VEVOR 1200W flex shaft grinder: features, specs and who it suits

The VEVOR flex shaft grinder is a rotary tool in which the motor hangs above the bench and a flexible shaft carries the spin down to a slim handpiece. A foot pedal switches it, so both hands stay on the work. It is made for carving, engraving, polishing, grinding, sanding and drilling on wood, metal, jewellery and stone.

How a flex shaft grinder works

In a handheld rotary tool, the motor sits inside the body you hold. A flex shaft tool moves the motor out of your hand: it hangs from a hook or stand, and an inner cable spinning inside a flexible sheath turns the handpiece. The handpiece can then be slimmer and lighter, more like holding a thick pen, which is why this layout is common for jewellery work, carving and engraving.

The VEVOR motor has a carry bracket for hanging, and a switch on the motor housing selects forward, off or reverse. The motor's label lists 110-120V at 60 Hz.

The motor: 1200W and 30,000 RPM

VEVOR lists a 1200W copper motor that reaches 30,000 RPM. High speed matters because the bits are small: a small burr, grinding stone or sanding band travels a short distance per turn, so it needs many turns per minute to cut and smooth cleanly. For delicate materials and polishing, lighter pressure and an appropriate accessory matter as much as raw speed.

The three-jaw chuck and handpiece

The handpiece is aluminium alloy and ends in a three-jaw chuck that takes shanks from 0.02 to 0.24 inches (0.5 to 6 mm). A collet holds one shank size, while a three-jaw chuck adjusts across a range and is tightened with a chuck key, which is included. The range covers the 3/32-inch and 1/8-inch shanks used by most small rotary accessories, as well as larger ones up to about 6 mm.

Shaft, pedal and size

The flexible shaft is stainless steel and about 35 inches (890 mm) long, which gives plenty of reach from a motor hung above the bench. The foot pedal is made of ABS and PC plastic and has a 51-inch (1.3 m) cord. The motor measures about 4.5 x 5.5 inches (113 x 140 mm), and the whole set weighs about 6.2 lb (2.8 kg).

What comes in the box

Besides the motor, shaft, handpiece and foot pedal, the set includes 31 accessories:

• 8 sanding bands, 6 sanding discs and 8 grinding stones
• 2 sanding band mandrels and 1 mandrel
• 1 spare inner flex shaft cable and 2 spare carbon brushes
• a chuck key, a hex key and a storage box

The spare inner cable and carbon brushes are wear parts. Brushed motors wear their carbon brushes down over time, and inner cables can wear with heavy use, so having spares on hand helps keep the tool running.

Who it suits

This grinder suits wood carvers, jewellery makers, engravers and anyone who polishes or grinds small metal or stone pieces. VEVOR describes it as suitable for both professionals and DIY users. It suits people who work at a fixed bench, where the motor can hang permanently, more than those who need a tool to carry from job to job.

What to check before you buy

• Where to hang it: plan a sturdy hook or stand above your bench for the motor.
• Shank sizes: confirm your existing burrs and bits fall within 0.5 to 6 mm.
• Power supply: the motor is labelled for 110-120V, 60 Hz.
• Consumables: sanding bands, discs and stones wear out; check that replacements in your sizes are easy to find.
• Protection: grinding and polishing throw dust and debris, so plan for eye protection and dust control, and follow the manual.
