Best-in-Class Power & Run Time From Intelligent Rotary Hammers
Milwaukee Tool has expanded its M12 FUEL™ line of power tools with the new M12 FUEL™ 5/8” SDS Plus Rotary Hammer for drilling holes of up to 5/8” in concrete and masonry. According to the company, this electro-pneumatic unit not only offers 75% more speed and the largest SDS Plus bit capacity in its class, at only 10” long and 3.9 lbs, it performs comparably to much larger tools at a fraction of the size and weight. Designed, engineered and built by Milwaukee Tool, the product’s 12-volt brushless POWERSTATE™ motor provides up to 6200 BPM and up to 900 RPM. New Milwaukee REDLITHIUM™ XC4.0 batteries allow up to 2X more run-time, 20% more power and 2X more recharges than standard Lithium-Ion batteries, and function in extreme conditions (below 0 F/-18 C) with fade-free power. An advanced REDLINK PLUS™ Intelligence hardware and software system ensures continuous full-circle communication between tool, battery and charger to optimize performance and overload protection.
