For aluminum, does it help the blade last longer to run it at lower rpm's (3200 or less)? Ferrous blades dull quickly if run over 3200rpm.

Not really sure about the speed, height of blade cutting into surface, speed of feed, clean aluminum, and use a we drop or bit of lubricant on material all helps blade to last , according to friends who work with blades more frequently than me. hope this helps. I do like this blade, cuts great and leaves nice edge. cheers Stu.

I can't tell that blades last longer if run slower. From my perspective the faster you run them the smoother the cut on aluminum.

Not sure about that, but I cut quite a lot of aluminum with my radial arm saw running at the standard speed for that saw. I'm thinking it runs at 3600 rpm.

If your blade is dull, any oscillating tool will fail to cut. Make sure that's not the problem. I also bought a Dremel MultiMax first. It lasted about six hours. I have only used the Rockwell for 1-2 hours, but it does seem to cut better than the Dremel ever did.

I don't know, mine has never lasted long enough to dull the blades. I've gone through two of them thus far. Probably on the waring site.

The backbone of the blade is stainless and the cutting edge of the blade is D2. You can see the fusion of the metal in the blade at the wavy gold line. It will rust, including the stainless portion, if not kept dry and oiled, but the edge is more prone to doing so. The D2 holds a better edge than stainless and depending upon what sort of work you intend it for can hold up better.

I occasionally use a steel for two or three swipes just to be sure no small burs are left on the blade. Probably not really necessary, but old habits die hard. Very little metal removed and the sharpened blades seem to hold their edge for at least a month.

two different types of steel for the blades. the one you are looking at has aus 8a. the other one is san mai 3. the san mai 3 is supposedly a better steel. I have owned one of each. I loved the aus 8a, but wanted to try the san mai 3. That being said, I haven't had the san mai 3 long enough to tell you that it truly is better, but for the slight price difference I would recommend you go with the san mai 3. Did quite a bit of reading on it, and it appears to be the better blade. (I'm not sorry I upgraded so far)

The shorter stroke will cut faster, I find in cutting metal its much smother.

Yep, definitely get the GK or GKP if you can afford it. Either is far superior to any of Cold Steel's stamped metal blades, like the RK. Sure the less expensive blades have the protective coating, but once it wears off through sharpening and use, it is just as susceptible to corrosion if not more so. The GK and GKP are monster blades, light and durable, and if properly maintained either will outlive you.

I honesty cannot say. I had both. One burned out so I bought the other. As long as we had it we did not dull the blade out. Sorry wish I could be of more help. I can say they are both equal in quality & the motor is as powerful in both. Thanks

Yes I'm agree of this die grinder rpm low. You must increase of air flow and amount from compressor.By increase of air regulator guage on compressor and max open valves in supply line.

I used this blade for cutting Lock Dry aluminum decking and it worked well. I did not even consider using it for miter saw wood cuts because of the high blade count which I thought would clog. I went back to my carbide tipped wood cutting blade and use it for all my wood working.

I was wondering the same and also that given the fact that both have the same motor, I was wondering if the 4th blade would hit the overall performance. But since JR felt it even a bit quicker then all seems to be ok.Thanks both!+Alfredo

I had one that was very noisy and would not even run at all speeds so I contacted Dremel. They sent me another and it was still a little noisy, they are known for that, but it was much better and I am still using it.

I bought the S30V steel because it is the hardest and densest metal particles available. The others are close but no cigar. The average user will never notice the difference. If you are a blade nut, each blade steel has its advantages and disadvantages. I have some experience with blade steel and put my trust more in the powder steels as best. Remember, when it comes to blade steel, you get what you pay for.

I had the motor slow down when the knife I was sharpening was a thick blade. Just hold it with a lighter touch and it worked fine.

I agree with Big Tex. Aluminum, copper and maybe brass you probably could use the same wood cutting blade with a slow feed, with steel you would want a finer tooth (I think the rule is min 3 teeth in the cut at all times.) I've cut aluminum without any problem, haven't tried steel.
