Looking for some advice from anyone with experience cutting OSB or plywood with these bits. Where should I be looking to buy these from. Should I go for a larger diameter bit than 10mm to avoid breakages.
I Don't cut wood with Carbide serrated edge rippers but I do often cut aluminium with them and I've cut 10mm deep with 8mm 3 flute for testing purposes and didn't snap it and thats with Chinese WC 2.2Kw spinlde. I regularly cut at 6mm in Ali and it's like knife thru butter so I don't see any reason why they shouldn't shred OSB without any effort.
Infact I've just cut 100 slots 1000mm length @ 10mm DOC with a very very tired ripper in Trespa Athlon resin board which is much much harder than OSB and quite abrasive and it didn't flinch so OSB wouldn't touch it. I get decent tool life in Ali so think you will have no problem in OSB.
