Hello Guys,

Well this has never happened to me.

I use a 45465 bit to remove exess adhesive from our dropedges, we use it to skim the whole 1.5" edge, we remove about half a milimmeter.

The new bit gave me about 60 8ft runs. I send it to resharpen, with our amana dealer, and when I got it back we tried it and it was worse than when we sent it, we couldnt even cut one 8ft run without running to protect our ears.

I sent it back with our dealer and he checked it, got it back same thing. I talked to him and he told me that since that bit is not designed for corian, he couldnt guarantee that it should work.

I told him there are no template bits in the solid surface section of the amana catalog. He told me that he couldnt help me in this case.

Anyone ever had a case where a resharpened bit didnt work? AT ALL?

BEst Regards

Fernando.

the 45465 bit has a D of 3/4", B of 1.75"

That bit right there, from Amana or any other brand is one of the most popular for Solid Surface.

Well it was sharpened on a manual grinder, I cant think of a sharpener here in mexico that has cnc equipment for that.

And when asked about the grits of the wheels, he said, 800.

I asked him if he used a sequence of grits, and he said no, just 800

Thanks

Fernando

Hi Andy.

Im not stuck with that guy, i just was sending him my bits because he was the distribuitor amana gave me.

Im looking for some other options.

Thanks!

Fernando

800grit and 800grit only IS NOT going to cut an edge on a bit.  That's your problem right there. To fine. In the world of sharpening, 600grit is  preferred. Even a little courser if the bit has a flat spot on the carbide edge from over use.

Send it to Dave, he sharpens bits.  Obviously it would cost you for shipping, but if he can get it sharpened nice, you will know it's not the bit, but the sharpener.

I found another distribuitor for amana, and they have a sharpening service too...

Ill give them a try

and tell them what you haave just told me.

Regards and thanks!

While 600-800 grit may be fine as it relates to abrasives, it's not when it comes to diamond wheels for sharpening. You have to cut the edge. That 800g wheel was probably akin to running a buffing wheel over the tool so it was as dull as when you sent it out but probably real shiny.

Last week I changed to a newly sharpened single flute 3/8" bit.  I cut about 8" of Delta Sand Corian and it wouldn't cut anymore.  Gave it back to the shop that did the sharpening and they were puzzled, but are giving it another go at no charge.

That is the same thing that happened here, but after the second sharpening the seller did not want to take responsability for it.

I took it to the other place I mentioned, they shapened it in 10 minutes while I waited.

Tried it, and it cut, not as well as the original, but FAR better than the 2 tries the other guy had. It is a little bit out of balance though, I can fell my 3.5HP milwawkee router vibrate a little when i turn it on

Just a little more sanding i guess.

Thanks

Fernando

When's the last time you changed the collet in your router?

I never have changed the collet, but it worked fine just befor puting the new sharpened bit.

Thanks!

Fernando

Fernando, not saying your collet has anything to do with it however, changing tha collet in a router needs to be done periodically. You mentioned vibration which is one thing that could be coming from a bad collet.

Automated grinding.

I had a vibration problem after changing bits.  It was combination bad collet and little bit of dust in there.  When you look at the collet, it won't look any different but once you change it, there is a huge difference in performance.

"Mirror finish" would be ending with 600g. Correct. Beginning with a 280-400g depending on the dullness of the bit. Automation helps. Manual grinders have come a long way but they're not CNC grinders.

Fernando was told they used 800g only.If they did, they don't know what they're doing.

Kind of violates every principle of polishing, yeah.

800g is not going to cut an edge. Perhaps Fernando just got a guy on the phone that had no clue.
