting surface to perform well.
- Not the best fit if you need a larger industrial vise for heavy daily fabrication.
Is It Worth the Price?
The SEDY Heavy Duty Bench Vise 4.5 Inch is worth considering if you want a mid-size bench vise with a swivel base and included jaw pads. It offers strong value for the price when your projects are mostly home repairs, woodworking, light metalwork, pipe holding, and general garage tasks.
You get the most value if you need one vise that can handle several materials instead of a single-purpose clamp. The 4.5-inch size keeps it practical for smaller workspaces, while the iron build and 10.83-pound weight give it more substance than very light hobby vises.
It is not the best fit if you regularly clamp wide stock, oversized parts, or heavy fabrication pieces. In that case, a larger 5-inch or 6-inch vise may give you more jaw opening, more throat depth, and a heavier base.
How It Compares to Alternatives
Compared with many 4-inch homeowner vises, the SEDY gives you a wider 4.5-inch jaw and a 240-degree swivel base. That makes it more flexible for small shop work where you change angles often.
If you want a familiar homeowner vise, the Yost LV-4 is worth comparing. If you need more jaw opening and a heavier build, a 6-inch VEVOR bench vise may be a better match. If you want another 4-1/2-inch option, a WORKPRO bench vise is also in the same general category. The SEDY makes the most sense if you want a compact multi-purpose vise with included magnetic jaw pads.
Frequently Asked Questions
What materials can the SEDY 4.5-inch bench vise clamp?
It is made for flat and round materials, so you can use it with wood, metal pieces, pipe, tubing, brackets, and many small repair parts. Use the magnetic jaw pads or scrap material when clamping softer or finished surfaces.
How wide does the jaw open?
The listed jaw opening is 3-3/4 inches. That is enough for many home and garage tasks, but you should measure your common workpieces before buying if you often clamp wider material.
What is the throat depth?
The throat depth is listed as 2-11/32 inches. This affects how far a workpiece can sit below the top of the jaws, so it matters when clamping deeper parts or positioning material for drilling and filing.
Can you use it with a drill press?
Yes, the product is positioned for drill press support and similar shop tasks. For precision drilling or heavier machine work, use proper clamps, keep the vise secure, and consider a dedicated drill press vise when accuracy and repeatability are critical.
Are the jaw pads included?
Yes. The listed included components are 1 bench vise and 2 jaw pads. The pads are 4-inch thermoplastic polyurethane covers with a magnetic design.
Is it suitable for outdoor use?
You can use it in a garage, shed, or covered outdoor work area, but long exposure to rain and moisture can increase rust risk. Store it dry, wipe it after use, and protect the screw and bare metal surfaces when needed.
How much does the vise weigh?
The listed item weight is 10.83 pounds, or 4.92 kilograms. That weight helps stability once mounted, but the final hold also depends on your bench strength and hardware setup.
Who should skip this vise?
Skip it if you need a large industrial vise, a wider jaw opening, or a dedicated machine vise for precision milling. It is better suited to home workshops, repair benches, and small to medium clamping jobs.
The Bottom Line
The SEDY Heavy Duty Bench Vise 4.5 Inch is a solid choice if you want a compact, manual bench vise with multi-jaw clamping, a 240-degree swivel base, and included magnetic jaw pads. It is best for home garages, woodworking, light metalwork, pipe holding, and general repairs, while buyers with large stock or heavy fabrication needs should look at a bigger vise.
