Questions & Answers
10Questions37Answers
does it come with 5/8 arbor adapter?
Asked by April 8, 20186
AnswersMr. Makita is wrong. The locking nuts are made for 5/8" arbor discs, so no adapter needed. As a side note, all 4-1/2" discs I have seen use a 7/8" arbor.

June 23, 2019
They really screwed up the on-off switch compared to the previous N9514B model I had. This switch is a rocker that you "lock in" by pushing down on the top after you slid it forward. It is incredibly sensitive so that any time you grasp it near the top of the handle it will go off. Very annoying especially when you are 20' up on a ladder!
The old model was a slider that locked front and back. It also had walls built up on both sides so your hand would not touch the switch when you grasped around it. I'm forced now to jam some thin cardboard under the rocker to keep it on.
Once on it works just fine, a little bit heavier, 1 amp more power and all old 4" discs and my depressed rubber pad kit still fit.

March 7, 2018
Could have bought online around same price and had delivered to my door but wanted to look at it before buying. I went to H.D. and picked it up, checked it out. I have 2 of the older 4" Makita grinders (2002 & 2005). I have ran them hard many times. They had straight cut gears and over the years have really got sloppy and noisy. BUT they have never quit running. I took one apart and greased and it helped noise some but still it was wore out. I bought the new Makita and tried it out this morning. It works great and way quieter. Thank Makita for making a good 4" grinder. I have 4.5", 5", 7" grinders also but these 4" ones are light and small to work in tighter quarters.
I will buy another soon.
older versions of this model did not hold up for long
December 16, 2012
I have owned 2 older versions of this same model, and either the commutator bearing froze or the armature burnt out and the arcing melts the case. And I use compressed air to clean out the dust after each use as recommended. Trouble is MAkita has the weakest 1 year warranty of the bunch, and that is about how long this model held up. Other trouble is MAkita has one of the only 3/8 " arbor grinders out there and I still have a large selection of discs and wheels to fit this size. Rock and HArd place I am between.

The grinder is really good, but you need to get a Cyclone Mesh Rim Diamond Blade for Porcelain, than its an every day tool. Works like cutting butter with a sharp knife. Works on porcelain, brick, plaster, plywood, wood!
