A benchtop lathe for home improvement and hobby machining, the ZHRUI All-Metal Miniature Lathe handles precise small-part turning. Solid metal construction and fine handwheel control bring confidence when finishing models and jewellery components. Is it the right addition to a home workshop for model-makers and small-scale craftspeople?
⚡ At a Glance
- • Cutting Quality: Smooth, accurate turning with reduced flex and consistent concentricity on small workpieces
- • Best for: Hobbyists, model-makers and small-scale jewellers working with soft metals and plastics
- • Not ideal for: Heavy industrial machining or large-diameter work above 50mm
All-metal headstock and motor case combine with dovetail slots and square-nut fixings for stable, repeatable cuts. Fan-cooled motor reaches up to 20,000 rpm for fast finishing on small parts.
Accurate Small-Part Turning – Thanks to All-Metal Construction and Dovetail Connections
All-metal motor case, headstock and bed reduce flex and vibration, while dovetail connection and square-nut fastenings keep components aligned during use. Handwheels use a 0.02mm scale to assist fine feed control.
Reliable concentricity and repeatable cuts make delicate model work and jewellery finishing simpler and more consistent.
Fast Finishing – With 20,000 rpm Fan-Cooled Motor
High-speed motor rated at 12V/3A (36W) includes a built-in fan for cooling, allowing sustained operation at top spindle speeds up to 20,000 rpm. Power supply accepts 110–240V via the switch-mode adapter.
Quicker stock removal and finer surface finish on soft metals and engineered plastics reduce time spent on post-turning work.
Flexible Clamping Options – Thanks to Three-Jaw Chuck, Four-Jaw Chuck and Collets
Workpieces can be held by a three-jaw or four-jaw chuck, with collets covering 1–6mm and jaw gripping ranges of 3–30mm (positive) and 3–50mm (opposite). Chuck fixation uses a hexagon nut for secure clamping.
Secure gripping across a range of diameters and lengths up to 150mm allows turning of small rods, cylinders and decorative parts without frequent re-clamping.
✨ The 4 Key Reasons for ZHRUI All-Metal Miniature Lathe

❓ Frequently Asked Questions
Q: Can the lathe handle metals or only wood and plastic?
A: Soft metals such as gold, silver, copper and aluminium can be turned, along with acrylic and engineering plastics, using the supplied chucks and turning tools.
Q: What is the largest workpiece that can be mounted?
A: Maximum diameter is 50mm with a centre height of 25mm, and maximum supported length is 150mm; collets cover 1–6mm for smaller diameters.
Q: What are the power and safety features?
A: Motor runs at 12V/3A (36W) supplied via a 110–240V switch-mode adaptor, and the transformer includes over-current, over-voltage and over-heat protection.
🏆 Our Verdict
Hobbyists, model-makers and small-scale jewellers will benefit from accurate small-part turning and secure clamping. Durable all-metal construction paired with a fan-cooled 20,000 rpm motor delivers precise finishing and material versatility. Cost-conscious workshops should weigh needs, though robust build and precision controls indicate good long-term value.
