In today's review, we're looking at the Makita DTD152Z 18V cordless impact driver. Measuring in at 137mm in length from socket to end cap with a 79mm width and 238mm height, the Makita DTD152Z is one of the more compact brushed cordless impact drivers from Makita at roughly half the price of their brushed offerings.

165Nm of torque!
However, the DTD152Z's claim to fame is in its 165Nm torque output. To put things into perspective, your average sedan's wheel lug nuts only require up to 110Nm of torque to fasten. Compared to Makita's top-of-the-line brushless 18V impact driver, the DTD148Z, the DTD152Z is only 18mm longer and just 10Nm shy of the DTD148Z's maximum 175Nm torque. This makes the DTD152Z an excellent contender in the price-performance category between models.

The DTD152Z is rated for machine screws from an M4 - M8 size, standard bolts from M5 - M16 size, high tensile bolts from M5 - M12 size and coarse threaded bolts from 22 - 125mm in length. The DTD152Z also has a no-load speed of 0-2,900rpm and a 0-3,500 impacts per minute (ipm). Weight-wise, the DTD152Z weighs in at 910g and 1.21kg with an 18V 3.0Ah battery attached. This really won't weigh you down even if you have to work with it day in and day out.

During test, we noted that the impact function will only activate when the bolt or nut is stuck regardless of the trigger pull. Hex bits also slide in and out of the collet chuck smoothly simply by lifting up the collar regardless of how much torque they've been put through.

As a side note, we noted that some of Makita's other regional sites would list the DTD152Z as having the "no need to pull bit sleeve for bit installation" bulletpoint which isn't quite the case, try as we may - the bits aren't going in (or out) if you don't lift up the collet collar.

The DTD152Z also feature the twin LED job lights are super-bright and does a great job at lighting up the immediate workspace with a very wide and very white LED light. It also works with a pre-glow and a 10-second afterglow dimming function.

Similarly, the DTD152Z is also blessed with the Makita Extreme Protection Technology (XPT). Makita doesn't list down any IP-ratings, just the fact that XPT offers 'enhanced dust and drip-proof performance' and a mini disclaimer in their catalogue. We tested with some typical construction dust and some water droplets and the DTD152Z doesn't seem the least bit perturbed by the fact that it's covered in dirt or dripping with water.

The air flow from the DTD152Z also does tend to get really hot even with no load - Makita claims superior cooling efficiency as the reason for the hot air existing the tool and from how cool the tool runs, we think that explaination is reasonably accurate. 

Like all of Makita's tools, the DTD152Z also comes with really with grippy, rubberised design that is both comfortable in the hand as well as providing an added level of assurance when using the tool. The raised molded rubber also acts as bumpers to protects the DTD152Z during every day use.

Conclusions?
Compared to an impact drill-driver, the Makita DTD152Z is very specialised tool as it's designed primarily to drive screws or bolts - you might be able to get away with using a drill-driver for lighter applications, but when it comes right to it, nothing beats a impact driver at what it does best. If part of your job requires driving self-tapping screws into hardwood or concrete or nuts and bolts into metal, then the DTD152Z might be right up your alley. 

You might also want to consider the DTD152RFE or the DTD152RME, that represents a better value as it comes with a rapid charger and two 18V 3.0Ah or 4.0Ah batteries respectively.
