User questions & answers

Question:	Will this cut steel
Answer:	That depends on thickness of wire shelving, these are only hand cutters, so they should not require a lot of strength, but again it depends on thickness of shelving you are cutting.
Question:	Can I use this to drill glass for light fixtures
Answer:	It depends on the size of the padlock. At the widest point the bolt cutter jaw opens to approx. 5/8" The manufacturer states that it is capable of cutting 7/16" soft to medium hard materials (chain) and 5/16" of hard materials (bolt). I hope this answers your question. Best
Question:	I make a lot of holes in wood with a 4" hole saw. I'm looking for something that will last longer. Will this work on wood
Answer:	Yes it will cut wire shelving
Question:	I just ordered this and i dont understand why it dont have a place to put the center drill bit
Answer:	New ones are usually really stiff. Lube them a little and pull on them hard. If they won't move you can try loosening the bolts and see if some got over tightened. Should not be stuck badly.

User questions & answers

Question:	will this be out of shape when hot
Answer:	3/16
Question:	Will this suit for drilling the fiberglass ?I afraid it will effect the perfect surface
Answer:	Hi Clinton. This is a standard-size, screw-on hose nozzle. It cannot be used to turn on/off water flow. It simply concentrates the water flow into a narrow stream, thereby increasing its power and reach. So, for example, you might use it to "power-wash" dirty siding on a house. --Tom
Question:	Do they run ture
Answer:	No !! U need to add off/on vave
Question:	What the best sfm for cutting glass? i understand the rpm will be different for each drill size
Answer:	This pottery tools set have a nice carton pack.

User questions & answers

Question:	Can this be used to cut acrylic
Answer:	It'll probably "work" but I doubt you'll like the results. It'll be slower going, and going thru anything much more than 3/4 inch would not work. It's pretty inexpensive, so you could give it a shot and not be out much, but there's better tools for that job. The metal is not the hardest and I bent the center pin on one stone cut, got sloppy, so this is probably not an improvement over whatever you're using now.
Question:	Does this work on Gel-coat/Fiberglass like in a boat
Answer:	You have to open up the "chuck" on the drill (where you put the drill bit) almost as far as it will go, and insert the saw's "peg" into the opening. Then tighten the chuck. Remember, to use a slow speed on the drill.

User questions & answers

Question:	Can this drill any more than 1 inch? Need maybe 1-1/8" to get thru some granite
Answer:	I could not find the answer on the Drilax.com website. The product worked for us- we drilled 2 holes in the granite counter
Question:	Will this drill make a hole in a cast iron bathtub
Answer:	I would use a hole saw for wood after drilling through the granite. Wood will embed itself into the diamond grit rendering it useless!
Question:	if i drill slow and keep the bit wet how many holes should this bit drill in 3/16 glass before being worn out
Answer:	SLOW...50 to 100 worked best on my tile. For horizontal surfaces, make a dam out of plumbers putty and keep the bit submerged. These are the best diamond bits I've ever used.
Question:	Will this work on a curved surface, to drill a hole in the side of a ceramic or clay jug
Answer:	Recommend use of water so bit doesn’t heat up, dull fast and possibly damage the granite. Not sure why you want to drill from the bottom, as that could damage top side. Recommend you create a wood template as a guide and drill from top. That would make use of water easier.

User questions & answers

Question:	how long to [cordless] drill 1 in hole, 1/8 in glass fish tank? or should I NOT drill
Answer:	Do you mean drilling thru aquarium glass? I would assume so - I use it to cut thru all kinds of glass.
Question:	Can they be used with a Dremel
Answer:	no glass surface does not need to be flat ,just start drilling at an angle
Question:	How deep are these? That is, what's the depth they can fit over
Answer:	It is designed to cut steel but if you had to it would probably handle 1/8 inch or less. If you are thinking of buying it for that purpose, get a hss metal hole saw instead.
Question:	Does the 40mm have a 1/4” shaft
Answer:	Yes. I drilled ceramic and marble tile. Just a suggestion you should look at a drill guide and glass cutting oil. The instructions say tilt the bit to start the hole but the bit will walk so the guide stabilizes the bit on the glass and makes a much cleaner cut.
