Bosch unveils PS31 Ultra-Compact Drill/Driver

June 7, 2010 – Building on the launch earlier this year of the re-engineered Bosch PS21 Pocket Driver, Bosch Power Tools & Accessories continues the introduction of its upgraded lithium-ion-powered 12V Max lineup with the unveiling of the  PS31 2-Speed Ultra-Compact Drill/Driver.

The new PS31 boasts both the shortest height (7”) and the shortest head length (7.04”) of any standard-chuck drill/driver. Bosch also says that the PS31 also comes in as the lightest tool in its class at 2.1 pounds.

According to the company 3/8” single sleeve, three-jawed chuck offers users the versatility to accomplish 90 percent of the most common drilling and driving applications and makes bit changes simple and quick. The two-speed drive train lets users quickly choose between high-torque (0-350 rpm) or high-speed (0-1,300 rpm) operation. And when it comes to speed, Bosch’s PS31 drills more than two times faster than other tools in its class.

Bosch also engineered the PS31 to deliver outstanding control in multiple applications. The 20+1 clutch and sensitive variable speed trigger enable users to precisely dial in their preferences to match the specific task at hand. A built-in motor brake enables exact serial screw driving, and a bright LED light illuminates the dark work spaces commonly encountered by this type of tool. The optimized soft-grip handle further enhances user control by reducing fatigue and offering a secure grip.

As with the PS21 Pocket Driver, the enhancements in power-to-size ratio are due, in large part, to an upgrade to second-generation cells within Bosch’s 12V Max lithium-ion battery pack and an upgrade from analog to digital electronics. These changes enabled Bosch to optimize the tool’s performance and improve on what was already the industry’s best ultra-compact battery system, in terms of both charge life and battery life, and bolster cold weather performance. The move to digital electronics also enabled Bosch to integrate its own Electronic Cell and Motor Protection System. The system protects both tool and battery from overloading, overheating and deep discharging, the three most common causes of cordless power tool and battery failure. Another new feature is an easy-to-read “fuel gauge,” which enables easier battery management for maximized productivity.

Bosch’s PS31 Two-Speed Drill/Driver comes with two batteries, a 30-minute charger and a sturdy soft-side case. The PS31 is covered by Bosch’s cordless tool warranty and is now available through authorized retailers nationwide. For more information, please visit www.boschtools.com or call 877-BOSCH-99.
