The CAT® DX12 18V 1 for all 1/2 in. Cordless hammer drill with Brushless motor uses advanced technology and design to enhance power and performance for pro-grade drilling and driving projects. Built with a high-efficiency brushless motor, this cordless drill delivers 25% more power, 50% longer run time, and 10X longer life than brushed-motor drills. Supported by a durable 2-speed all-metal gear case, this hammer drill can take on both standard and heavy-duty applications: use the low-speed setting that reaches up to 500 RPM or the high-speed setting that achieves up to 2,000 RPM. For added productivity, use the 22+1+1 clutch to switch between drill and hammer mode. The hammer mode can achieve a max impact rate of 32,000 BPM to seamlessly drill or drive into concrete and masonry materials. Also use the clutch to adjust between 22 different torque levels up to a max torque of 600 in/lbs. to bore through any material. And with the 1/2″ all-metal ratcheting chuck, this hammer drill can keep a secure grip on larger bits-such as those designed for concrete or masonry. To support extended work, the cordless drill weighs only 4.2 lbs. and features a textured over mold grip that reduces fatigue and improves control. Includes stackable, easy-transport slide lock case with innovative locking and durable construction to defend against dust, water, and impact damage. Power the hammer with the included CAT® 1 for all batteries and charger. The 1 for all battery platform is a rechargeable, interchangeable system that supports all tools within the expansive 18V cordless power tool line from CAT®. For optimal performance, run time, and protection, choose the 5.0Ah graphene battery over lithium-ion options.
