Product review: Flex PD2G 18v drill and impact driver

I have looked at a few different tools from Flex over the years. This German company is not a major player in the UK drills market and I don’t expect they are intending to be but they have some attractive looking tools in their range and they seem to be well made.

The Flex PD2G 18v drill and the ID 1/4inch 18v impact driver can be bought individually or, more economically as a kit, sharing batteries and charger. I checked out some typical prices and the two tools together represent a real saving. But before you are seduced by the price you have to take a closer look at what you are getting and see if it is for you.

The drill has a brushed four pole motor and the torque measured at its highest hard reading is 65Nm so it is a lightweight drill not intended for those really heavy duty tasks. Out of pure devilment I did push my luck with it to see when the Electronic Management System kicked in to save the battery and the motor from damage. Happily with the 50mm self feed bit the cut-out did the job well and stopped the drill when things got too hard. Not only did I see no smoke I didn’t smell anything untoward coming from the windings but don’t try this at home. I did it because the drill is going back after the test period.

The impact driver looks like many other impact driv ers out there and I wouldn’t expect it to perform any differently so I was somewhat surprised to find it boasts 180Nm of torque. That puts it at the high end of 18 volt 1/4 inch impact drivers. There is a cut-off point with 1/4 inch impact drivers because the stress placed on the bit holder and the bits, not to mention the screws, means that you really should be looking for a 1/2inch drive after that.

If you are using a machine with this much power you need good driver bits and good quality screws. That said you are not obliged to use it on full throttle all the time. You can simply save that top speed for when you really need it but I wonder how many tradesmen are capable of that kind of restraint. Head down and go for it is more your British style.

  1. so compared to the competition, especially milwaky or makita, how does it play? price to performance ratio seems very good given that you get 5ah batteries. also how do you feel about having a brushed motor while most tools are becoming brushless? is it worth considering?

    Thanks, Josh

    • The brushed motor is cheaper in the short term. We didn’t run this up against the competition. See our 18 volt test which shows the Makita an Milwaukee are the leaders in terms of torque and bang for buck. It depends how much work you do with a drill. If you use one all day long then the brushless is the way to go.

  2. Roger you should try the 10.8v pd2g it is better than anything else in its class by a country mile !
