The first time I picked up the Bosch I found that it fit my hand like a glove with its new handle design. The people at Bosch did a great job of designing a drill that feels like it is lighter than it is and yet provides a reported 650 inch pounds of torque. How much power these drills really deliver is another story but the Bosch 37618 (clever naming) is definitely in the same power league as the DeWalt DCD970 and the Milwaukee 2611.
The drill chuck is the best I have seen with any drill I have used over the past 20 years by a wide margin. There is absolutely no runout and in operation it feels smooth as silk. It holds bits very well and does not loosen with vibration which is a problem I have experienced with the Hitachi drill chucks and to a lesser degree the Makita chucks.
The side handle can be positioned anywhere that works the best and this is important to me as I often am using the the drill in a tight space where the side handle cannot be straight out from the side. Makita and DeWalt has also stuck with this design and as the saying goes if it ain't broke don't fix it.
The lithium batteries provide a lot of charge and are above average in performance. Bosch like everyone else also makes half size batteries but in my experience in high torque use the smaller batteries last about 1/4 as long for some reason. Recharge time is average which is an area where too much emphasis is placed anyway. Faster charges with NiCad and NiMh batteries shortened their life dramatically so charging a lithium ion battery in half the time as claimed by some like Makita, may not be good for the health of the batteries which are not cheap to replace.
Torque is very good with the low speed high torque setting and is great for most situations but not all. When using a medium to large hole cutter a medium torque and speed range setting (as provided by DeWalt with the DCD970) is usually the best in terms of speed and clean cutting without a lot of power cutouts. Lithium ion battery packs cut power to the motor when they sense to much draw is occurring. When this happens if feels like the clutch is slipping severely and the drill chatters. This is quite apparent with the Milwaukee 2601 and the consumer grade Makita BDF452HW drills and the Hitachi drills we have.
With cordless there are more things to consider than with a corded drill and when you add lithium ion batteries to the mix the actual power on the job to the drill bit varies a great deal between the different drills we use. Driving screws or drilling small holes in masonry and the difference is hard to notice and a lightweight 18v or even a 12v drill may get it done. When boring large 3" to 6" holes in wood or masonry the top of the line drills like the Bosch 37618 are the best tool for the job if you want to use a cordless lithium ion powered drill.
My guys saw a big difference in drill performance when we switched first to using the Milwaukee Big Hawg hole cutters and then later to the Blue Boar TCT hole cutters. They could cut a hole more than twice as large but they had to pay more attention to drill speed and the torque setting. This Bosch is capable of making 6" holes in thick plywood and even in brick veneer on OSB when used with the right hole cutter. If you instead use self feed bits or bi-metal hole saws your results will suffer along with the drill speed and the number or holes per battery charge will be a whole lot less.
BLUE BOAR TSF12 12 Piece High Performance Tungsten Carbide Hole Saw kit 2-1/4" Cut Depth. Cut 10x as fast and using 1/40th the battery power. Cordless Drills cut holes 3x as large versus bi-metal hole saws. Deep side gullets for fast plug removal
This is one drill that you need to go to a store and pickup and feel its heft in your hand and if possible run the drill and you will want one whether you actually need a new drill. If choosing another lighter and lower power lithium ion powered drill be aware that lithium adds to the potential power available but it also reduces significantly the peak power available to the drill motor. In high torque = high current draw situations the difference will be most noticeable and have the greatest impact on drill performance. Best to have as much power as you can find in an 18 volt drill if you want one drill you can use for everything. This Bosch is one of very few that I can unreservedly recommend.
