Saw Blade Sharpening Disk

Want to build a saw blade sharpening machine from a 4 1/2 in angle grinder. What grit diamond disk should I buy for sharpening carbide tipped saw blades?

Check the parts list in this manual first to see if you really want to build one. HF has this for $55. The disk description for it is: 4 in. diamond wheel for carbide tips, 4 in. emery wheel for steel tips

Just like chain saw and drill bit sharpeners maintaining the proper angle is the most critical requirement, if your just going to hand hold the angle grinder your results will be poor regardless of the disk/stone used.

Grinder will be attached to table with grinding wheel at 90 degree angle with table top. A moving platform will hold blade and be moved to and from the grinding disk. Thanks for the info. Still needing to know what grit disk to buy.

Not sure how the set up will be but both my chain saw and drill bit sharpening tools use very fine grit wheel, nothing diamond!

Hope that helps!

While I don't have much to add, I will say that there are some interesting youtube videos on the topic, if you just type in DIY saw blade sharpening or similar and start browsing.

The topic interests me only because I have a pile of blades about 8" tall that I can't bring myself to throw away. I think I like the table saw sled design the best.

And to the question... the grit one guy recommends is 600. Diamond grit was too course and chewed up his teeth.

Thank you ,XSleeper. I have looked at some of the videos you referenced. Did not catch the one using 600 grit. Thanks again.

I think it was toward the beginning of the video "diy circular saw sharpening jig". He talks first about how diamond sharpening was a fail because the diamond grit was too course.
