There’s a work light placed on the bottom of the grip, that only lights up when you’re pressing the trigger. It thuds into place, just like the gear selector switch behind it.

The big switch behind it to change from hammer to driver to drill mode is really satisfying as well. It’s chunky, clunks round with a positive action, and gives you a huge 24 torque settings to choose from. The torque selector ring behind the chuck feels excellent. It’s not the smallest cordless drill and it definitely can’t fit into as tight gaps as the Terratek 18V, for example. The plastic chuck on the front of this drill seems rather long, and it contributes to the overall length of 215 mm. Weighing in at 1.3 kg, it’s the same as the DeWalt DCD796, but the long body and brushed motor make it feel a little off-balance in comparison. Having a good grip is probably for the best though because this feels like a heavy cordless drill. The extra ridge included on the grip sits nicely between the middle and ring finger and makes it just that bit easier to hold. It’s not just a grippy handle though, there’s also the brilliant ergonomic shape that makes the Ryobi R18PD3 an incredibly comfortable tool to hold on to.

The rubberised sections contain hundreds of tiny plus signs that just seem to grip really well. It’s quite simply the best overmoulded grip on the market if you ask me. If you’ve ever held a Ryobi tool before, you’ll know about their patented GripZone technology.

Some heavy-duty DIYers might moan about the relatively small 1.5 Ah batteries supplied with this drill, but it’s perfectly fine for most small to medium size jobs. It’s not as powerful as the DeWalt or Makita pro-level drills, but for a DIY bit of kit, it’s just the ticket. Overall, this is a dependable and reasonably heavy-duty combi drill. The two batteries that come with this combi drill kit can be used in anything from air compressors to belt sanders, which is impressive. If you’re familiar with Ryobi’s ONE+ battery system, you’ll know that by buying into their stable you have access to hundreds of different tools.

The R18PD3 is one of the best combi drills for DIYers, but it’s not going to challenge the more professional tool brands that take the top spots. The quality of their tools has improved, and I’ve been impressed by a lot of their tools I’ve tested out. These are the only options that make sense.I think that Ryobi have come a long way in the last few years. You can rebuild your power tool battery with new cells, or you can buy a new power tool. Your problem is that a power supply which can deliver this kind of current without blowing up costs more than a brand new drill with brand new battery. Resistive losses are proportional to I^2 which means 50 Amps is 100x more trouble than 5 Amps. The converter will cost $6 and it will explode. So, when you say:Ī boost converter cost about 6$ and the power supply 25$ I've talked with a guy who bought some Chinese boost cnverters on ebay, and of course the capacitors on them exploded when he tried to use them at rated power. A 12V to 18V converter for 50A current would be an interesting design. If the power supply cannot deliver this current, then the drill will not work well, it will stall instead of powering through the job.īesides, boost converters suck at high currents.

It will be alright for a battery, but it will be trouble for a mains-powered power supply. Most likely this stall current will be very high, maybe like 30-50 Amps. Measure the resistance of your motor, and you will know its maximum stall current. Stall current depends only on motor resistance, which you can measure with a multimeter on ohm-meter mode. Maximum current and maximum torque occur at 0 rpm, when the motor is stalled. How many amps does an 18v cordless drill drawĬurrent drawn by a brushed DC motor depends on torque and rpm.
