I ‘ going to cut an access hole in the tunnel to repair a clutch tube clamp. Question is: Zia my Dremel pictured gonna do the job.

Yup. That will work fine.

Probably the perfect tool, take it slow and not too deep

I used a die grinder and it worked well, took out the almost the entire top to clean the insides of the tunnel.

I use one of those all the time for just that type of cutting. Agreed, take your time. It may be helpful to draw where you want to cut, and practice trying to get the blade perpendicular to the metal so the cut goes in straight. Sometimes it's helpful to go lightly first to create a "guide cut." You may end up going through more than one blade, as they do tend to break.

Wear your safety glasses.

For sure !

N95 mask as well...the resin in the blade will do you no favors. Throw an old beach towel or bekins blanket* around the work area, protect the interior (*spray a thin mist of h20 on it) keep from sparkin' up with the hot cinders

Perfect tool. Buy more blades than you think you need.

Thanks for all those tips, I’ll post pics later.

The dremel cutoff wheel works best when you take slices off of the metal. One guide slice cut then run through either one side at a time or all around taking just a little bit off each pass until you break through.

I would never cut the tunnel, there are better ways to repair a broken clutch tube.

A grinder with a thin blade 5 for 6.00 at harbor freight will be better and easier to control . The dremmel will work but wants to walk away . Either will cut your fingers off equally

Please share!

I couldn't agree more. I always wear a mask. Even a little cutting without wearing one really kills my sinuses.
