Dremel bit for cutting metal

[jacobsen]

Does anyone have experience cutting metal with their Dremel? I have a Dremel 4200 with the new quick release Chuck. obviously the ceramic Dremel blades are great for cutting metal but they don't last because they grind away. I know that carbide and the diamond are the best kind of blades but I haven't been able to find any specific metal cutting blades for the Dremel. I want to cut open oil filters and other kind of awkward Cuts Like That. I want a bit that's reusable, any ideas would be cool. It's possible to get a bit that lets you screw down your own blade and fit that into the Dremel. So I know I don't have to get a Dremel specific blade. Ideally I'd have a carbide or Diamond blade that I can either attached to a bit and using the Dremel or a Dremel specific metal cutting bit.

The dremel diamond disc lasts a lot longer. I went through all of my EZ speed cutting discs in about a week. I think ive only shaved off about 1mm from the Diamond disc. Costs a bit more but definitely worth it. https://www.amazon.co.uk/Dremel-2615...iamond+cutting

I always use the black "metal" ones for cutting. Not sure if those are the ones you're talking about. They do wear down, but they come in a pack of 5 for like $10 at sears, so you can always pop a fresh one in. For big jobs I use my angle grinder, and even the discs on those wear down.

Typically burrs for shaping things, mini abrasive discs for straight cuts. For hardened steel swap the burrs for stones.

I've only seen joke quality cut-offs with 1/8" arbor though, like this http://www.ebay.com/itm/100pc-Fiberg...-/252383314269

Better ones are typically 1/4" for pneumatic grinders.

For the price you'd be better off getting something like this for straight cuts, since the cutoff tools have a guard for when the discs invariably shatter http://www.harborfreight.com/3-in-he...ool-68523.html (better pneumatic if you have air).

Though to be honest I have all that, and I'd probably just use a hacksaw on an oil filter. Or maybe punch a hole then use tin snips like a can opener.


The burrs dull with use, and the abrasive dics and stones wear away, so there isn't really a single "good for life" bit.
