The Makita BJV180 is a 18V LXT Lithium-Ion Cordless Jig Saw Kit. It has 4-Pole position cut settings (3 Orbital and 1 Straight) for fast and efficient cutting in all applications. The Makita BJV180s large variable speed trigger allows for total cutting control (0-2600 SPM). LXT Lithium-Ion provides longer run time, 5x lower self-discharge (for use any time) and 16 firm holding contact terminals (for constant high power). The 25-minute rapid optimum charger on the Makita BJV180 communicates with the battery throughout the charging process using the built inch chip in the battery and built inch CPU chip in the charger. This chip helps to actively control current, voltage and temperature to optimize battery life on the Makita BJV180.
