The Cat® DX12K 18V 1 for all Cordless hammer drill and impact driver combo kit with two batteries features two powerful tools bundled together to take on tough pro-grade drilling and driving applications. 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 RPM 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 1/4″ hex drive to reliably grip and quickly switch out various bit sizes. 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 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.
