You sir are awesome:) I am a professional metal fabricator by trade and would not have came to this solution on my own... hurts to say that lol. Perfect though, low speed = no sparks. Sparks are scary in old houses. Solved my problem. Thanks again.

I went out to harbor Freight and picked up a cheap cut-off wheel for my drill and shortened a duct inside a hard to access joist bay. Worked great! Thanks.

Great demo boss man!! .. But, I would have to write you up for handing sheet metal without gloves..

Very Very helpful video. Thanks 🙏

I'm gonna try it with my Dremel. Thanks for the video!

Great video, thank you!! Essentially an angle grinder blade on a drill driver--which is accessible to most average mortals and non-pros. An angle grinder, sawzle, and drill-driver are probably a good 3 to have at your home at all times for stuff like this.

I bet you the oscillating tool would work nice

Hi, how did you measure the hole?

a pair a red and greens will do the job.

Nice! Great video!!!

Dremel may do it also ??

Really appreciate your video. I've been trying to find a better way to cut into my ducting than with snips. Can you please comment on using what appears to be a cordless drill to this. In the SHARK cut-off wheel product description it says to not use an electric drill, use min 20,000 RPM to max 25,000 RPM . Did it work ok with a regular drill? Thanks

Great video! I've been trying to learn how to cut kitchen ducts, but there's grease I dont want any sparks it might cause fire. Do you think your method would work? I'm surprised you didnt get sparks too

Not much of a welder, but one hell of a grinder.

Could you use an oscillating tool with a metal blade?

Wow !!! Glove up for any metal work! do NOT reach in a metal cut or sandpaper without good gloves etc. Be Happy and ?

Just use a Dremel with a little cut off wheel?
