Makita's BJR181 cordless reciprocating saw offers craftsmen the best of two worlds with ridiculous power and a surprisingly lightweight, compact design. Utilizing lithium-ion battery technology and an optimum battery charging system the tool has vastly extended work-time (with 2x as many charge cycles). Makita is known for building some of the highest quality motors in the industry, and the BJR181's high torque motor, delivering 50% faster cutting with a 1-1/8" stroke and 2,900 SPM, never fails to impress. The tool weighs merely 8.1 lbs and with an ergonomic design the saw is well balanced and delivers always even pressure. The saw additionally has two built-in L.E.D. lights to keep your work areas illuminated - even in tight spaces - and with fast one-handed, tool-less blade changes and shoe adjustments, the saw is simple to use. Also, for simple serviceability this recipro saw has externally accessible brushes ensuring the inevitable brush replacements are a far less frustrating process. Keeping better tabs on your brushes also ensures your motor will lead a healthier, stronger, and longer life. Additionally, being cordless, this reciprocating saw has superior portability, the strength of lithium ion technology, and the big power to saw through, well, anything.
