RIDGID introduces the 18-Volt OCTANE MEGAMax Reciprocating Saw (Attachment Head Only). The OCTANE MEGAMax Reciprocating Saw (Attachment Head Only) features high performance brushless motors and advanced electronics that provide best-in-class power and intelligence. The MEGAMax Family is the industry's most powerful interchangeable tool system. This Reciprocating Saw Attachment Head, when paired with the MEGAMax Power Base (not included) and a RIDGID OCTANE battery (not included), is the industry's most powerful reciprocating saw. While being compatible with all RIDGID 18-volt batteries, OCTANE tools provide maximum performance when paired with OCTANE batteries (not included) in high demand applications. This means, under heavy loads, the tool talks to the battery to determine when to draw maximum power to the motor, allowing the tool to increase performance and finish the task. With registration, this tool is backed by the Industry's Only Lifetime Service Agreement: FREE Parts. FREE Service. For LIFE. The OCTANE MEGAMax Reciprocating Saw (Attachment Head Only) includes an operator's manual. The MEGAMax Power Base, batteries and chargers are sold separately.
