The 2729-21 is a genuine product manufactured by Milwaukee Tool. It is a Deep Cut Band Saw which is part of Milwaukee's M18 Fuel collection. The M18 collection allows the user to use M18 lithium batteries that work in correspondence with all other Milwaukee Cordless Power Tools that utilize the M18 lithium battery. The M18 battery is charged using the Milwaukee Multi-Voltage Charger which will also charge M12 batteries as well. The Band Saw conveniently uses over 90 percent of the same parts as Milwaukee's Corded Deep Cut Band Saw. This Milwaukee Tool's greatest feature is its deep cutting area. It has the industry's largest cutting capacity, cutting pieces up to 5 inches by 5 inches. The adjustable shoe allows for less tool rotation when cutting material above 5 inches. This is the perfect tool for cutting fence posts on the go, as the traditional fence post is a wooden 4x4 (4 inches by 4 inches). The cordless band saw also utilizes Milwaukee's CPT (Constant Power Technology) which provides constant power for cutting speeds. Job Armor Technology is applied to this tool for optimal strength and protection for the tool while working in any place. The 2729-20 Band Saw kit also includes one M18 REDLithium XC 4.0 Extended Capacity Battery Pack (48-11-1840), one M18/M12 Multi-Voltage Charger (48-59-1812), one Blade and a Carrying Case. Five year tool warranty from Milwaukee Tool.
