Diamond hole saw

[pirate]

Just thought I would share that Rona has a new line called Eco that has diamond hole saw for quite cheep. I thought ( poor memory) that a 1.5" was close to 30$ but so far the only one that has them is the one in the NE of Calgary. But currently they are out more comming in according to the guy there.

remember you get what you paid for-if it is for a one time use then no problem-but if you are going to be doing multiple cuts i would go for a more expensive one-you also have to look and see if it isn't warped-i bought a dewalt (really crappy company now)6 " hole saw and it was off center by 3/8 of an inch.at the same time i bought a set of diamond hole saws at summit tools(8 different sizes) for around $80 and they have worked out fine-but i wouldn't use them more than 4 times before replacement.the average diamond holesaw runs about $80

I have to disagree of this, I bought two hole saws on Ebay, shipped for 25 dollars. They were "cheap" but very well built. I used them to cut four holes each and to be honest they could probably do 2-3 more each. Paying more isn't alway going to give you better quality.

I have gotten a number of out holes out of the "cheapies" so they aren't that bad.

Garry, if you are looking for hole saws check out mops.ca. I think they are the same as the ones BRS carries but will cost you less.

Thanks mate.

My workplace sells a 1.5" diamond holesaw for $17.99 .. I can get about 8 holes out of one through 6mm glass. They're the same brand you bought from summit tools, 'samona' brand.

Dewalt doesn't make diamond holesaws as far as I know of, and it's not in their catalogue.

$80 for a diamond bit? Do you mean a coring bit? If so .. don't use it on glass!

[monocus]

the venting seems to be ok but check the amount of diamond encrusted on the hole saws -as for the sanoma brands-these holesaws are good for about 4 cuts through 3/4 glass-thats why i bought one to replace the set gradually that cost me $80 for one bit-when i buy my tools i sometimes buy cheap to get a quick job done then i will gradually replace them with something that will last me a lifetime.the 2"bit i bought i will probably never have to replace where i have worn out 3 of the sanoma bits-as i said you get what you paid for

[monocus]

sorry i was using dewalt as an example-that was a regular hole saw i bought for construction.and it wasn't a coring bit-it is made for glass and stonework(cabnetry),but will last me more than i will be able to use it

The THK holesaws from Hong Kong (on Ebay) will get you about 4-5 holes on 3/8" glass. Considering they cost under $15 and shipping is free, at $3 a hole they are well worth the price.

I was back at Rona today the bits are returnable when worn out. Or so the packaging was saying. It's there Eco line how good the warinty will be on something like this is hard to tell, but if they replace it when it's worn out hey that is money well spent. The quality looks ok. But if you are going to buy from eBay look at this as well it cost almost the same.

Too bad Sears or Canadian Tire don't make them in their brands. We'd never buy another one.

Not sure but this might be a 'limited' return policy where you will get a new bit for a reduced price when you return the worn one. The local Windsor plywood outlet has the same policy for certain brand saw blades etc.

I've got an old plain steel one that you silicone around where you're going to drill the hole, add water and then add a cutting compound. I've drilled a bunch of holes and bought a couple more bags of cutting compound and the thing works great. You have to use a drill press though or something to stabilize the bit or it will skate around if you try it by hand.

A steel tube or brass tube drill is used with silicon carbide abrasive media. The old fashioned way to drill glass, but the most cost effective if you're doing lots of holes.

Interesting thing I learned today at work, you can actually get a 'sharpening stone' for diamond hole saws! It removes some diamond grit and bonding material exposing fresh new diamond. Apparently each holesaw can be 'refreshed' only once. Going to order one in and give it a try on some of the samona bits in my shop.

I bought an 1.5" hole saw from MOPS and it worked great. The best part is no duties to pay.

The Rona Eco brand is an exchange program. Similiar to a core charge for car parts, or a propane tank exchange.

Basically, you buy the bit/blade/saw you need for full price, and when it wears out you bring it in and buy a new one for less when you trade in yours. They then take the old ones and resharpen them (in the case of sawblades).

Various outfits have been doing this for years.
