Questions & Answers


Can the saw cut granite with out a problem?

Asked by Dante004 August 4, 2020

Thank you for your question. No, the 4100NH 4-3/8" Masonry Saw is not intended for granite cutting. Please see the GA4030 4" Angle Grinder with A-94580 4" Diamond Blade, Turbo, Hard Material.

can this be a wet saw as well to prevent dust while cutting?

Asked by seannn November 28, 2019

I believe I recall the instructions said NOT to use as a wet saw. Please use a dust mask as it creates a lot of dust.

it is a wet saw?

Asked by Miguelon December 1, 2017

No. First cut I did, I did pour water on it, but if you don't mind the dust thrown up, don't need water. I put on a mask so I wouldn't have to breath in the dust. I was surprised how easily it cut through the blocks.

Does this one come with water hose connection?

Asked by Daniel September 29, 2017


Is this a 9.6 amps or 12 amps, the data plate in photo reads 9.6 amp? which one is true?

Asked by Daniel September 20, 2017

I just looked at my new one, and it is 9,6 amp. You will not run out of power. If you are, you are cutting both too deep, and pushing it too fast.

Can this cut patio pavers?

Asked by Donald August 25, 2017

yes - that is what I used it for.

what the depth on the cut

Asked by smithy June 17, 2017

I just measured one of mine at 1-1/4" maximum depth. I need to interject here though that I rarely cut all of the way through anything. Thinks like pavers, I cut/notch about 3/8 deep, (never measured), and snap them. Sure saves on blades, and is MUCH faster.

Is this appropriate to use to cut granite?

Asked by melanie April 28, 2017

yes it will cut granite

So, can't quite figure this one out. Just what is the difference between the Makita 4100NH, and ...

Asked by HomeownersHandyman January 11, 2017

I just ordered from Home Depot, and received the The 4100NH1. It came with one and only one blade. I called the Makita customer service phone number, then confirmed the The 4100NH is the exat same saw, but does NOT come with a blade, while the The 4100NH1 comes with one (1) Makita general purpose masonry blade, hence the number 1 in their model number.

Does it makes a lot of dust when you're cutting the tiles ?

Asked by Choco January 5, 2017

It makes a lot of dust. Make sure you have a dust mask and safety glasses on hand. I had to stop cutting to allow the dust to dissipate so I could see what I was cutting.

Good saw. The only complaint I have is that most of the concrete tiles I cut had to be marked and cut on both sides because the blade wouldn't cut all the way through.

It cut the concrete pavers well that we used for a new walkway. So much dust was produced that another worker was needed to spray water on the stone in order to see the cut lines and to control the dust.
