VEVOR UM30 Manual Pipe and Tube Bender with 14 Dies: specs and uses

The VEVOR UM30 is a manual bending machine for metal pipe, tube and flat bar. It uses a long lever handle instead of a motor or hydraulics, and ships with 14 dies, so a single machine can handle several shapes and sizes. VEVOR lists uses in HVAC and refrigeration maintenance, auto repair, metal furniture and construction work.

What it can bend

VEVOR gives these limits:

• flat steel or steel plate up to 2 inches wide;
• hollow round pipe up to 0.65 inch outside diameter;
• round steel tube up to 1 inch outside diameter;
• low-carbon steel under 0.2 inch thick;
• aluminium under 0.4 inch thick.

The maximum bending angle is 200 degrees. The listing says the machine works with steel, iron, copper and aluminium. Softer metals such as copper and aluminium are generally easier to bend than steel, and the real limit depends on wall thickness and the radius you want. Treat the listed figures as the ceiling.

The 14 dies

The set has two groups of seven. There are 7 bending dies and 7 round pipe dies, each in 1", 1-1/4", 1-1/2", 1-3/4", 2", 2-1/2" and 3" sizes. VEVOR says they suit flat bars, round pipes, solid square pipes and solid round pipes. The die size sets the bend radius, so a bigger die gives a gentler curve. A die that matches the workpiece also helps prevent flattening or kinking in hollow tube.

Lever and grip

A long handle gives leverage, which VEVOR describes as labour-saving: the longer the lever, the less force the user typically needs at the grip. A non-slip rubber grip aims to keep your hands secure while you pull. The bender is made of high-strength carbon steel.

Size and weight

The listing gives dimensions of 48.4 x 47.0 x 17.7 in and a weight of 65.9 lb (about 30 kg). That is a workshop tool rather than a portable one. It typically needs a bench, floor space and a secure way to hold it steady, and the manual should say how to mount or position it.

Who it suits

It suits home workshops, maintenance work and small fabrication jobs where bends are made one at a time, such as railings, brackets, frames and refrigeration or air-conditioning line work. Heavy production work or thick-walled tube typically calls for hydraulic or powered benders.

What to check before you buy

• Material and size: compare your pipe or bar to the limits above, wall thickness included.
• Die match: confirm you have the right die for the outside diameter and shape.
• Space: allow room for the machine and for the handle's swing.
• Mounting: plan how to keep it stable while bending.
• Upkeep: check the manual for lubrication, storage and rust prevention.
• Protection: wear gloves and eye protection, and keep hands away from pinch points.

The short version

• VEVOR UM30: a manual bending machine with 14 dies.
• Bends flat bar, pipe and tube in steel, iron, copper and aluminium, up to 200 degrees.
• Dies from 1" to 3" in bending and round pipe sets.
• Carbon steel construction, long lever handle and non-slip grip.
• 65.9 lb, with a large footprint, so it needs workshop space.
