What saw blade is this?
What kind of saw blade is this? Damned if I can find one with teeth like it anywhere. Needed for an indexing disk, as shown.

Is it a blade for cutting aluminium section?
I saw one like it in the joinery where I had had some aluminium windows made. This was on a rather sophisticated saw with a pneumatic lock down system.

It looks like an old, pre-carbide tipped tooth circular saw blade.
I don't think they make them like that any more.
There must be lots of them still in sheds. Ask around? How many teeth do you need?
Carbide tipped teeth are standard now.
If it's just for indexing and you just need the certain number of teeth, does it matter if the carbide is there?

Agree, just a standard wood cutting blade, I have a heap here for my table saw.
I bought a box of them cheap on eBay about 12 years ago, didn't know they where now unavailable.
Try a saw sharpening place, I used to have mine resharpened and they might have one laying around not picked up.Using Tapatalk

Looks like an old HSS circular saw blade.
How big do you need it.?
I think the old boy still has a few floating around in the bowels of his shed, I can take a look next week when I’m down there next if you like.
I don’t recall him ever having a saw bigger than 7 1/4” (185mm) though.

It looks to be an old style HSS blade (ie: no tungsten carbide tip). I suspect, but don't absolutely know, it was called a combination blade, which meant that theoretically it could rip or crosscut in wood. In practice of course that meant it did neither as well as it could. I think aluminium cutting blades have a negative rake so they don't dig in, but that is a little difficult to see in the pic. Although it looks quite aggressive, that may just be camera angle.
A Google search for "Combination Circular Saw Blade" may give you some clues to whether this is what you have.

Some more searching on youtube and I think I have identified these fine tooth blades as Steel Cutting blades.
At the top of the blade it says STEEL (upside down) so best guess is a cold saw blade??

I am no expert although cold saw blades normally have round gullets and a rounded tooth profile

Hi Guys,
That word "steel" on the blade likely refers to the fact that the blade is made of steel. I have some old Black & Decker circular saw blades that say steel on them, but since I've sharpened the odd one with a file, they are no harder than a longsaw wood blade, so definitely will not cut metal.Best Regards:
