hole saws!

hi

1. faq says use "fine toothed" hole saws for making holes in metal cases for fans. home depot only has 'blu mol aggressor' brand/name hole saws in the sizes required... and the teeth dont really look 'fine' to me, and they dont say 'fine' anywhere... but i dont have any reference to compare to. are these 'fine' or not?

2. what size hole saws do you guys use for 80mm and 92mm fans respectively? i dont have them in front of me right now, but as i remember, the 3 inch hole saw was just a tiny bit too small for an 80mm fan, and the 3.25 was just a tiny bit too big. aesthetically, i prefer the 3 inch, but i am worried that blocking even a small part of the fan's aerodynamics would be a poor decision. also the 3.25 saw would leave holes on the sides of the fans... how would i plug those up to prevent dust from getting in? 🙁

ZippyDan, if you have a RotoZip (every good modder does), get their hole cutter attachment. I just cut a 3.75" hole in the top of my lian-li PC75 in about 2 minutes. I'm sure you could use a dremel to do the same thing. Dremel also has a hole cutting attachment. Of course my case material is aluminum. With steel, you'll have to go a bit slower. If you wanna see my case hole, email me for some pics @ stevennoland0146@msn.com.
 
i saw smaller teeth on some smaller hole saws 😛

i am not a good modder, i use a drill 😛

it is steel but i am going through flimsy side door

and where did you find 3 1/8th hole saws? 🙁

You can check with local tool suppliers. A DeWalt store might have some, for instance. I found an online retailer with some Simmonds ones: link

A piece of advice from Doctor mechBgon: wear eye protection! Eyes don't grow back. 😉 Also fasten down the panel very securely with clamps and wooden blocks; you don't want the holesaw siezing and spinning that thing at you. 😛
 
quick question for you guys... how many TPI would you suggest for cutting various materials?

i.e. plexiglass, steel, alum, copper, wood.
(I just listed these because they're the most common to work with in the modding community, with the exception of wood, which is commonplace anyways)
 
zippy,
I also went to home depot hoping to score some hole cuting bits but no luck on finding ones with fine teeth. The ones they had look like T Rex teeth......
I'm going to look around the internet to see if I can find some fine tooth ones....I'll let ya know if I find any...

found these and requested more information on larger ones with fine teeth..
 
i used the one from home depot with the big teeth. I thought it was 76mm but it could have been 79mm. Either way, it worked great. Just cut from the inside out so you don't have to worry about scratching the outside in case the bit hops. Once you put on a grill, depending on the type of grill you use, it will cover any imperfections you may have done. I used these grills for my black case: grill
 
screw holesaw teeth size. you're just better off getting some bimetal holesaw. dont bother with fine tooth or not. it's not worth the time looking.

the 3 inch hole saw will cut slightly larger than 3 inches. after deburring and cleaning the edge, you'd have that 3 1/8 or 3 1/16. you want the hole to be slightly smaller than the size of the impaler on the fan. btw, the extreme edge of the impaler is relatively useless.

use the lowest RPM possible, and increase it if you have to... and use a lubricant.

repeated for emphasis =D

it's cheaper to just get a smaller holesaw, and cut a clover or something.
 
I also suggest using a crap piece of wood to make a jig. Cut a hole in it with the hole size you intend to use on the case.. then clamp the wood down with the hole directly over where you wish the hole to go in the case... this will prevent the bit from bouncing. I had to do this to install a dead lock in my side door of my house, otherwise I would have scratched the hell out of the door.
