VEVOR ZA-DS-106 20V Cordless SDS-Plus Rotary Hammer: features and specs

The VEVOR ZA-DS-106 is a 20V brushless cordless rotary hammer with an SDS-Plus chuck. It is made for drilling into concrete, brick and masonry, where a regular drill struggles, and it can also drill wood and metal. The kit includes a 4.0Ah lithium-ion battery, a 3.0A charger, three drill bits and a carrying case.

What a rotary hammer does differently

A standard drill only spins. A rotary hammer also strikes the back of the bit with a piston mechanism, so the bit chips away at hard material while it rotates. This is much more efficient in concrete. The impact energy is measured in joules, and VEVOR rates this tool at 1.5 J, which is in the range typically described for light-duty SDS-Plus tools. It's suitable for anchor holes and smaller masonry jobs rather than heavy demolition.

Speed and impact rate

VEVOR lists a top speed of 1000 RPM and an impact rate of 0 to 5100 BPM (blows per minute). The variable speed control lets you start a hole gently and increase the speed as the bit bites. The maximum drilling diameter is 0.6 inch (16 mm). The title mentions a 5/8 inch capacity, which is the largest bit size to expect for concrete.

Brushless motor and heat

A brushless motor uses electronic switching instead of carbon brushes. In general, this means less wear, less heat and better battery use than brushed motors. VEVOR describes the motor as heat resistant, and says a heat-dissipation structure helps extend the life of the tool.

Two modes and reverse

Two functions are listed: hammer only, for chiselling concrete and brick, and hammer drill, for heavy-duty drilling. VEVOR says its dual switch buttons last longer than a single-button system. Reverse helps with starting bits accurately and with removing fasteners.

SDS-Plus chuck

SDS-Plus is a bit system with grooves on the shank that lock into the chuck, letting the bit slide back and forth for the hammering action. Bits can be changed quickly without a key. It requires SDS-Plus bits, so standard round-shank bits will not fit without an adapter.

Size and weight

The tool measures 11.0 x 9.8 x 3.1 inches (about 28 x 25 x 8 cm) in the listing and weighs 8.4 lb (about 3.8 kg). That is manageable for overhead work in short sessions, though you will feel it. VEVOR recommends regular lubrication to keep the tool performing and extend its life.

Who it suits

It suits homeowners and tradespeople who need to drill anchor holes in concrete, remove tiles or break through brick walls without a cord. For heavy continuous use or large-diameter holes, a higher-energy tool is normally used.

What to check before you buy

• Bit type: you need SDS-Plus bits; three come in the kit.
• Hole size and depth: compare your jobs with the 16 mm maximum.
• Battery: a single 4.0Ah battery limits runtime; check whether you'd want a spare.
• Dust and protection: use eye, ear and dust protection, and check for hidden wiring and pipes before drilling.
• Compatibility: the battery system is VEVOR's own; check whether it's shared with other tools you own.
• Upkeep: lubricate as the manual describes.
