Makita 6.35mm (1/4″) 40 N·m (1,240 in.lbs.) Cordless Impact Driver 18V LXT® Li-Ion [Bare Tool] DTD157Z

Features:
• Anti-bit wobbling structure
• Two ball bearings are used to securely hold the anvil for reduced bit wobbling
• Despite the internal design change for the rigidity, redesigned gear section makes the overall length 2 mm shorter than DTD155
• Compact body for easy screwdriving in narrow space
• 3-mode operation for A-mode / Hard mode / Soft mode for multiple applications
• A-mode feature helps eliminate “screw cam-out” and “cross threading” by driving at low speed until tightening begins
• Variable speed (0-1,300/0-3,000 RPM & 0-2,000/0-4,100 IPM) for a wide range of fastening applications
• BL motor is electronically controlled to optimize battery energy use for longer run time per charge
• BL motor eliminates carbon brushes, enabling the BL motor to run cooler and more efficiently for longer life
• BL motor efficiently uses energy to match torque and RPM to the changing demands of the application
• Compact and lightweight for reduced operator fatigue
• Ideal for working in tight spaces
• Best possible ergonomic handle for screwdriving applications
• Ergonomically designed handle with soft grip provides increased comfort
• Built-in twin LED light with preglow and afterglow functions illuminates the work area
• eXtreme Protection Technology (XPT) is engineered for improved dust and water resistance for operation in harsh conditions
• Convenient 6.35 mm (1/4″) hex chuck for quick bit changes
• Electric brake for maximum productivity
• Aluminum hammer case creates the impression of rigidity of the machine. Reversing switch is conveniently located. Durable, reversible belt clip convenient for temporary tool hanging
