Looking for a set of hole saws and wondering what people recommend. Has to be a good set that will last and stay sharp.
Thanks!
What application will these hole saws be used for?
For drilling in rough lumber (think: electrical and plumbing), you simply can't beat the 1- and 3- toothed, carbide tipped hole saws. I have a 4 5/16" Leonx 1-tooth hole saw that I regularly use for running 4" ducting. Most important for me is that it tends to not bind as badly as traditional hole saws, very important when you get into these larger sizes. Note that these saws tend to leave a rougher cut, sacrificing tear-out for speed and safety. I believe that Lenox, Milwaukee, and maybe Bosch make these low-tooth count, carbide tipped saws.
For more precision work, almost any brand bi-metal blade should hold up reasonably well. When my hole saws get dull I just take them to my local contractor supply supply and send them out for sharpening. Certainly not inexpensive, but it's cheaper than constantly buying new hole saws.
There are also high tooth count, carbide tipped hole saws, but I do not yet have experience with these.
There are also specialized hole saws for sheet metal, again from Lenox.
Knowing your applications and materials will help guide your purchase. Hope this helps! [smile]
