Cutting oil

[Gregor 4,846]

While I was using my sawzall yesterday to cut through the hitch pin on the 876, a thought crossed my mind. Good sawzall blades are expensive, and cheap ones are not worth buying. When drilling on miy drill press, I always try to use cutting oil for anything slightly extensive. Sooooo...I thought, what about that same cutting oil on a sawzll blade. Would it help, or hinder? Your thoughts?

I don't think it would hurt anything to use some cutting oil with a sawzall.  Might be a bit of a mess, though.

 

Both circular and band type cutoff saws usually have a coolant system of some sort.  Usually use a water based cutting coolant or a cutting oil.

As it was mentioned it will be messy and not too effective since most of it will be thrown out by action of blade. I use instead a paste lubricant . The same type used on a circular blade to cut aluminum. It comes in a tube and one merely holds it against the side of the turning  or moving blade. It will stick to blade with heat then spreading it even further. Its main intended purpose is not to let aluminum stick to cutter while cutting but it does cool and lubricate things down substantially. I use it to cut or drill any metal where a liquid would not be practical. Its easy to use and relatively clean.

The best thing I’be ever done for my sawzalls is to get carbide tipped blades!  They are super pricey, but last many times longer than their cheaper alternatives.

We sold Diablo carbide tipped at the hardware store I managed.  Great feedback.  I've tested them at trade shows and was impressed.

It definitely does help. When you're cutting metal on the metal bandsaw you're always using some sort of lubrication to cut with.

it sure will help the blade last longer.

We need to remember that although carbide tipped blades will outlast all other blades, they still benefit and in many cases need a lubricant to perform well and last long. Even when cutting some woods they need a lubricant. In the case of woods such as pine which is highly resinous one needs to apply a dry lubricant so blade does not get caked up with resin and overheat  essentially rendering it useless. It is also a safety issue. Some other materials such as aluminum and any type of plastic such as Plexiglass will adhere themselves to the gullets on the blades creating an absolute dangerous situation if not addressed with the proper lubricant. Besides saving the blades, the lubricated blade will also  leave a flawless finished cut  where the non lubricated blade will leave a rough ragged cut. This is most obvious with aluminum and  Plexiglass but also obvious with any wood. I have a lubricant stick next to every single machine I have and constantly use them.

I would use oil on the metal cutting. I know the same teeth of the saw passover the same area with the reciprocating saw, unlike a band saw have more teeth in the cut allowing it to cool. 

 

This was for drilling but I figure if you have not seen it it is interesting.
