MAKITA DHR171Z 18v Brushless SDS Plus Rotary Hammer Drill BODY ONLY

DHR171Z Product Overview

The Makita DHR171 is a 17 mm cordless rotary hammer powered by an 18v LXT Li-ion battery (sold separately). The brushless motor is precision-engineered to be up to 50% more efficient than a comparative model. This means a fully charged 18v lithium-ion battery will last almost twice as long as a product running on a standard motor. It also features constant speed control, forward and reverse rotation plus an LED job light for working under low lighting conditions.

ExpertOur Expert Says…

The Makita DHR171Z is a 17mm cordless Rotary Hammer powered by an 18v Li-ion battery (not included) to deliver up to 1.2 Joules of impact energy and 4,800 impacts per minute. The variable speed trigger allows the operator to adjust the speed based on the material or application and the constant speed control automatically applies additional power to the motor to maintain speed under load. The brushless motor eliminates carbon brushes enabling the motor to run cooler and more efficiently for longer life and generates less heat build-up, making this tool ideal for prolonged use in high production applications.

This is a Makita Body Only tool which is not supplied with a battery and charger.

FAQs
FAQs
What should I look for when buying a Cordless SDS Plus Hammer?

Cordless SDS Plus Hammers are tools which pack a lot of punch. They’re designed for driving into masonry, which means that they need to rotate as quickly as possible. On top of that, because their primary role is as a hammer drill, the impact rate – measured in either impacts per minute (ipm) or blows per minute (bpm) is definitely an important characteristic to consider. You should also check the maximum drilling capacity, which determines how far the tool will go into the material you’re working with.

What's the difference between SDS and hammer drills?

The main differences are in the kind of drill bits they use and the amount of power they can bring to a task.  Slotted Drive System drills use bits with slots or indentations and a pair of sprung ball bearings at the end of the shaft, which ensure a snug fit into the chuck. The fact that SDS drills usually have faster rotations and provide more blows per minute sets them apart from a ‘traditional’ hammer drill and makes them particularly suitable for tougher drilling tasks, such as driving into concrete.

What's the difference between SDS Plus and SDS Max?

One significant difference between these kinds of tools is the size of the shank. SDS Plus bits typically have a 10mm shank, while SDS Max is 18mm. This means that an SDS Max tool can use SDS Plus drill bits with an adaptor, but SDS Max bits aren’t ‘backwards’ compatible. The other main difference is that an SDS Max drill has even more power than an SDS Plus tool and is designed for working on tougher jobs than you might use the SDS Plus machine for.

Which is better: brushless or brushed drills?

Brushed motors use carbon brushes to transfer power from the fixed part of the motor to the rotor. This creates a reliable and relatively inexpensive motor, but brushed motors do require regular maintenance, in order to either clean the brushes or replace them as they wear out. A brushless motor, by contrast, uses a magnet mounted on the rotor to generate the power and electrical switching to perform the function carried out by the brushes. The additional complexity of the motor’s working means that brushless motors are usually more expensive than brushed.

However, eliminating the brushes also eliminates internal friction and maintenance, meaning that brushless motors offer both increased power and a longer working life. Brushless motors also generate less heat and noise and so, on balance, are considered superior to brushed motors.

Which voltage should I choose?

That depends entirely on what your SDS Plus Hammer needs to do. One useful rule of thumb is to remember that the higher the voltage of the tool, the more it should be able to do. As an example, a 12v machine will usually have a drilling capacity in concrete of less than 15mm; the new 54v tools from DeWalt can drill to 30mm. We also have 18v, 36v and 40v options, from leading brands including Hikoki and Makita.
