Hole Saws of the Carbide Persuasion

admin

Looking at switching to carbide tipped hole saws. Cutting stainless pipe, mostly. I have traditionally used bi-metal saws, which have a tendency to fail all at once. I hear people say "carbide is the way to go son," which makes sense. So I talked to my favorite salesmen and he quoted me at $400 for a Champion 12 saw set. I did not expect this after 60-80 buck sets. What do you all that cope & pierce pipe with saws recommend? Brands? Are carbide worth it? I understand plasma is the way to go, but sometimes its out of the question.Constant Current Weldor.

Reply:What kind of jig are you using? I use the drill press with slow speed and lots of lube in short bursts so i dont heat up the stainless to bad. I use regular bimetal hole saws get decent life but I always want to learn a new trick. Makes goos sense to use a lower torque hand drill though.Donnelly Small Engine & WeldingFoley AlabamaLincoln 225 TigLinoln 215 migHypertherm Powermax 65Ellis 1600 sawEllis 6000 belt grinderJD2 Model 4 tubing benderAtlas  12"X54" metal latheLots of large hammers
