I've read other reviews and I'll say this, if you demand perfection and have the time, build your own set. But if you need to hammer morse taper tools out of morse taper nuts quickly and reliably, buy this set and get to work!
Not to mention steel wedges. The price was fair and they do what they are supposed to do, even better than I expected. I tried everything to remove the chuck spindle before booking the right one for this job.
So they are stamped (or cut) from a bar, and the flat surface that "drifts" on the mandrel is rough with all traces of shear (what the product photo is suspiciously free ). I believe that with a good hit they will work well, especially if they are lubricated. Or of course it would also be possible to put them on a grinding machine and finish the surface yourself - but why? A similar set from Grizzly costs about the same and comes well sharpened and ready to use.
