I've just ordered a portable badsaw from HF. I remember reading that blade that come with it is pretty bad. What would be a good blade for this saw and where to get it? BTW I'll make a vertical stand for it and will be cutting carbon steel and stainless up to 1/4" thick.
Milwaukee bimetal blades if they'll fit. They probably will.
You don't say how thin you might go. Use a blade with pitch fine enough to have at least 3 teeth engaged in the cut. If you don't do that you'll strip the teeth off of any blade in short order, particularly with stainless.
A blade that is finer than necessary will just cut more slowly.
************************* I went to a local plumbing wholesaler and picked up a 3 set package of Milwaukee bandsaw blades from them for about $23.00. They said all the local plumbers used these blades... I am very happy with mine, as I am still on the first one, after fairly heavy use as a hobbist. (I built a wooden laminated stand and use my portable mostly as a static bandsaw on angle iron and strap, on low speed.) I too have the two speed HF portable bandsaw, and have no complaints, considering the low cost. I do release the blade tension when not in use. I use a spring clamp on the trigger, and just use the plug as the on-off.
