Unveiled about a year ago, Bosch’s Multi-X is powered by a 12-volt lithium-ion battery and is one of two cordless multi-tools here. It uses the same Max Litheon™ battery platform as Bosch’s other Ultra Compact tools. Two batteries and a 30-minute charger come with it.
Weighing only 2.2 lbs., this machine has a compact barrel grip, appointed with soft overmolds Variable speed allows you to adjust it from 5,000 to 20,000 opm, to handle everything from slow metal cutting to high-speed sanding or polishing.
Bosch packages the Multi-X in two hard-cased kits. The Cutting Kit ($160 to $170 in 2010) comes with a hook-and-loop sanding plate, several grits of sandpaper and a plunge cutting blade for wood. A more expanded Carpenter Kit includes everything in the Cutting Kit plus three narrow plunge blades for wood and a semicircular segmented blade for wood, metal or drywall. This bigger kit sells for around $189 to $199.
Unique to both kits, Bosch provides a round adapter disk that covers its 12-pin attachment head. This enables the Multi-X to accept accessories from Fein and Dremel with their different mounting configurations. That way, you’ve got a wide range of blade options, including those Bosch doesn’t currently offer. Another nice little detail I like is an on-board “fuel gauge.” Just push a button to see instantly how much charge is left in the battery.
