The Cat DX12K 18V Cordless Hammer Drill & Impact Driver Combo Kit with Two Batteries features two powerful tools bundled together to take on tough pro-grade drilling and driving applications. Built with High-Efficiency Brushless Motors, the cordless Hammer Drill and Impact Driver deliver 25% more power, 50% longer run time, and 10% longer life than brushed-motor alternatives. The Hammer Drill is supported by a durable 2-Speed All-Metal Gear Box to achieve no-load speeds up to 2,000 RPM for heavy duty applications. For added productivity, use the 18+2 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 18 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. The Impact Driver is built with a 3-Speed All-Metal Gear Box that’s capable of producing no-load speeds up to 2,000 RPM. And with variable speed functionality, it’s easy to maintain precise control over RPMs for both standard and heavy-duty driving applications. This impact driver packs a max impact rate of 3,600 BPM and max torque of 1,900 in/lbs. to drive into concrete, tile, stone, brick, and other masonry materials with ease. Rely on the ¼” hex drive to reliably grip and quickly switch out various bit sizes. To support extended work, both tools feature lightweight construction and feature a Textured Overmold Grip to reduce fatigue and improve control. Kit includes stackable, easy-transport Slide Lock case with innovative locking and durable construction to defend against dust, water, and impact damage. Power the Hammer Drill and Impact Driver with the included Cat® 1 For All batteries and charger. The battery platform is a rechargeable, interchangeable system that supports all tools within the expansive 18V cordless power tool line from Cat.
