Nascco 6pc 1/8" Shank High Speed Steel Mini Saw Blades with Mandrels for Dremel Fordom Rotary Tool

UPDATED REVIEW (1/15/2019): In my previous review, I advised that a "Picture is worth 1000 words", so take a look at the photos I uploaded.I advised the following:"I literally received my saw blade kit yesterday (1/11/2019). I was pleased that the mandrel was the correct size for my TACKLIFE rotary tool (also ordered from Amazon). I put the mandrel and one of the blades in for a TEST spin. I cut a PAPER envelope, and in four seconds, the mandrel bent. This caused a hazardous situation as I held the rotary tool tightly in order to turn it off. Once the mandrel bent, the tool began vibrating horribly, which threatened to fall out of my hands and cause much damage to my property, or cause a severe injury to myself. Since the kit only comes with one mandrel, I am ordering more mandrels from another seller. If the same thing happens with other mandrels, this saw kit is getting returned, as I can't risk it being unbalanced blades."SO, NOW THAT I GOT NEW MANDRELS, in fact, these mandrels were nearly identical to the one that came with this kit, I had no problems with the tool, cutting, or anything. The reason is that these mini saw blades and the mandrel are rated at MAX 20,000 rpm TOPS and, back on 1/12/2019, I had my TACKLIFE rotary tool set to its max rotation: at 40,000 RPM's! This is twice the rotation that these little mandrels and blades were rated for and, thus, is the reason why the mandrel bent so quickly. When you use them at their appropriate RPM settings, these work just fine. If you need something that withstands higher RPM<'s, then buy something else. Otherwise, you will do just fine with these as long as you them properly.

A little thicker blade than I thought, but very useful.

Everything was great, thank you.

all is good

The mandrel was bended after less than one minute of using.
