Heavy duty yet lightweight-that's the beauty of the RYOBI ONE+ HP 18V Compact Brushless 1/2 in. Drill/Driver. Measuring at only 6.4 in. in length, this tool is 30% more compact and 20% lighter weight than the brushed model, giving you better access to tight workspaces and overhead applications. It's also equipped with a brushless motor that delivers up to 400 in./lbs. of torque for maximum power when drilling and driving through tough materials. Other special features include a two-speed gearbox (0-450 and 0-1,700 RPM) and a 24-position clutch for maximum control while drilling and driving. The 1/2 in. single sleeve ratcheting chuck is custom designed with a unique knurling pattern to provide a durable grip for quick bit changes. Best of all, it is part of the RYOBI ONE+ System of over 175 cordless tools that all work on the same battery platform
