Question: I dont see one is there pilot bits with them ? purchased some from Lowes and tere wasn't
Document: I bought these to drill some difficult holes in granite. Like most such bits, they have no built-in pilot hole dril, so I drilled a hole the same size in a piece of scarp lumber, and then clamped the scrap in place to use as a guide. I let my garden hose dribble into the hole while drilling, and the job was done in minutes. I can see no appreciable wear on the bit I used, but it was only two holes. so I cannot comment in longevity.
Zipped right through the tiles.Glad I purchased it.I would recomend this product to any one that needs to cut holes in tile.
I needed to cut holes in porcelin tile and these hole saws worked perfectly. I made templates in plywood to keep the hole saws in place and used water to keep them cool. You must do this as there are no pilot bits included with these saws.
I don't need a hole saw to do 100 cuts. With that said I think you will get a good number of holes out of one of these saw blades as long as you keep it cool while drilling. This kit provided me with all the sizes I needed and more. If I had purchased the nice $30 ones individually I would have spent a lot more money than what this kit cost. I would purchase this again if I had to do it over.
I own a plumbing co. I have to drill holes for various jobs, a surface that used to give me trouble was porcelain tile. I bought these with low expectations because "you get what you pay for". To my surprise the bits worked very well. drilling through ceramic tile is like drilling through sheet rock. the bits don't have a pilot bit, but neither does the professional grade bits (core drilling bits).
The small bits that are included in this kit are utilized for one use only I have not been able to figure out how to get the tile plug out of the center. : All they work well in the larger sizes, you must use water when drilling to keep the bits in good condition. But would not recommend this set for the smaller sizes
I bought this hole saw set because it was an unbelievable price and I trusted the reviews. I was not disappointed. One name brand professional bit can easily cost what this entire set costs! My first test was to cut a hole in a granite kitchen counter top. It did so flawlessly.As another reviewer wrote, the hole saws do not come w/centering bits (some of the bits are too small for centering bits anyway).
I was disappointed that these hole saws do not utilize a pilot bit. They do however get the job done when used with a guide jig or drill press to keep them aligned.
I used the drills to make a hole in Travertine tiles and used a V shaped board to help center the drill, since it does not have a pilot drill. It worked great, better than what I had expected.
I bought this set because I needed one drill, but the price was so good, I couldn't resist the package. The one I needed worked perfectly, so I am very happy with my purchase.
