The Bosch JSH180 lithium-ion 18-Volt jig saw is compact and lightweight. Its T-shank blade change system allows the user to insert the blade just without the need for any tools, and when it's time for a blade change, a turn of knob ejects the blade, so there is no need to touch a hot blade. This jig saw also features an always-on blower and integrated LED light for enhanced visibility in the cutting area. The sophisticated electronics package includes Electronic Motor Protection (EMP), which protects the motor against overload and ensures a long lifetime and the Electronic Cell Protection (ECP) protects the battery (sold separately) against overload, overheating and deep discharge. Battery and charger sold separately.
