cavity acces tool
« on: November 11, 2011, 06:21 PM »
has any one used one of these.
link
its a hole saw with a collar on it that creates a rebate(rabit to the us folk). a metal disk then sits in thet rebate and closes off the hole again. you can get expanded metal disks so that you can use it on plaster board . i was thinking of using it for inspection holes before comitting too much, with this i can easily patch the hole

 what do you think of it , or has anyone out there got one

Sorry Alan, but that link only goes to the home page.  BTW the difference here between the animal and the wood joint is either an 'i' or an 'e'.  We were just bold enough to correct the King's English.  [tongue]

I think that this might be what Alan was referring to:  Cavity Access

That  looks pretty handy. Do they make them in  other sizes? I am thinking a smaller one would be good.

i havent seen one. not sure what youd want a smaller one for. you could create the same result on a smaller scale with a 2 forsner bits , a larger one to create a rebate and smaller one for the hole.

i was thinking of this but thought it wouldnt work great on plaster board and larger forsner bits are dear.
if anyone has a scourse for larger dirt cheap forsner bits (doesnt matter if they are crap as its only for plaster board.


it doesnt seem anyone has one of these cutters so i might review it when i get one

Is the idea of this to put in a camera or would you use it to do some sort of "flying splice"? If the latter, Really?

Tom,

I believe this is a similar implementation to the method of doing a drywall patch with the paper face being wider than the backside of the patch to make blending easier once installed over a hole.

I guess I was thrown off by the two Romex ends in the product page.

just thought id do an update and little review.
i bought one of these.

you get a case , the hole saw, arbor,rebating collar, waste removal tool ,10 solid disks, and 5 mesh disks
44321-0
44323-1
i put it in my drill and drilled a hole in a waste bit of ply . it worked good. the hole saw cut through fast but the collar was a bit violent as it started cutting. i think the carbite teeth could be sharper.
44359-2
44321-3

it created a hole that was a bigger than i expected as the metal disk had a few mm play around it (easing fixed , as i will get disks cut out rather than pay high prices for them)

44323-4
44359-5
it was also slightly proud of the surface in places so i used a chisel to take down the high spots.maybe it would work better on chipboard rather than shuttering ply.

i havent tryed it on plaster board yet but it should work ok.

44321-6

my verdict isnt great. its slow and violent on ply , expensive (holesaw and rebating bit would do the same thing cheaper, althow not on plasterboard).
its only saving grace will be (i hope [scared] [eek]) on plaster board where it will make fixing holes easier. as this is all i realy wanted it for it will be a good purchase but wouldnt be for floor use only

44323-7
44359-8
44321-9
44323-10
44359-11
44321-12
