Bosch PS31-2A 12V Max 3/8-in Drill/Driver Kit review

The Bosch PS31-2A is the battery-included kit version of the PS31 12V Max drill/driver, not the separately listed PS31N bare-tool package. Bosch's exact US page lists two 2.0Ah batteries, a charger, two screwdriver bits and a carrying bag. The image on that page shows only one battery; the written Includes list is the source for the two-pack count. This is a desk-based assessment of Bosch's current listing and linked instructions, not a hands-on test.

What the kit and drill actually offer

The core tool is a plain drill/driver with a three-jaw, 3/8-inch keyless chuck. Bosch lists two no-load ranges, 0–350 and 0–1,300 rpm, plus 20+1 clutch settings and a maximum torque claim of 265 in-lb. Those figures describe the maker's published specifications, not independently measured loaded speed or fastening force. The two ranges provide a low-speed choice for controlled driving and a faster range for drilling; the adjustable trigger varies speed within the selected gear. An integrated LED is listed, while the exact US product page does not establish a brushless motor, so this review does not label it brushless.

The PS31 operating manual gives useful boundaries that a torque headline cannot: maximum recommended capacities are 3/4 inch in wood, 3/8 inch in mild metal and a 9/32-inch screw size. These are Bosch's material-specific manual limits, not a guarantee that every bit, wood species, fastener or work setup will perform the same way. The 3/8-inch chuck is a bit-shank opening limit; it does not mean the drill is rated to bore 3/8-inch holes in every material. There is no hammer-drilling mode documented in the reviewed product page or manual, and no masonry capacity is stated in the manual table.

Package identity matters

The PS31-2A package is a useful distinction for someone who needs the Bosch 12V Max tool and basic power equipment in the box: Bosch lists two 2.0Ah packs, one 12V Max charger, two screwdriver bits and a bag. Neither battery model number is named in that Includes list. Bosch's technical table identifies a BC330 60-minute charger, but the package list itself says only “12V Max charger”; check the printed charger label and exact carton if its model is important. The page's downloads also include a GAL12V20 charger manual, which is not proof that a GAL12V20 is the specific charger supplied in this kit.

PS31N is a separate PS31-family bare-tool listing. Its exact Bosch page lists the drill and two bits, and explicitly says that battery and charger are sold separately. Do not treat the PS31N's contents as the PS31-2A kit, or assume a marketplace listing's suffix from a similar blue-and-black product photo. The PS31-2A page also lists the HDC200 dust extraction/collection hood under compatible products; it is not among this kit's included items.

The image on Bosch's PS31-2A page presents the drill with a bag, charger and one visible battery. Bosch's written list says two batteries, so the photograph should not be used to count the pack contents. Weight also deserves caution: the product page highlights and technical table say 1.8 lb, while its further-information text says the drill weighs just over two pounds without reconciling the basis. The PS31N sibling page calls 1.8 lb a tool-only value, but that does not settle the exact kit page's inconsistency. This assessment leaves a comparable tool-only weight unassigned rather than treating either figure as resolved.

Fit, space and limitations

Bosch specifically states a 7-inch tool-head length for the PS31-2A. That is one inch above this site's inclusive 6-inch-or-less finder condition; it is not evidence that the drill cannot fit any particular location. The real envelope also depends on the chuck, bit, battery, hand position and approach angle. If a documented head dimension of 6 inches or less is essential, this model does not meet the published threshold. If compactness is only a preference, inspect the work area rather than treating a “compact” description or the overall kit image as a clearance guarantee.

The strongest case for this SKU is a buyer who values the Bosch 12V Max system and prefers to receive the listed pair of 2.0Ah packs, charger, bits and bag with a 3/8-inch drill/driver. It is a poor fit when the essential requirements are hammer action, a 1/2-inch bit shank or a head no longer than 6 inches. Before ordering, confirm the exact PS31-2A suffix, read the current manual for the material and bit, and check battery and charger model labels rather than assuming that every package sharing “PS31” has the same equipment. The manufacturer listing establishes the reference package, not seller stock, condition, runtime, ergonomics or tested performance.
