I have a powered hacksaw that is new to me. I broke the blade to it the other day. I was looking for new ones today & those things are expensive. The one that was on it is 14"x1" x.05". I'm thinking about getting a bands blade from grizzly to cut my own. Any of you do this. What do you use to poke the new hole? Do you think http://www.grizzly.com/products/202-3-4-x-1-x-035-x-10-TPI-Raker-Bandsaw-Blade/H4346 would work? There is also http://www.grizzly.com/products/101-x-1-x-035-x-10-TPI-Raker-Tool-Steel-Bandsaw-Blade/G8795 .

Hi kingmt01,
I have never heard of using bandsaw blades on a power hack saw.
On my power hacksaw the blades are substantially thick.....but the whole machine is way bigger than I've ever needed.
A thicker (stiffer) blade will wander less.
I wonder about any design differences(maybe tooth set?).....hacksaw blades travel backwards in the kerf, bandsaw blades do not.....typically.
I believe the blades should have hardened teeth on a softer band, but how soft is the question.
Did it get hardened some by the (likely) induction hardening of the tooth edge?
Is it soft enough to drill?
I do remember seeing a way to "spot temper" a piece of thin hardened stock. I believe it was in this book:
http://www.amazon.com/Complete-Mode...48&sr=8-1&keywords=complete+modern+blacksmith
It went something like this:
-cut the head off a nail
-chuck the nail in a drill press (flat end down)
-spin the nail against the workpiece at the point you want the hole
-when it gets red hot place it into a bucket of ashes or insulation to cool slowly
-when cool you should be able to drill it
I'll try to double check the book when I get home tonight, and repost if there's any substantial difference.

I don't think it would work iv only seen a few of the hacksaw blades but they were all much stiffer bandsaw blades are meant to bend. I think a good cobalt drill will go through a bandsaw blade at least if its a bimetal blade. If you could put alot of tension on it with the power hacksaw it may work. Bandsaws have alot if tension to keep the blade straight

I have used broken bandsaw blades on a hacksaw. I was able to drill the holes without problems. A sharp bit, heavy pressure, and lube. The bandsaw blades may be too flimsy for a power hacksaw, especially a 14" blade. I have some power hacksaw blades; 12" x 1" x .063 10 tpi. That would be pretty thick for a bandsaw blade.
Mine are a little thinner then that. I read about someone buying blades that the hole size was to small & punching them out. I've also read of people using band saw blades is where I got the idea. It just blows me away that hacksaw blades cost $20 a piece.

They might be $20 a piece, but they last a loooong time. I've had the same blade in my saw for three years now and I am just starting to think about replacing it. I figure I get a lot of cutting for my money, so I don't see it as such a bad price at all. I've also had good luck finding them on eBay from time to time, buying a box full at a time for $10 to $15 per blade. Right now I have enough blades here that I don't think I'll need to buy any for a long time.

Been there, done that, so don't feel bad, you're not the only one!! When I need to cut bolt heads off, I usually clamp the bolt in the vise between two pieces of wood so that I don't hurt the threads, then use a die grinder and a cutoff wheel. Quick and easy. You could also use the lathe, but if you try to use a parting tool to cut it off, you'll have to clamp it too tight and the chuck jaws will distort the threads.
I have a bandsaw that uses 1" wide blades but they are only about .028 thick. If you are near any machine shops you may try asking if they have any that they are throwing away. We throw them away when they get too messed up but I'm sure you could find a decent foot to try with.
