Thread: Austsaw Rotary Hacksaw

he shot to the right shows a ROTARY HACKSAW cutting through a steel square section like butter with almost no sparks.

How close?

Exactly. It's a pity the web page doesn't open up larger images as promised.

The web site needs a work over to fix spelling and links that don't work.

When I cut the floor, I plan to have a garden sprinkler operating under the car.

Ron,
I have a similar type of saw blade. I purchased it for cutting 50 mm sandwich panels(the stuff that cool rooms are made of, 2 sheets of colour bond glued to polystyrene). It has been a long time since I used it but from memory there were no sparks.

The mob I purchased it from was called Saw Master. All they do is make, sell and repair cutting stuff. They are in Shepparton Vic ph 1800 685 825.
I would give them a call. What they don't know about saw blades isn't worth knowing

I know some plumbers use it on roofs for the same reason. When roofing you are not allowed to use a normal abrasive type cutter as this makes sparks which later cause the roof to rust. There was a plumber around my area a while back that used an ordinary cutter and when the building inspector found out he was made to replace the whole roof.

Would a nibbler be any good Ron?

That is very useful info, Dave,

I need to trim back my carport roofing as it extends too far over the gutter making it impossible to get a hand in to clean it. I had considered a cutting disc but discarded the idea as I reasoned it would damage the Colorbond.

Could be, Scott. I have a air driven shears (not scissors) that cut a slot but it's never been a great tool.

I have a hand-operated Adel nibbler The Original Adel Nibbling Tool but it would be too slow for this.

A nibbler would allow me to cut a round hole where the ssawe wouldn't. They are a bit exxy for a one-off job - it needs to be able to handle, maybe, 16 gauger steel.

How thick is 16 gauge.

Dave.

What is wrong with normal hole saws if you are just cutting an access hole in a floor panel?
