Circular saw blade to cut brass tube

[Geoff_S]

I have got to cut up lengths of 1/2" hollow brass tube. A lot of them!

I am trying to find a 184mm diameter - 16mm bore circular saw blade but I am Googled out.

I have found a Trend one that cuts alloy, but that is as close as I can get.

Has anyone got any advice please?

A blade that cuts aluminium usually cuts other non-ferrous metals - https://sawbladeshop.co.uk/OMEGA-Non-Fe ... -Chop-Saws

Aah, that might do it, thanks.

A recipe for a disaster IMHO. General rule is three teeth in contact with material at all times and for tubing that means a very very fine pitch.
A bandsaw with the speed reduced or a proper metal cut-off saw.
Another possibility is to get you tube supplier to supply them ready cut. They should arrive nicely de-burred and typically 0.5mm length tolerance.

As Myfordman has said a blade with extremely fine tooth count would be needed and would still be very dangerous to cut tubing of any sort the best thing is cut off saw like this

Is the circ saw your only option for cutting the tube? If so please make it safer by building a jig. large square block of wood with a hole drilled for the tube so it's completely enclosed would be fast and easy and make your cuts clean, accurate and repeatable.

Thanks for the warnings as well.

I was hoping that there would be a blade like you get in an angle grinder available and I was going to create a jig to hold the tubing firm.

I approach this with trepidation and I think that the dedicated cut off saw suggested is the way forward. I didn't know such a thing existed.
It's just that I would be unlikely to use it again. However, thanks to the suggestion, I have had a look and found a Sealey machine, new, for £70.
Taking into account what I would have to pay for a blade this might be the route to take.

Watch out for a little used Sealey cut off saw on ebay!

Or I can hire one for the day for about £30.00!

Problem definitely solved, thanks guys.
