The saw is a heavy beast and holds a 140mm circular blade which can be bought anywhere so the blade is not the problem. The problem is the power, or lack of power that the motor gives to the rotation, it's just not enough to allow the blade to cut through polystyrene.
The plate can be adjusted to cut up to a 45º angle and locks off properly so that it does not slip off anywhere during the cut. With the maximum depth of a cut being about 40mm.
The handles is nice to grip and there's a second handle/knob that can be used to assert more pressure on the front so that the machine doesn't jump up whilst cutting.
The drill has two settings and offers a 22 torque setting option, using the ring around the key-less chuck to set the torque, the more delicate the work the lower the torque, so 22 settings is pretty good really. Sadly, as with the saw, this drill just doesn't have what it takes in order to do some serious drilling and screwing.
You do get two Ni-Cd rechargeable batteries which, as they are Ni-Cd they are not the best when it comes to keeping the power stored in them... these batteries are supposed to be quick charge using the supplied one hour charger but, if like the ones I had, one hour charge has less power than a community police officer in the UK.
The main tools are not the issue here really as both tools are made as well as any DIYer would expect, if a little heavy with the saw unit. It is the power that the battery fails to offer and the fact that the batteries don't hold the charger for that long, especially when I'm either drilling into something hard or sawing through something that seems to fight back a little.
To be honest there are not that many cordless power saws that can handle a good days work so I never expected this to be any good at all, which I was right in thinking. But the drill should at least be able to bore more than three holes in a brick wall before falling flat..? I mean, it's alright if you only have to put one bracket up per hour as it can handle 2 or three screw holes, but any more and the battery drains quicker than my bank account on a Friday...
This set is on sale these days at about £120, which is way too much and I was glad that I did not have to pay for mine.
This is one drill and saw that are best left on the shelf...
