I only use the Bi-metal blades and I get MONTHs from them. While I don't use the bandsaw every week and I only purchased them with the 20% discount coupon(NOW GONE).? I still have 8 blades ready to go.
So about a month ago, the blade in my saw broke while doing a long cut (2" thick/7" long), probably needed lube!? When I got that blade (HF) it also behaved oddly, but
settled and cut really straight.? The new blade (also HF) cuts at about a 7-8 degree angle, which is highly annoying to say the least.? I swapped out the guide bearings, just in case, and although one was toast, it didn't make a difference while cutting.?
Are some HF blades bad from the git-go??
