Question: Hi i was trying to used this blade on my 7 inch chicago electric bridge tile saw the saw keeps cutting out once the blade ii on the saw (whats wrong
Answer: Yes use plenty of water as usual
Question: What is the return policy
Answer: Back in the '70's a bottle cutter was the new hot arts and crafts item. It used a cheep class cutter attached to a pivot point. Once you scored the outside, you used a thick wire in a "S" curve to tap on the cut line until a crack stars and progressed all the way around. It made a nice sharp cut albeit too sharp. I think you can still find these tools on craft sites."

Question: How thin..what is the kerf..of the "super thin" goyonder 4.5 " tile blade

Question: Will this work for 1-1/8" Travertine pavers

Answer: No! Just at the wet saw!

User questions & answers

Question: Can this cut through a concrete slab
Answer: Yes, It can cut through the concrete slab easily.
Question: Will this blade cut through roof tile that is approximately 1/2” thick
Answer: Yes it will.like a hot knife cutting through butter. Get a hydro sponge same kind of sponge tile setters use.get some water on the sponge while your cutting let spong touch the side of the blade as your cutting.What this does is keeps the blade free of the fine dust and will also prevent small chipping of your roof tile..you will be impressed on how well these blades cut..make sure you use the sponge.if u don't what happens is the diamonds on the blade will get clogged up with fine dust and won't cut near as clean. Hope this info helps
Question: will this cut glass
Answer: This is not worth buying. The cutting edge is dangerous, as it separates when cutting
Question: The Rubi blades of similar design are not designed to cut a radius according to the distributor I feel with. Are these
Answer: The blue blades suck, the edge was chipping off after like4 or 5 cuts. Don’t waste your money. I bought 6 , still have 5. They are dangerous, not worth getting hurt. The red ones are awesome. Buy those Jerry
