A question for those using negative rake carbide cutters for resin. Do you see a significant difference from standard carbide cutters? Thanks!
I have heard the NR are much better and Hunter tools make the best.
Who besides Easy Wood and Rikon sell NR carbide cutters? I searched Hunter's site for ‘negative rake’ and got zilch.

Look up Keith Lackner and Mark Dryer. They are both resin guys and NR proponents. Maybe one of them has a video or something.A question for those using negative rake carbide cutters for resin. Do you see a significant difference from standard carbide cutters? Thanks!
Thanks. I was just repeating what I have heard from others.I'm sorry if this sounds testy, but I'm just trying to clarify. Hunter does not make any negative rake (a.k.a. double bevel) carbide scrapers . They do make cupped or pie pan shaped carbide shear cutters . They are made from similar metals, otherwise they have nothing more in common with each other than a HSS skew and a HSS bowl gouge.
Ken, as far as I know Easy Wood and Rikon are the only double bevel makers. But Carter Products makes a Lackner signature tool which mounts a single bevel insert that is tilted to achieve a negative rake presentation.
Mark… look at AZ Carbides. I saw them at the AAW Symposium, but not sure of their line. They were in Carter’s boothI'm sorry if this sounds testy, but I'm just trying to clarify.

Found in Google search, know nothing about this company. https://www.findbuytool.com/product...vWTT2nzsDanaDuI4abZfRdKu417hxSqcaAjuaEALw_wcBWho besides Easy Wood and Rikon sell NR carbide cutters? I searched Hunter's site for ‘negative rake’ and got zilch.

Yup, AZ Carbide is my go to for replacement inserts. He makes replacement inserts for almost all the tools including the NR Rikon, but I don't think he does the EW NR's. The owner, Ron Campbell, is a turner himself and really knows the carbide insert business.Mark… look at AZ Carbides. I saw them at the AAW Symposium, but not sure of their line.

If you take a Hunter carbide tool and hold it so the cupped side faces the wood it becomes a negative rake scraper similar to holding a skew flat and using it as a scraper. However you can swing the handle so the wood crosses the rotary tool at about 7:30 or 8 oclock and now it becomes a shear scraper. I use the #4 Badger in this technique to finish off the inside of boxes. It would work very well on resins in this mode as well.I'm sorry if this sounds testy, but I'm just trying to clarify.

John, this is an interesting point, but I am unclear on how you are orienting the cupped cutter to the wood/resin. Do you have a video or diagram that might clarify?
