Dave, I was just having some fun...

You should try one of these, just make sure to get the adjustable blade model, it will cut through anything.

Nice! Ribwizzard! I'll check Craigslist!, what I wouldn't give to have that cutting ability! you could probably weld with it too!

Found this on youtube, I don't think they would be selling these at Home Depot if they were not reasonably safe.  I have had an abrasive disk explode on me though.

That's one of the cold cut metal saws, different from your normal skilsaw. They are safe and works great

dfbourg, no the saw in the video is a regular circular saw, look closely, he also says so in the video comments.

Q. "Hi, nice job. A question, is that a regular( for wood mostly) circular saw or is it a metal circular saw? Thanks in advance".

A. "Thanks. It's a regular circular saw, not one designed primarily for metal"

 

[dfbourg]

ok i wasn't paying that close attention but i bet a regular saw doesn't last long doing that

Still hoping someone will post up if they have used one of these blades from any manufacturer.  My questions are not whether or not it is safe to use but how long will the blade last and can you do a drop cut with one the same as you could into wood.  As I stated in my first post I plan on adding an aluminum side guard  to my saw though it appears its not necessary. A woodworking friend of mine suggested I borrow his speed control for his router to drop the RPM of my saw to make the blade run a little cooler and make it last longer. I do appreciate everyone's safety concerns.

I have seen metal cutting blades at the welding shop....  I haven't asked the folks there about them....  The ones I saw were steel blades with diamond edges.....   Don't know how they work.....   I have plasma so I wouldn't use one on my $150  worm drive saw.....

The blade will work but don't know how long. And it will drop cut. Problem is the saw may burn out. Also, cutting the speed is probably not a good idea as all circular metal cutting saws I know of run faster than a standard circular saw. My thinking is slowing it down may help the blade but kill the saw.

 

[dfbourg]

Well at this point all I can say is there is a reason they say use the right tool for the job. Most of the companies that makes the metal cutting saw makes the blade a larger size so it can't be used on a regular skilsaw and cause harm and damage to the saw. Wish you luck in what ever direction you decide to go in and please use caution.

dbourg you are correct   "Discretion "caution" is the better part of valor" I have been working on and around and operating machinery and tools all my life.  I am usually the worry wart about safety and it has served me well to be that way. I have pissed off a few shop owners in my time but I'd rather roll my box out of a job than take a chance that would get me or somebody else hurt. Scolded the neighbor the other day after I saw him trying to remove a brake spring by pulling back on it with a pair of needle nose pliers,  there's a lot of one eyed guys that will tell you why that's a bad idea.

Geerock , actually metal cutting circular saws run SLOWER than a regular wood saw 3200-3900rpm vs. around 5200rpm for wood saws ,do appreciate knowing I can drop cut the blade though

I want to do everything I can to keep from warping the door and make as small and clean a kerf as possible.

These blades are what most people refer to as a cold saw. They have been around for a while and yes, they do work well. Most of the time you will see them used in a stationary cut off saw. The advantage is that they do not heat up the metal like a cut off disc will, giving you a cleaner more precise cut with out the roll over and grinding dust. . You will end up with chips though, a lot of them. So , by that alone, I would recommend using a saw like the Milwakee that is designed for these blades and will catch the chips. You dont want them in your eye, and believe me, there will be hundreds of them embeded in the soals of your shoes. Completely forget it if you want to work with shorts, you will be picking the little half moon metal bastads out of you for weeks after using it.

With the correct saw, they are a wonderful addition to your workshop,....... with out it, your better off with a regular cut off wheel. Good news is the price has come down on these saws.

My mistake on the speed. I have the milwaukee 8 inch metal cutter and was thinking it was 7300 rpm when it is actually 3700. Sorry for the mis info....I'm getting old.

The other night I found a post and pics somewhere on these forums of a member who had successfully used a metal blade in the same skil saw that I have.  I found it by accident and forgot to mark the thread and now I cannot find it.

 

[daveomak]

If you go to your local welding supply house, they have many different types of metal cutting blades to be used with a circular type saw....  metal blades for cutting steel also...  I saw them a couple years ago and was surprised at the selection...  probably a better selection now....
