The M12 Fuel™ 1/2 in drill/driver takes 12 V cordless drill/drivers to the next level of performance and durability. This lightweight, versatile drill/driver provides up to 10X longer motor life, 2X more power and 4X more runtime. The POWERSTATE brushless motor outperforms all leading competitors with constant power output, yet runs cooler and quieter with no wearable components. REDLINK™ PLUS™ intelligence ensures optimized performance and protects your investment from overload, overheating and over-discharge. It can be used with the REDLITHIUM™ 2.0 compact battery pack and 4.0 extended capacity battery pack (sold separately), which deliver more work per charge and more work over pack life than the competitors, even in extreme conditions. The M12 FUEL drill/driver's on-board fuel gauge helps you monitor the charge precisely, so there's less downtime on the job and a built-in LED Light illuminates the work surface. An all metal ratcheting locking chuck provides maximum grip, bit retention and durability. A new contoured soft grip gives you ultimate comfort during prolonged use.
