Screw Bench Chain Vise 1/8 to 5 in Pipe Capacity - Heavy Duty

In this review the Screw Bench Chain Vise is presented as a straightforward heavy-duty bench vise for hobbyists and pros who need to grip pipes from 1/8 in to 5 in securely. The single biggest reason to consider it is its large holding range combined with a rugged cast iron frame and neoprene-coated jaws that reduce marring while gripping. It is not a fancy shop fixture, but it reliably holds tubing and awkward workpieces in place for cutting, bending, or welding prep.

Key Features

• Large holding capacity: Clamps pipe and tubing from 1/8 in to 5 in (3.2 mm to 127 mm), so a wide range of plumbing and metalwork sizes are supported without adapters.
• Solid cast iron frame: The rugged base provides stability on a bench, truck bed, or tripod mount to resist twisting under load.
• Neoprene-coated jaws: Soft-coated contact reduces surface damage to pipes while still delivering a firm grip for cutting and bending tasks.
• Crank handle operation: The included crank handle and chain system let one person tighten pipe quickly without excessive fatigue.
• Easy installation: Compact and relatively lightweight, the vise bolts to any secure surface for temporary or semi-permanent setups.

Who It's For

The vise is best for DIYers, plumbers, mobile repair techs, and metalworkers who need a portable, heavy-duty pipe clamp capable of handling large diameters up to 5 in. Its cast iron construction and chain design make it especially useful for jobs where irregular or bulky workpieces must be held firmly.

Those who should look elsewhere include users who need precision machine vices for mill work or integrated multi-jaw setups; this is a workholding tool optimized for pipe and irregular shapes rather than fine alignment or precision fixturing.

Pros & Cons

Pros

• High hold capacity for pipes from 1/8 in to 5 in, covering most residential and light commercial jobs.
• Durable cast iron base and heavy-duty chain give long service life under tough use.
• Neoprene jaws protect pipe surfaces while still providing strong bite for cutting and bending.
• Crank handle reduces effort and speeds up repeated clamping actions.

Cons

• Some buyers report missing hardware or rollers on arrival, so inspect the package and keep replacement parts in mind.
• Not designed for precision alignment tasks; its strength is in holding irregular or large-diameter pipe rather than fine machining.
