HOW TO SHARPEN A ANNULAR CUTTER

[@brucewilliams6292]

You did a great job of explaining what you are doing and your camera person did a great job. Thanks for the video.

This is very interesting! For a layman, I'd also be interested to see if there were practical methods for repairing/dressing/sharpening holesaws utilizing less advanced machinery.

[@Lappemountainliving]

Interesting concept. I'll give it some thought and see if I can come up with a method of sharpening, (But without ruining) some of these things with tools most guys have at home. Thanks for the comment!

Interesting to see how this is done in practice. We use a lot of anular cutters at work, perfect for punchung holes with portable machines. There is one thing you didn't do that our anular cuters have, and would have helped you drill a bit easier. That's alternating the teeth between having the crest of the tooth offset to the left, right and center. That way, each tooth only sees 1/3 the load. Over all feed rate is slower though. Not sure how you would do that with this setup though.

The staggered tooth effect is normally done on larger diameter annular cutters but it could have been done on this one. It would be easy to do using the method shown. I would just go a little deeper on every second tooth on angle 1 and then go a little deeper on every other second tooth on angle 2

Hello from Aus. I use a saw gulleting wheel to grind the gullets. 150 X 3 X 31.75mm Ruby alox 80 grit. it does well. Also the clearance grinding issue for the inner facet is easier if the wheel head is tilted and not the workhead. Why I don't know. For facet grinding I use an 11V9 wheel. 38A60 KV.

Sub! Thank you for sharing your knowledge on sharpening. This subject is kinda black spot on YT.

What kind of rpm are you running at that you can run without wheel covers and not worry about personal damage if the wheel explodes?

[@Lappemountainliving]

3450 RPM I would recommend that everyone uses a wheel guard at all times.

[@davidharper4289]

Mmmmmmm 250 RPM and Push How many rpm where you going? I suppose you could always reduce the cutting angle on the cutter. Anyway, great. Cheers again, Davo

[@Lappemountainliving]

I didn't actually check what RPM I was at. My gut tells me that I was going much faster than the cutter wanted to go

[@mashed-out]

Nice hole saw bro!

[@Lappemountainliving]

Thanks 👍
