This is my Makita TD171DB from Japan. I have enjoyed it a lot so far (1 month). I have had the makita xdt13 impact driver for almost a year now and love it so much that when i found out these existed i went and got one. The TD171D incudes the following 4 Speed modes: 1 -- [ 0-1100 rpm & 0-1100 ipm ] 2 -- [ 0-2100 rpm & 0-2600 ipm ] 3 -- [ 0-3200 rpm & 0-3600 ipm ] 4 -- [ 0-3600 rpm & 0-3800 ipm ] 1600 in/lbs max torque The 4 assist modes include: 1 for entering wood, this mode starts slow until it you get into the wood a thread or two then it ramps up and blasts her home, impacts and all.There are two assist modes for self tapping screws. T1 for tapping into thin sheet metal, this mode avoids over tightening and "stripping out" a fastener into thin meta. T2 tapping assist mode is for thick metal and starts with high rpm and no impacts to get the drilling started and then blasts her home with all the fixins'. The other assist mode is for tightening and loosening nuts on bolts and stops the nut just short of coming off of the threads so you don't shoot a nut across the shop. You can also scroll through the speed modes with the button located above the trigger where the LEDs' are located on other models. The lights can be turned into off mode on the control panel located at the base of the handle. The assist modes and speed modes can also be accessed on this control panel.This panel is also used with the new button to save an assist mode and a speed mode so that you can switch between modes while working with only the hand already operating the impact driver (i actually find this quite handy). An interesting feature is the rubber collar (idk what to call it) around the business end, just after the 1/4" hex drive, is glow in the dark. this driver also features dual bearings at the business end to mitigate bit wobble. The thing is tiny its smaller than my hand if I make a fist, like a lot smaller. The side mounted lights are an awesome feature, no more fastener shadow 98% of the time. I do electrical work in a variety of climates and conditions, these makitas put up with it really well so far.
