When the job takes your Makita tool into harsh conditions, Makita Extreme Protection Technology (XPT™) provides added protection. XPT™ is a series of integrated seals engineered to channel away dust and water for increased durability. Wherever the job takes you, Makita tools equipped with XPT™ are engineered for increased durability and longer tool life. Lasers are typically utilized in the early stages of construction, and measurement needs will vary based on application requirements. The Makita 12V max CXT® Lithium-Ion Self-Leveling Cross-Line Red Beam Laser (SK105DZ) gives the user a cordless solution for level, align, and plumb applications. Depending on ambient light in the working environment, the SK105DZ has a line visibility range up to 82' and is detectable up to 262’ with a Makita Laser Detector (sold separately). The SK105DZ has a bright 635 nm class II red laser with +/-1/8” at 33’ for best-in-class accuracy. The laser line fan length spans past the 90 degree position to provide 180 degree horizontal and 160 degree vertical lines for full reference line coverage. For increased efficiency, self-leveling line stability is achieved in up to 3 seconds for increased productivity. For longer run time, all 12V max CXT® cordless tools are also compatible with the 12V max CXT® Lithium-Ion 4.0Ah battery (BL1041B, sold separately). 12V max CXT® lithium-Ion batteries are engineered with a Battery Protection Circuit that protects against overloading, over-discharging and over-heating. It’s part of the expanding 12V max CXT® series, combining performance with superior ergonomics in a compact size. For users in the 18V LXT® battery platform, the SK105DZ has a power connector port that allows an 18V LXT® battery to be used with the Power Source Adapter (ADP05) and Adapter Cord (18V battery, adapter and cord sold separately).
