Makita's BTD141 (18v) cordless impact driver truly packs a wallop incorporating some new, innovative features and a maximum torque motor that delivers a huge 1,330 in/lbs of serious torque. Despite this big power the tool still maintains an efficient and compact size (weighing only 3.4 lbs); the impactor's ergonomic shape distributes pressure evenly throughout the tool for comfortable, easy control. A built-in LED light illuminates work spaces, and a high quality heat-hardened steel proprietary hammer and anvil significantly increase the tool's overall life and durability. The tool additionally has an electric brake for immediate stops which not only increases your safety, but also minimizes kickback, otherwise known as the enemy. Utilizing lithium ion battery technology and an exclusive charging system that optimizes battery life and produces more than twice as many cycles, the tool is powerful, durable and terribly efficient. Additionally, a slim, cordless design renders the tool mobile and maneuverable making it an ideal choice for the most industrial workers to the most average homeowner.
