Chipped teeth on saw blades, cutting aluminum...
Awl --
I do some alum cutting on my RAS, using mostly 60 tooth 10" blades -- everything from 1/8" material, to 3" material, with 1" flat and round bar being typical. How significant is chipped/missing carbide on a tooth or two (non-adjacent)? If a chipped/missing tooth is ok for 60 tooth, how coarse can the blade get before missing/chipped carbide is not OK? If dicey on alum, can these chipped blades be used safely on wood? I will switch to new or unchipped blades awaiting Group Advice. Also, I have a 10" 80 tooth Morse Metal Devil specifically for alum, which doesn't look much different than other non-specific 60 tooth carbide blades -- except the price sticker, $90 !! It was given to me. I just bought an Avanti two-pack of 10" 60 tooth from HD, for $29. Just wondering what diffs between the two blades to expect, if any. Any nifty uses for worn-out RAS blades? Frisbee?? Just scrap'em? -- EA |
