Bosch PS42-02 12V Max EC Brushless 1/4" Hex Impact Driver Kit

The Bosch PS42-02 12V Max cordless impact driver kit supplies up to 975 in-lbs of rotational torque and 3,100 BPM for high-speed fastening and driving within confined cabinetry and electrical setups. Engineered with an ultra-short 5.5-inch head length and a 1.6-lb bare tool weight, this compact driver utilizes an EC Brushless motor and an all-metal gearbox with a 2-stage Performance Control System (0-1,200 / 0-2,600 RPM) to prevent fastener stripping. Featuring a 1/4-inch hex quick-release chuck, a 3-LED shadowless illumination ring, two 12V Max 2.0Ah lithium-ion batteries, a fast charger, and a canvas storage bag, it provides sustained runtime for electrical contractors, finish carpenters, and HVAC installers.

Best Used For:

  • Cabinetry and Concealed Hinge Installation: Driving hinge mounting hardware and drawer slide screws inside narrow 12-inch base cabinet interiors with a 5.5-inch head clearance.
  • Electrical Box and Conduit Strap Mounting: Fastening junction boxes, cable clips, and metal framing fasteners using 975 in-lbs of brushless driving torque without wrist fatigue.
  • HVAC Sheet Metal and Duct Assembly: Driving self-tapping sheet metal screws rapidly into overhead galvanized duct transitions utilizing the 2,600 RPM high-speed mode.

Key Performance & Safety Features

  • EC Brushless Motor Efficiency: Delivers extended motor lifespan, zero carbon brush maintenance, and up to 2x operational battery runtime compared to legacy brushed tools.
  • Ultra-Compact 5.5-Inch Head Length: Industry-leading front-to-back profile easily clears structural framing obstacles and fits into tight machinery enclosures.
  • Performance Control Speed Selection: Two electronic speed settings allow operators to toggle between low-speed precision fastening and high-speed driving up to 2,600 RPM.
  • Three-LED Shadowless Light Ring: Circular 360-degree LED cluster mounted around the chuck eliminates tool shadows to fully illuminate dark target fasteners.
  • Quick-Release 1/4-Inch Hex Drive: Secures standard 1/4-inch hex power bits and insert bit holders with rapid single-handed pull-to-insert engagement.
  • Rugged All-Metal Gearbox: Heavy-duty planetary gearing transfers high rotational force while dissipating heat under continuous industrial workloads.
