Thread: curiosity about the twin blade circular saw

I know that you get a cut the same width as you get from a chain saw!

Regards,

Rob

I also wonder if it's a case of the "cheap laser jet printers", ie printer is cheap but cartridges cost a bomb. It's not like you can use third party blades on them and of course you have to replace the pair.

I picked up the "Ozito" version in the store this afternoon as it was on display.
Felt heavy. Also appeared to be assembled in reverse to the image on the box.
I do not believe there is any depth adjustment so it would not be usable for mortices.

Being able to cut in a straight line will depend on either a straight edge or the control of the user.

I recently bought one...a good concept, but useless for anything other than free-hand cutting of melamine. As mentioned in an earlier thread, the width of cut is wide, and depth of cut is about 16mm max. There is no flat base to sit on the board that is being cut, so a square cut is impossible. I feel the only plus it has going for it. is that it doesn't kick back, because of the opposing rotation of the blades. I consider them to be an expensive gimmick.

So a bit like those kitchen gadjets that have one play then clutter up the kitchen drawers???

I didn't look towards the depth adjustment however when I picked it up I immediately thought "yeah this is just like the angle grinder I'm using now to cut up some old iron sheets" in terms of straight lines & control.

In the end I picked up some metal cutting discs for the old '82 ryobi circular saw instead.

I think this Ox branded model OX 240V 185mm Supercutter OX-P850 | Get Tools Direct would be worth a look to my mind it's more like a power saw than an angle grinder which is how i view these twin blade tools

I just got one from Swarts Tools today at the show. I will be there again tomorrow and try to fond out about replacement blades.

Swarts do there saws in 2 sizes. I got the larger. I would imagine the use of a fence would be possible but did not pay attention to my kit. My kit includes a set of diamond blades for brick etc.

If you look at the T & W W W Show Melbourne thread it will be in there a picture of the stand. I will get to update pricing by lunch tomorrow.

Hi Richard

you have to realise that these are essentially metal cutting and demolition saws -- they are not really intended for woodworking or furniture making

Can they cut a piece of mild steel 5mm thick ? 10mm 20mm ? or a piece of sheet metal 0.5mm thick ?

I've seen them on the telly and always wondered about metal cutting capability.

Hey bill. If you check out my show thread I'll have a few more pics for you guys from the Swarts Tools stand by lunch time. I think I saw a picture of someone one cutting through a safe. It cuts corrugated iron and the demo I saw wit through what looked to be a 50mm steel water pipe with maybe a 3mm wall.

Swarts is the only one I s noticed being demonstrated. There are lots of brands. I don't know which is best.

I have used a metal cutting hand saw about ten years ago. It was a makita battery powered saw. It used tungsten carbide blades and had a fixed depth setting. The way it worked and the reference to it was a "swarf cutter" it also collected the swarf in an enclosed blade guard which needed emptying after a period of use. I used this to cut aluminium sheet, extrusions of a range of thicknesses and shapes. I also cut a number of very thick reo rod, which it cut effortlessly and very minimum heat. The method of cut was explained to me the the depth of blade being fixed allowed the tungsten blade to chip metal at almost a 90o angle and very shallow bite as determined by the blade set and teeth depth. This may explain why the depth is fixed on these new dual blade cutters now available.

hope this is of help.

Here is some info by way of pics from the Swarts Tools stand at the Melbourne show.



Their saw is available in two sizes 5" and 6"

I guess with the twin blade it will throw dust forwards as well as backwards.
Any provision for dust (swarf) collection?

Yes I believe there is. Hook up to vacuum or dc
