I was flipping through the new Craft Supplies catalog and reached the page with all the coring options they offer. The Oneway has a replaceable tip. That powered the light bulb over my head. What if a Hunter carbide cutter was used on a coring system? Seems it would cut pretty quick and stay sharp a long time. If the cutter is slightly larger than the thickness of the shaft, I'm guessing it would be as non-jamming as any of the other designs.
Mike put a Diamond shape cutter on one of my Kelton bars. It works great. Unfortunately that was just a little bit before my move so I haven't had a chance to use it again. I may be wrong but I think he offers that service. I'll try to remember to ask him at the AAW symposium.
It has been done and it's available. I was fortunate enough to be one of the people who tested the idea and really liked it. Mike is able to "re-tip" coring systems with a specialized cutter. Steven Antonucci has a video of a Hunter re-tipped McNaughton on facebook.
The Oneway coring system sells the older HSS tips and has started to offer a carbide tip as well. I haven't tried it since I have a number of tips that still have a lot of life left in them.
I loaned my coring system to an acquaintance and he ground all the harder steel off the top of the cutters. Mike rescued me by installing some of his cutters on them. Its been a while. May have been one of his earlier versions of this product. They work great. The diamond cutters could be slightly wider to cut a slightly wider path.
For starters, it is a HUGE improvement in cutting pressure. They cut with almost scary ease. My only comment to Mike was that if the cutter was a little wider, it would probably self eject the chip (because the cutter "folds" the chip slightly) and you wouldn't need to even stop to clear it once.
My knives were ground down to almost nothing, so I had nothing to lose. I wish I had done it sooner... Not sure if link to video will work?
I had one done years ago, and it might have been the first one Mike did. First tip was a long spear point which didn't work. The second one was a square tip set at a 45 degree angle. It worked but was barely wider than the blade, so it didn't work very well either other than it cut nice. I have 2 blades that I put tangung on (same cutting material as on the Big Ugly tool), and it works great. I did send a piece of it to Kel so he could play with it. The carbide tips might work on the Oneway. My favorite and best cutting tip for the Oneway is one that I had them send that was hardened and tapered, but they hadn't ground the point on. I put it on and it protrudes maybe 1/4 inch from the blade. It cuts way better than the point tipped cutter, and more aggressively also, which is why they don't sell it that way any more. Too bad. Replaceable tips would be nice. Not sure how they will work for long life with the McNaughton, primarily because the blades tend to wear and bend. Maybe replace once or twice. New blades is a big part of Kel's business.
I guess the fact that I have yet to add a coring system to my aresnal might be why I hadn't thought of it sooner. Glad to see others weren't asleep at the wheel. Be nice to see someone offer it as their default configuration.
Have been using Johannes Michelson's Magnus Core Tool for years since he 1st came out with it which has a replaceable and reversible carbide tip that I've yet to replace, it cuts flawless.
