This Bosch 12V Max Flexiclick 5-In-1 Drill/Driver System features an efficient EC Brushless motor for max runtime and upgraded power – 300 In. -Lbs. of torque. The GSR12V-300FC is designed for professionals who want a high-quality tool that redefines their limits to get the tough jobs done. At only 1. 2 Lbs. (tool only, not including battery) and a max speed of 1, 750 rpm, this robust drill/driver delivers the performance you expect in the size you want. It has two speed settings – a 0-460 rpm for high-power driving tasks and 0-1, 750 rpm for high-speed drilling. It starts with a magnetic bit holder for basic driving. The four attachments – a locking bit holder, a keyless chuck, an offset-angle and a right angle– each attach to the tool securely and easily with the One-Click interface. The right-angle attachment is for tight spaces, and it works with all three other adapters. The offset-angle attachment delivers precise screwdriving close to edges. Both of these attachments rotate to 16 positions without removing them. The locking bit holder attachment locks hex bits for high-torque drilling, while the keyless chuck provides locked-in drilling.
