Hi All

Thanks
Rob

does this help any,
The ring with the slot is for setting the cutter to maximum depth

You make your own cutter out of some 1/4 high speed steel stock. Most machine tool shop sell. It will need to be shaped using a grinder to match the groove needed.

thanks 1930 Coupe.
would you have a close up picture of the cutter.

Regards
Rob

It is a very unusual cutter, it just pushes in and must be free to rotate. A spring clip keeps it from falling out.

I just use the small ball burr that comes with a Dremel kit. With a steady hand, the results are fine. It's dark in there so the oil can't see the difference!!

Thankyou 1930 Coupe
Seeing the cutter now makes sense.
As i have the jigs i may as well use them.
the guide channel on mine has been damaged so i will need to repair them first.
i assume someone tried to put a standard cutter in it with out the front guide and it took a chunk out of the guide.
i will make a drawing of the cutter for future reference.

thanks again
Rob

Interesting because my original cutters did not look like that. I will go down and take a picture when I have a moment.

Thanks Terry.
Easily made made from high speed round stock, probably 5/16? Notice the relief angles on top and sides. Machinist call them form tools and sharpen using a abrasive honing stone.

The material that is being cut has to go somewhere. It usually tries to curl up. The one pictured in post #5 doesn't seem to allow for that. I think someone was looking for a way to control the cut somehow but I'm not sure how it would work or if it would even work at all.

I have used it many times and it works great and makes a very nice grove.
Are you saying that I need to stop using it and put it in the trash

Without going to look at it it im pretty sure mine has a cemented carbide tip. Maybe thats why the odd shape on the one shown

For "ripping" thru soft metal at a snail's pace, what would the advantage of carbide be? I would think it would have been an unnecessary waste of money. Am I missing something??

I just haven't seen how a bit like that will push out the cuttings. I didn't say it wouldn't work, I just can't visualize what the cuttings are going to do. On the one in Brent's info, I can predict what the cuttings are going to do. If it works without balling material up then that's great.

If you think I inferred your last statement above in my last statement on post #10 then you are reading in something that isn't there.

I am happy and OK, just did not want other people to get confused.

If you tried to hog it through with one heavy cut, then it might do like you said.
I take 3 or 4 light cuts and it works great.
