The Bosch DDB 181 18-volt compact drill driver is the lightest and most compact 18 volt 1/2 inch drill driver on the market and it’s a great value. The DDB 181 is so compact it’s optimized to get into those tight and hard to reach places.
Bosch Flexible Power System
The new Hitachi DS18DSAL is an18-volt lithium-ion compact pro driver. It features Hitachi’s new 18-volt slide-on lithium-ion battery which is 50% lighter than typical NiCad batteries and lasts three times as long. It also features power throughout the life of the battery as opposed to a NiCad which starts losing power as soon as you pull the trigger.
Another feature of the drill is a 22 plus one clutch. This allows the user to select just the right amount of torque for the job they’re doing. For instance, if you were putting in a small screw to install a hinge or something like that, you’d want to set the clutch to 1-2-3 setting which would give just enough torque to set the screw but not spin it out. However, if you were doing a larger job like drilling through a large piece of wood or driving a lag bolt or something that needs a lot of power, you would have to set the drill to allow up to like 400 to 460 amount of torque.
Half Inch Metal Ratcheting
Another great feature of this tool is the half inch metal ratcheting keyless chuck. This allows the tool to change bits very quickly and efficiently and securely fasten them to the tool so that you know they’re not going to slip. With a quick twist, you can remove a small bit, expand the chuck to its widest opening which is a half inch, insert any tool up to 1/2 inch in diameter, then a quick twist. The tool is now securely fastened and will not come out.
The DS18DSAL also features a two-speed switch. In the low-speed, the tool will operate from zero to three hundred and fifty rpm. While in the high speed, it will operate up to 1500 rpm. Why this is important is because when you’re driving your screw or a lag bolt or something that takes an amount of torque, the tool should be operating in the low speed. This allows the tool to offer the full amount of torque to deliver and drive the screw properly. The high speed setting would be used for pilot holes or other drilling or high speed applications where the torque is as important as the speed of the drill to do the job properly.
Everyone knows that after a full day of using a driver like this, the weight can be a serious issue. The DS18DSAL is compacted at only seven point seven inches in length. And weighing just about 3.5 pounds, the tool is very lightweight. It provides enough torque and power to get any job done.
