User questions & answers

Question:	is enrh3203 better than enrh
Answer:	It expands to 3" (or approximately 3.3" inside a 0.35" thickness). So if your phone is 3" or less in width, it will hold it. The bracket swivels, so the phone can be orientated in any desired position.
Question:	How wide is the chisel bit that comes with this drill
Answer:	I wouldn't even call it an installation....it just has two prongs that hold onto a vent louvre. If you want to remove it, just pull and it slips right off, but stays put when in use.
Question:	Can this drill be used with a smaller 3/16 sds plus bit
Answer:	Yes it fits iphone 4 and all manufacturers that my family uses.
Question:	what type oil should I use
Answer:	We are using it with a 7plus and it works great. Our case is not bulky.

User questions & answers

Question:	No torque rating? Does anyone know the torque rating or max hole saw size in wood and steel
Answer:	I don't know that I would use it for wood, though I guess you could. It can be set to drill, to jack hammer, or to drill and jackhammer combined. Also, don't know about torque, but I found it to be sufficient for all applications I've tried it in. It is surprisingly powerful and durable for a snall handheld unit.
Question:	Does this have a 3rd setting to drill w/o hammer option so can core drill
Answer:	It has 3 options: 1: drill without hammer, only spining, 2: drill with hammer, 3: hammer only for chisel. No spinning...
Question:	Does this unit have the option of variable positions for chisel bit
Answer:	Yes, it can lock in position either horizontally or vertically, as I have used it in both positions. It may lock in other angles, but I have not tried it in angles other than parallel or perpendicular to the handle. I also will mention that this unit has performed admirably and I have absolutely no regrets with my purchase. I was able to remove old tile (put down in the 1950's with thick-set. I found it works best at lower speeds and sharp angles of attack. Take your time and you won't work up any sweat, letting the tool do the work. Hope this helps.
Question:	How do you place the drill bit in the hammer drill, I have been working on this task for a few hours,it do not grip the bits at all
Answer:	This drill does require the special SDS carbide drill bits that have three slots in the shank. I pull the nose piece back and press a little on the bit and it will slip into the drill. I then rotate the bit to ensure that it is locked into place. The slots in the SDS drill bits allows then to transfer the drills hammer action to the drill point. With this drill only bits that are marked SDS Plus will work.

User questions & answers

Question:	would I be able to remove floor tile with this
Answer:	Ceramic tile I assume? This is a very powerful hammer drill. I use it to drill or bust thru all kinds of masonry products, poured concrete, blocks, brick, mortar etc.. It would have no problem with the tile, but you would have to be very careful not to damage the subfloor underneath, for tile typically some kind of cement board. This drill would easily punch thru that too. Check with a Home Improvement store or the Internet for a more appropriate tool/ technique. Otherwise I do endorse this product when used for the kinds of jobs designed for.
Question:	Is the case 100% plastic or is the silver part metallic
Answer:	Hello friend. The case is plastic and the silver part is aluminum
Question:	Is this strong enough to breakup the concrete walls of inground pool
Answer:	It possibly could be powerful enough, but it would surely take a long time. Better to rent a commercial tool for a job like this.
Question:	Hi sir, what is the difference between 'chisel' and 'hammer' functions? thanks
Answer:	The chisel doesn't rotate like a drill, but it still has hammer action.
