Choosing a benchtop metal lathe comes down to a few specs. Swing over the bed sets the largest diameter you can turn. Distance between centers sets the longest piece you can hold. Motor power and top speed affect how well the machine handles metal, and chuck size limits the stock you can grip. Weight shows whether the lathe fits on your bench. This page puts 16 products on one spec sheet so you can compare these numbers directly and see which gaps the maker does not publish.

Top swing and motor power for a bench lathe
The SHENGJINSH 8.7 × 23.6 in model has an 8.7 in swing over the bed, tied for the largest on this page. Its 1100 W motor is the top motor rating listed here. The spindle runs 0-3000 RPM in high gear and 0-1500 RPM in low gear, with forward and reverse. That range covers most small metal turning and threading jobs.
The listing gives a 4.9 in three-jaw chuck and a 1.5 in spindle bore, which suits small round and square stock. It has an emergency stop button and an LED speed display. The listing also notes a cast iron body, metal gears, a turret post for quick tool changes, and a center rest for longer pieces.
The listing does not give a weight or a warranty term, so check both with the seller before you buy. The weight is not listed, so plan for a sturdy bench.
VerdictA strong first pick for small to medium hobby metal work if the listing details fit your bench.
Longest bed on the page with gearless threading
The INTSUPERMAI S028501 has the longest distance between centers on this page at 39.37 in, or 1000 mm. Its swing over the bed is 8.27 in, and the chuck is 4.92 in. The spindle runs 50-2500 RPM on a brushless 1100 W motor. The listing calls the drive gearless, using a belt.
The listing says you switch between metric and imperial threads from the control panel, not by changing gears. It includes three-jaw and four-jaw chucks. It also lists a spindle precision of 0.01 mm and a telescoping scale for measuring. The listing does not mention an emergency stop switch.
No weight or warranty is listed, so check both before buying. Its top speed of 2500 RPM is lower than the 3000 RPM models here. Choose it if you need long stock capacity and a gearless thread setup.
VerdictA capable long-bed option for hobby work, provided the lower top speed suits your jobs.
Long workpiece capacity with a heavy frame
The VEVOR TQ2275 lists an 8.66 in swing over the bed and 30 in between centers. That lets you turn longer shafts, lead screws, and pipe in one setup. It has a 1100 W motor and a 3000 RPM max speed. The listing says the speed is variable, so you can match it to the material without changing gears.
The listed weight is 159.84 lb, which is heavier than the 103 lb VEVOR 7 × 14 on this page. The emergency stop switch and chuck guard interlock cut power when the cover opens. The listing also covers turning, drilling, threading, and knurling on iron, aluminum, copper, plastic, and wood.
The listing names 8 metric pitches from 0.5 to 2.5 mm and 8 imperial pitches from 10 to 44 TPI. No chuck diameter is listed. This model fits buyers who want long-part capacity and a wide thread range on a bench machine.
VerdictA good fit for longer workpieces and thread work, though it is heavy for a bench.
Automatic feed and gearless drive, but heavy
The VEVOR TQ2275S lists an 8.7 in swing over the bed and 30 in between centers. Its 1100 W motor gives strong torque, according to the listing. The speed runs 0-1250 RPM in low mode and 0-2500 RPM in high mode, so you can pick a range for rough or fine cuts.
This model uses a gearless drive, which the listing says picks the transmission ratio automatically. You set cross feed with buttons for automatic feeding, and it supports automatic threading and fixed outer diameter cuts. The listing describes a cast iron and carbon steel plate structure for rigidity.
The listing does not show an emergency stop switch or a chuck diameter. Choose it if you want automatic feed and a gearless setup, and you have room for a heavy machine.
VerdictA solid automatic-feed option for shops with space, though it is one of the heavier models here.
Brushless motor and auto feed for hobby use
The INTSUPERMAI S028353 uses an 1100 W brushless motor that runs 50-2500 RPM. The listing says the brushless design needs no carbon brush replacement, which lowers upkeep. It also uses a belt drive and an electronic leadscrew, so you can switch thread types without changing gears.
A 4.92 in three-jaw chuck and a 1.50 in spindle bore are listed. The X-axis automatic feed runs from 0.01 mm to 0.4 mm. The listing includes an MT2 tailstock taper and 110V wiring for US outlets. Overload protection is also noted, which suits hobby use.
The listing does not give swing over the bed, distance between centers, or weight, so compare those with other models before you buy. No emergency stop is listed. The listing's own use notes point to hobby DIY, model making, and small shop work.
VerdictA useful hobby option with auto feed, but the listing leaves out key size specs.
Best among the reviewed tools
Swing sets the largest diameter you can turn. Among the models that list it, 8.7 in is the top figure here. If you turn wide parts, check this number first, then compare it with the chuck size.
Distance between centers sets the longest piece you can hold between the headstock and tailstock. Long shafts and pipe need a bigger number. Short parts can use a smaller bed without trouble.
Most listings here show 1100 W or 550 W motors and top speeds of 2500 or 3000 RPM. Higher power helps with tougher metal. Check whether the speed range is variable, since that affects finish quality.
Heavier lathes stay steadier during cuts but are harder to move. Several models here list weights from 103 lb to 230 lb. Measure your bench and confirm the listed weight before you buy.
It depends on the work. On this page, the SHENGJINSH 8.7 × 23.6 in model ranks first on our spec score, with the largest swing and top motor power. Buyers who want something lighter may prefer the 103 lb VEVOR 7 × 14 on this page.
Not always. The 1100 W models here offer more power for tougher metal. The 550 W models suit smaller, lighter turning jobs. Check the material and size of your typical project before choosing a motor size.
Swing over the bed sets the largest diameter you can turn. The listings here range from 7.09 in to 8.7 in. If you turn small parts, a 7-in swing may be enough. For wider stock, look for 8.7 in.
Several models here list metric and imperial thread options. Some switch between them from a control panel, while others use metal gears. Check the thread pitch list in each listing to confirm the range you need.
