Expert Buying Guide on Hammer Drills

 

Commonly found at construction sites, the power tools described in the best hammer drill reviews simplify hole drilling into brick walls, blocks, stone and concrete foundations. Combining the strengths of a hammer and a drill, the hammer drill utilizes chuck vibration and bit spin to deliver short, rapid thrusts that help pulverize and chip away material just like a jackhammer. Aside from taking note of the brands and models on the market, you also need to know what essential elements make a good quality roto hammer or rotary hammer drill.

Best Hammer Drill

Mode Switch

Some of the top rated hammer drills 2017 are equipped with a mode switch that enables you to choose between different drilling modes.

Dual mode units are small yet have more than enough capability to accomplish repetitive masonry chores easily. They function both as a rotary drill and a rotary hammer drill. They are the perfect size for many wood and metal tasks, as well when used with a keyed chuck adaptor.

At the flick of a switch, a three-mode rotary hammer drill can do regular rotary drilling, rotary hammer drilling and chiseling. Typically larger than two-mode models, a three-mode rotary hammer drill comes with two more symbols on its mode switch. The chiseling mode enables the tool to work like an electric chisel, which hammers without rotation, while the rotation mode enables straightening of the chisel bit prior to engagement of the chisel mode.

 

Robust Chuck

The element that grips the drilling accessories is called the chuck. The chuck is the end of the drive shaft where power is transmitted. All the products in the best hammer drill reviews are equipped with Special Drilling System (SDS) chucks made of quality plastic.

The SDS locks in place accessories with an SDS shank. SDS chucks are available in a range of styles and sizes. SDS-Max and SDS-Plus are the most common, which come with their own matching drill bits. Make sure the bit doesn’t fall out while still being able to slip back and forth.

 

Impact Energy and Drilling Performance

The best hammer drill 2017, whether two- or three-mode, generates more than enough impact energy and beats per minute to do its job efficiently. To assess the level of hammering action, you should compare the beats-per-minute (BPM) and impact-per-minute (IPM) of your prospect tool.

Two-mode rotary hammer drills offer an impact energy range of 1.3 to 2.5 joules, while being able to operate up to 5,000 BPM. The maximum drilling capacity in masonry is about 20mm. In wood, it is approximately 30mm and generally 13mm in metal.

Three-mode tools offer an impact energy between 2.5 and 6.5 joules and up to 4,500 BPM. In masonry, they can drill up to 28mm using a drill bit and up to 90mm used with a core cutter, up to 32mm in wood and 13mm in metal.

 

Solid Features

Most rotary drills are built with a jampot housing into which the components are inserted and with a lid screwed down to seal everything in. This element needs to be durable to ensure effective alignment of the internal components plus a structurally sound tool.

A pistol-grip handle on small units and a D-handle on heavier-duty machines are ergonomic styles. A Side Handle with shock-absorbing capabilities provides stability and stops rotation.

A depth stop ensures precise drilling and is especially useful when you have to drill holes on material that the tool can’t go through.
