Makita DTD157RTJ 18V Cordless Brushless Impact Driver (LXT-Series)

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
