VEVOR 1-1/4 Inch SDS-Plus Rotary Hammer Drill: features, specs and uses

The VEVOR 1-1/4 inch SDS-Plus rotary hammer (model Z1C-DS-32HE) is a corded tool for drilling and chipping in concrete, brick and masonry. It combines rotation with a hammering action, which makes it quicker in hard materials than an ordinary drill. Here is what its specs mean and what to check first.

What a rotary hammer does

A standard drill turns a bit. A rotary hammer also drives the bit forward and back many times a second, so it breaks up masonry as it turns. That is why it is the usual choice for holes in concrete or for light demolition. It typically uses SDS-type bits rather than round-shank ones.

Motor and impact energy

VEVOR lists a 13A motor rated at 840W, with 5.5 joules of impact energy. Impact energy is a rough measure of how hard each blow hits. Higher figures are generally better for larger holes and chiselling. The maximum drilling diameter is 1-1/4 inches (32 mm). The tool runs on 110V. The listing's feature text also mentions a 1500W figure, while the specification table gives 840W, so confirm the figure with VEVOR.

VEVOR says the motor uses heat-resistant copper wire to allow longer work, along with a heat dissipation structure to extend service life.

Four function modes

VEVOR describes four functions, switched by two buttons:

• Drill only, which the listing suits to wood and steel.
• Hammer only, for concrete and brick.
• Hammer drill, for heavy-duty work.
• Chisel position adjustment, to set the chisel at the angle you want.

Speed and impact rate

A speed control has settings from 1 to 6. The listing gives a no-load speed of 940 rpm and a maximum impact rate of 4,300 blows per minute. Lower speeds typically help start a hole accurately, while higher ones suit continued work.

Vibration control and handle

VEVOR describes a double vibration control design intended to reduce strain on the user, and a 360° adjustable handle for comfort and control. Hammer tools still vibrate, so follow the manual's guidance on breaks and protective equipment.

SDS-Plus chuck

The SDS-Plus chuck allows tool-free bit changes, and the bit locks in while still moving slightly, which helps the hammer action. Only use SDS-Plus bits.

What's in the box

The set includes the hammer, three drill bits, a flat chisel, a point chisel, grease, two carbon brushes, a dust cover, a wrench, two depth gauges and a carrying case. VEVOR advises greasing regularly for proper function. The tool weighs about 11 lb (5 kg), measures about 15 x 10.1 x 3.3 inches (38 x 25.7 x 8.5 cm) and has a 2 m (78.7 inch) cord.

Who it suits

It suits homeowners and tradespeople who drill anchor holes, remove tiles or break up small areas of brick or concrete. It is a mid-sized tool, so very large demolition jobs call for a heavier machine.

What to check before you buy

• Hole sizes: compare the 32 mm maximum with the holes you need.
• Bits: you need SDS-Plus bits, and some are supplied.
• Power: it needs a suitable 110V outlet, and check the cord length against your site.
• Weight: 11 lb gets tiring overhead.
• Safety gear: wear eye, ear and dust protection and follow the manual and local rules.
• Upkeep: carbon brushes wear and the tool needs regular grease.

The short version

• A corded SDS-Plus rotary hammer, 13A and 840W as specified, with 5.5 J impact energy.
• Four function modes and variable speed from 1 to 6.
• 940 rpm no-load speed and 4,300 bpm maximum impact rate.
• Vibration control, adjustable handle and carrying case.
• Three bits, two chisels and spare carbon brushes included.
