Bosch PS31-2A 12-Volt Max Lithium-Ion 3/8-Inch 2-Speed Drill/Driver Kit Review

Bosch PS31-2A 12-Volt Max Lithium-Ion 3/8-Inch 2-Speed Drill/Driver Kit

Which company makes the best cordless drills? Different people will have different opinions and answers to the question. But most of us will agree that Bosch is one of the top manufacturers. If you are looking for a cordless drill which is small enough to reach into tight areas and corners, one of their products, the Bosch PS31-2A definitely cannot be left out. So many people have been impressed with the power and convenience of the drill. In this review you will find information regarding the main features of the Bosch PS31-2A, along with some of the pros and cons of the tool.

At just 2.14 pounds, it is by far the lightest cordless drill/driver in its class. The Skil 2414-02, for instance, weighs 2.6 pounds. The Milwaukee 2410-22 has a weight of approximately 2.5 pounds. The Bosch PS31 is also impressively compact at 7 inches in length. Compact in size and lightweight in design, it is perfect for overhead work and confined areas. The Bosch cordless-electric drill is powered by a 10.8V/12V MAX Lithium-Ion battery. In terms of weight and volume, Li-Ion seems to be the best compared to NiMH and NiCad.

The package includes two lithium battery packs with 2 amp hour rating, a plug in charger and a soft case. With the BC330 charger, recharge time is 1 hour. If you want faster charging times, try out the BC430 that offers 30-minute charge time. The chargers run on 120V 60Hz only. The tool is equipped with charge condition indicator lights that shows the charge condition of the battery. Bosch Electronic Cell Protection (ECP) protects the battery against overcharging and overheating. When the battery is empty, a protective circuit automatically switches off the tool.

This drill/driver features a 3/8-inch single sleeve chuck that will accommodate most common applications. The keyless design allows for quick and easy bit changes.
The DC motor delivers 265 in-lbs of Max torque. The drill also comes with 20 clutch settings which is handy when using it in screwdriver mode. This prevents screw stripping and helps you avoid damage to materials. Output torque will increase as the clutch ring is rotated from 1 to 19. You can lock up the clutch when dealing with heavy duty work.

The Bosch PS31 is equipped with a variable speed trigger switch. The more you squeeze the trigger, the higher the RPM. Two separate gear ranges are available. The low gear (0-350 RPM) provides high torque for driving screws or making larger holes. The high gear (0-1,300 RPM) is intended for drilling lighter work. A slide switch or trigger lets you select high or low speed.

To decrease the likelihood of injury caused by a spinning bit, the drill also incorporates a brake system that will stop the chuck quickly as soon as the trigger is released. This will also be useful in the repetitive driving and removal of screws. The tool is also equipped with an automatic locking system that comes in handy when higher turning torque is needed. When the trigger switch is released the bit will be locked in one position. You can then tighten or loosen the nut or screw by rotating the tool by hand.

Another feature that you may find useful on this battery-operated drill is the built-in LED work light that allows for easier drilling/driving in low light or dark areas. It turns on automatically when the switch is activated. To reduce fatigue a soft, rubberized grip is incorporated into the drilling system. The Bosch tool is eligible for the ProVantage Protection Plan which means there is a tool replacement guarantee during the first year after purchase. The protection plan also extends coverage against defects for 2 additional years. The battery will be under warranty for 2 years.

The Bosch PS31-2A 12-Volt Max is one of the most popular drill/driver kits at Amazon.com. The product has a strong 4.5/5 star rating at this time of writing which means the majority of customers absolutely adore it. There are a few complaints about chuck wobble. However, not a lot of the reviewers have reported this issue. The majority of Amazon reviewers have keenly expressed their appreciation for the overall performance and design of the drill.

Many reviewers have found that the drill has plenty of power for the size. The compact, lightweight design makes it very easy to use for small driving jobs like unscrewing door hinges or installing tv mounts. One customer commented that the higher speed is not particularly fast for drilling in wood. Some 12V models such as Skil 2414-02, Milwaukee 2410-22, and DeWalt DCD710s2 offer 1,500 Max RPM. However, they are also heavier.

Customers have also found that the battery lasts a good time. They also like the fact that it comes with two batteries and a fast-charging system. Customers have also praised the drill for a number of its different features. The two speed settings, battery indicator lights, trigger grip speed control, keyless chuck, and torque limiter make it appeal to many people. The LED light has also proven to be a nice addition.

The Bosch PS31 12-volt drill/driver will not meet everyone’s needs. But if you are in the market for a small, light, and relatively powerful cordless drill, then based on the customer feedback you will be happy with this product. It is not a 120V corded drill but for most jobs around the house you do not need a heavy duty unit.
