alllllllright, wait a dang sec. Using oil with a hacksaw?
A friend of mine insists that you should use [any] oil (he uses olive oil) when using a hacksaw. He says that it keeps the blade from wearing out but does not impede the cutting. I just can't quite understand this. I understand that the blade's job is to have the teeth bite (and not wear through the item via friction heat) but it just seems to me that oil will make it nearly impossible for the teeth to grab hold of the item. Can anyone shed light on this? |

Can anyone shed light on this? I've used WD-40. Cools the blade, cuts faster. MJ |

Can anyone shed light on this? Hacksaw teeth will bite into metal just fine even if the cut is saturated with oil. The purpose of the oil is to keep from wearing the teeth out, and to reduce friction so that the blade doesn't heat up so much it loses its temper (toughness and hardness). Try it sometime on a piece of scrap steel, say about 1/8" thick. Make one cut without oiling the blade, then another cut with oil on the blade. You'll find that with oil, it cuts faster and smoother with less pressure, less noice, and less heat. |

Well, by your reasoning, no cutting tool--drill bit, milling cutter, broach--should cut if immersed in oil. But they all are when used in industrial cutting machines, so I guess the oil is good for the tool and good for the cutting operation. For one thing, it helps flush chips away, as well as cooling things down. -- I am a Canadian who was born and raised in The Netherlands. I live on Planet Earth on a spot of land called Canada.

Can anyone shed light on this? IMHO the lube is going to cut down on friction between the side of the blade and the material being cut. When first starting the cut you probably will not notice any appreciable difference when using a lubricant. Will the lube keep the blade sharp? No, probably not but it will probably aid in keeping the teeth clean and that will in turn give the effect of the blade staying sharp longer. |

t... It does contain some light oil, not sure what else, I haven't looked at the blurb for a couple of decades. Also heard of people using kerosene for the purpose. My dad taught me to use kerosene to rinse glass cutters and lubricate and clean the surface when cutting glass. We cut a lot of glass in our hardware store during the many years we had it open. |

Can anyone shed light on this? You are machining the metal. A lot of metalworking machines spray oil or an oil/water mixture onto the cutting tool during machining. Oiling the blade is a simplified version of that with the hacksaw. With that said, I'll admit I seldom use oil unless I am cutting a very large or thick piece of stock. Then it does seem to speed up and smoot the process. RonB |

oil) when using a hacksaw. He says that it keeps the blade from wearing out but does not impede the cutting. Same principle as using wet sandpaper. It carries the "swarf" off and keeps the gullets open. -Zz |

Wood cutting benefits from oil too. The trouble is that the oil soaks into the wood and can't be cleaned off, so there's a downside that outweighs the benefits. FWIW, Bosch used to sell a blade oiler for their jigsaws, intended for metal cutting. |

If you get steel hot enough to "blue" you have affected hardness/temper and damaged the blade. Absolutely NOTHING wrong with using coolant/lubricant on a hack-saw - and if you are attempting to cut aluminum it is a EXCELLENT idea as it keeps the teeth from "loading up" |

I have a 'blue max' - maybe different in spelling - hacksaw that
is a 4" 'tall and about 24" long. Thick. I was in the process of making a wood saw - like a bow saw - from it - for really nasty wood. I just got out my 1 man buck saw that cuts down a tree and used it. It has a standard looking hand saw and a post for the far end if needed.
