Can you use it to cut small, thin tiles such as the one for a backsplash?


Short Answer: No.

This saw specializes in cutting masonry material like outdoor stone blocks, bricks, pavers, etc. Cutting tile on this saw may result in chipped/broken tile when using an aggressive blade.

Is the blade that comes with this saw suitable for firebrick?

The included blade is an economy concrete block & paver blade. It will be able to cut firebrick, but Norton does offer higher quality diamond blades that may cut firebrick more quickly and effectively.

It appears that the hole in the Norton blade supplied is of smaller diameter than the arbor. There are three very small holes and scoring at the center of the blade. Am I supposed to press out the center of the blade?

These blades are commonly referred to as knock out blades. Yes you are to "knock" out the inside pieces and it will fit on this saw.

I understand the water kit comes separate, but do the lines connected to the guard come with the saw as pictured?

Yes, there are water tubes that have a gardena water hose attachment at the end. This will attach to any standard water hose. When that is not available, the water kit accessory should be used with the BBM307.

I've been in the masonry business 40 yrs this year. I bought a new Clipper Block Buster saw in 1983 and it's still running good to this day 34 yrs later. The only complaint I have is that it is very heavy but once it's on the job it's performance is very good to excellent.

Great saw at a great price!


I have four of these saws and they work great! Lightweight and very dependable. These will cut dense firebrick very well with the 14" blade that comes with the saw. Contractors Direct had the best pricing, item in stock and shipped out the very next day after I ordered! They also keep you posted with a tracking number so you'll know when to expect delivery. This is the second saw I've bought from them and will continue to use their service.



i received your order in no time at all after thinking it would take weeks. very happy with the saw and stand, thank you
