Another Great Tool from Makita
I have the 1/4 in Driver and the 1/2 in driver. Awesome drivers, Lithium Ion gets the job done with power to spare.

compact Power
An awesome tool. I use it to drive lag screws, especially the long 3/8" ones that the 1/4" impact driver can't quite handle. And it's incredibly useful for using on bolts, particular stubborn nuts or in confined spaces. No easier way to stitch two steel framed flats together on the top of a ladder than with this thing. I even got the 1/4" hex adapter and drive screws when I don't have another driver handy; the trigger control is good enough to drive even 1/2" long wood screws without over-torquing.

Best tool I own would buy another.
I dropped mine from 20 feet off a crane and hit concrete floor the battery flew off. I was sure it was history, put the battery back on and it never missed a beat. Best battery impact ever.MG

Great Makita product
I am an automotive technician and use this impact wrench to quickly loosen big bolts. This impact produces way more torque than any other battery powered one I've owned (including my last Makita one). I have yet to come across the bolt that overpowers this tool. My pneumatic impact gets alot less use now. This tool is relatively compact, it operates easily in tight spaces. The Li batteries this uses are pretty great too, I almost never have to charge them.

Great Driver BTW251Z
Got it with special Makita $25 discount. CPO was the only site that offered it with this model. Wanted this one since its made in Japan, the newer replacement model is Chinese. No issues with product.

Great gun for the price
We use the product every day to disassemble and reassemble forms it works like a champ. I wouldn't reccomend it where high torque is needed to remove rusted nuts or bolts.

The Makita Standard Warranty applies to both new and factory-reconditioned Makita tools. Every Makita tool is thoroughly inspected and tested before leaving the factory. If you are not satisfied with any Makita tool within 30 days of purchase, return it and Makita will provide a replacement or refund. Each Makita tool is warranted to be free of defects from workmanship and materials for the period of ONE YEAR from the date of original purchase. Should any trouble develop during this one-year period, return the COMPLETE tool, freight prepaid, to one of Makita's Factory or Authorized Service Centers.

Each NEW Makita Lithium‐Ion Power Tool, Battery and Charger is warranted to be free of defects from workmanship and materials for the period of THREE YEARS from the date of original purchase

If inspection shows the trouble is caused by defective workmanship or material, Makita will repair (or at its option, replace without charge).

This Warranty does not apply where:
  • Repairs have been made or attempted by others
  • Repairs are required because of normal wear and tear
  • The tool has been abused, misused or improperly maintained
  • Alterations have been made to the tool
In no event shall Makita be liable for any indirect, incidental or consequential damages from the sale or use of the product. This disclaimer applies to both during and after the term of this warranty.
