Aimed at: Professional users, with a bit of an eye on the budget without giving up on performance.
Pros: Impact driver has 180Nm of torque and the combi drill is compact, able and comes with an excellent metal chuck.
In a crowded power tool market it is great to have a niche in which you can dominate. Flex has done this with their famous range of Giraffe wall sanders, chasers, grinders and polishers. So, it is only natural that the company would want to join the competition in the cut throat cordless market too.
This it has done by developing its own lithium ion battery system, complete with sophisticated chargers, heat monitoring and electronic control for tools and chargers. Users would say that these are a minimum for professional quality tools these days, and they would be right. But as I have discovered, the Flex tools I have used match up to current standards and are not a poor relation.
However, in a very brand driven market it is sometimes hard to get the message across, and it is also quite difficult to get end users to think more carefully about their tool choices. On site, I rarely need to top up a battery if I have remembered to charge it up overnight, since my power needs are mostly confined to impact driving and drilling. My observations are that many other trades are in the same boat. But still the view persists that bigger is better. Whereas in fact, I often end up using optional 2.5 Ah battery packs because they are smaller and lighter than 5Ah ones. Surely here is a chance for end users to find ways to get the job done without necessarily paying top prices that premium brands can charge?
The two Flex drivers I was sent for review came well presented in stackable Sortimo L-Boxxes with custom fitted inserts to hold tool, spare battery, chargers and accessories tightly in transit. I like these boxes because they have top and front handles, are very easy to stack and lock together and are as compact as they need to be to contain the tools, so they don’t take up lots of extra space.
First up for review was the PD2G 18.0 Drill driver and hammer. Early impressions are very favourable because the build quality is up there with the best. Clearly this is no budget model and it feels solid and weighty in the hand. The ergonomics of the handling has clearly been thought through with a good rubberised grip on the well-proportioned main handle and a good balance in the hand. There are other strategically placed rubber bumpers on the rear and bottom of the handle so the tool can be stood up or lain down on surfaces without damaging it.
There is a quality, solid metal keyless 12mm chuck which works very well without slipping and is also easy to loosen and tighten. Behind the chuck are two plastic collars, the first to choose the 24 torque positions and the second to select drilling, screwdriving or hammer modes. Both of the collars are robust, move easily without sticking and have sensible grips on them to make adjusting them easy. On top of the drill is a slider switch for selecting high or low gear making speeds from 0- 1650 and 0-380rpm possible. In low speed torque is a very reasonable 70Nm which is enough for most purposes. Trigger arrangement follows the common layout of a push through switch for selecting forward/reverse and a speed sensitive trigger. All works smoothly and the spindle brake works very well too.
The PD 2G has a very good auxiliary handle that is firmly screwed, via tightening clips, onto the front of the alloy gear housing. This can suit left or right handers, but is not adjustable around a collar like some other drills. I also liked the belt hook – as I now sometimes have to use it to hold a tool when I am up on a ladder for example. There is also a handy bit holder that is screwed in opposite the belt hook. Again it can be useful - making it easier to find a driver bit rather than the usual scrabble in a pocket crammed with a whole lot of other bits and pieces.
I liked the smaller 2.5Ah battery at height and in confined spaces, and I found that charging was quick and easy using the diagnostic charger – usually taking about 45 minutes.
While the above drill/driver is good, I wasn’t prepared for the performance of the ID ¼ inch 18.0. It is simply amazing and I worked out why when I looked at the specs – it has an astonishing 180Nm of torque. I have never had it so easy driving concrete screws into dense concrete. It was the Torx driver bits that felt the pressure!
Similarly into wood, even the longest screws I used (150mm) were driven without effort or drama. It really is very good and I liked using it very much.
Like the drill/driver above, the Flex impact driver is very well made, and surprisingly compact in the way that modern impact drivers are. It has a similar pattern of rubberised grip on the handles, motor end and bottom of the handle. So handling and bump protection taken care of. The other controls follow a familiar layout and are thus easy to work with – ergonomics is a strong point on both of these tools.
I used the tools for several weeks on site and I also lent them to a couple of others to garner their opinions. One of the users is a welder who rarely uses cordless tools in his day job, but he was full of praise for their easy handling and they had enough power for him to drill and drive very happily (he used 60mm screws maximum)
The other user had a more demanding project and needed a pair of drivers to get him over a hump because his impact drill had broken and was in the repair shop. He was full of praise for the Flex tools, especially liking the handling and balance and their ability to drive 120mm woodscrews with ease. To say that he was impressed with the impact driver is understating it – I nearly had to wrestle it back off him and I think it is safe to say that he thought it was much better than the (branded) one that was returned from the repair shop.
So, definitely worth a look – my guess is that you will be pleasantly surprised.
