Makita 18V Brushless Angle Grinder Kit – #THD-ProSpective


  The X2 series of Tools has been an awesome addition to the LXT line up. Makita is extracting astounding power from two 18v batteries. Some frown on the idea but I think it’s genius. One battery system for the full range of tools. Tools from sub compact to compact, regular size and oversized heavy-duty Tools can all run on 18v batteries. 

  Makita is almost always a front-runner when it comes to building powerful professional corded or cordless tools that will hold up to the job site. When they brought the X2 line out they were looking at the heavy-duty corded Tools that had not been matched by cordless Tools. Tools like SDS plus and SDS Max rotary hammers, the Skilsaw wormdrive and full size 10” sliding compound miter saws. 

  One of the newest tools in the X2 lineup is the full size 7” brushless grinder. This thing is a monster. It’s one of the biggest handheld tools out there.  We love the 4 1/2” grinders that have come out in the last few years. The performance is very close to a 6 amp corded grinder.  They will always be the most popular choice because they are so handy and can be used for so many applications. A 7” or 9” grinder is a whole other proposition and really requires some marvelous engineering. This size of grinder always has a 15 amp heavy-duty motor when corded. That is normally an 1800 watt plus combination. To get that kind of power out of 18v batteries is quite a feat. 

   It was no doubt a tough job to develop and build these grinders but wow the results are spectacular! From the first time you squeeze the trigger you can feel the kick of this beast. This thing was made to work. Welders, tile setters, masonry contractors, concrete surfacers, and others will benefit from this heavy-duty cordless solution. 

  We have mostly used it for concrete surface grinding to prepare for tile installation. Used with a dust shroud and the VC4710 dust extractor the results were excellent. Plenty of power in smaller areas like bathrooms and not a hint of silica dust in the air. Depending on how hard we push we can get anywhere from 10-20 minutes of run time with 6.0 amp hour batteries. That won’t give you all day results  on one charge but with 2 sets of batteries and a fast charger you should be good to go without a ton of downtime. 

  I’m not a welder but we do a fair bit of it in our shop.  My son is certified and we found the XG to be plenty powerful for pre grinding as well as cleaning up my errant welds.  A grinder is not the ideal tool for cutting steel but the XAG12 does pretty well with abrasive cut off wheels.  I don’t find much difference between it and my corded grinders.  Other than run time. 

   Cutting concrete is also a possibility with the 7” but the 9” makes more sense since it is the same tool with a lower RPM and a larger shroud to run the 9” blade giving a deeper cut.


  • Electric brake stops the grinding or cut-off wheel in 4.5 seconds or less for maximum productivity.
  •  Electronic torque control turns the motor off if rotation of the wheel is suddenly forced to stop.
  • Automatic speed change technology adjusts speed and torque during operation for optimum performance.
  • Vibration absorbing back handle is isolated from the motor housing effectively reducing vibration to the operator’s hands.
  • Rear handle paddle switch with no lock-on feature.
  • Efficient BL brushless motor is electronically controlled to optimize battery energy use for up to 50% longer run time per charge.
