Makita DHR242Z Cordless Drill Review

We really hope that you love the products that we recommend. Just so you know, ToolsReview may collect a share of sales or be compensated through the links on this page, but we think it’s a fair trade for the long hours of research that we put in.

The Makita DHR242Z is a high performance, cordless drill that combines several drilling functions in one unit: hammer drilling in hard materials such as brick, concrete and masonry; drilling without impact in wood, metal, ceramic and plastic; and chiselling. As a result of the longer bit guide, stability whilst drilling is increased; consequently, the Makita DHR242Z is capable of taking on some pretty challenging drilling tasks, all whilst maintaining impressive levels of control, precision and power.

All models in the Makita DHR242 range are 24mm cordless combination hammers powered by an 18V Li-ion battery. The innovative brushless motor provides greater efficiency and an increased rate of productivity, reducing energy loss by 30% giving longer run times between battery charges, whilst the Quick Change Chuck (QCC) makes switching to standard straight-shank drill bits a quick and easy process.

Benefits of a brushless motor 

Brushless motors: longer battery life, shorter charging time and greater power. What’s not to like? 

Brushless motors key benefits

Practicality: The electronically-controlled 18V brushless motor in the Makita DHR242 uses energy efficiently to match the torque and RPM output to the changing demands of the application.

Efficiency: When Makita’s brushless motor is combined with their 18V Li-Ion battery, use-time is maximised; power is increased and charging time is reduced. Now that’s some seriously efficient energy production! 

Durability: Use of the brushless DC motor slows the rate of heat production, which in turn reduces the temperature of the drill housing, even during sustained periods of use.

  • Fast charging, long-lasting

The innovative design of Makita’s brushless motor is engineered to be up to 50% more efficient than a comparative model. A fully charged 18v Li-Ion battery will last longer and charge faster – lasting almost twice as long as it would if used alongside a standard brush motor. 

  • Less Friction, More Torque

No brushes mean no friction. Without any resistance, the design of a brushless motor allows for a greater level of torque to be produced: the greater the torque, the less power required, which in turn extends the longevity of the Makita DHR242, as the likelihood of day-to-day wear and tear and consequent maintenance is reduced. 

Powering the Makita DH242Z

The Makita DH242Z includes the hammer drill only; a battery and charger will need to be purchased separately. 

Makita batteries: key features

  • Makita claims their Li-Ion batteries offer unbeatable performance and functionality when compared to Ni-Cad or Ni-MH batteries. 
  • Li-ion batteries have no memory effect. 
  • Upon first use, Makita batteries require an initial charge of approximately 6 – 8 hours. 

The Makita DH242Z is compatible with the following Makita Li-ion batteries:

  • BL1830 Makita BL1830 18V LXT 3.0AH (Around £30-£35)
  • BL1840 Makita BL1840 18V LXT 4.0AH (Around £40-£45)
  • BL1850 Makita BL1850 18V LXT 5.0AH (Around £50-£55)

Pros and Cons

Why we like the Makita DHR242Z 

  • 3 drilling functions to choose from 
  • It comes with a side handle and depth stop as standard
  • Generous warranty period (online registration required)
  • Multiple benefits of a brushless motor

What could be improved upon

  • Stiff operating switch – after a few uses the switch should move freely between the three drilling modes however initially it will require slightly more force than you’d expect
  • Battery and charger not included
  • It’s a bit pricey; there are deals to be had, but you’re still looking at between £160 to £200

Frequently asked questions

How long is the warranty on the Makita DHR242Z?
The warranty for the Makita DHR242Z is potentially 3 years. Providing you go online and register your Makita DHR242Z within 30 days of purchase, you will receive a two-year extended warranty added to the standard one-year factory warranty. Without registering, only the standard 12-month Makita factory guarantee will apply.

Does the Makita DHR242Z vibrate? 
Like all power tools, the Makita DHR242Z vibrates, however, the unique rubber joining construction process on the drill body protects the internal components of the DHR242Z by significantly reducing the level of vibration, and the vibration-absorbing handle ensures a secure and comfortable grip
