End Grain - Mcfly Technique Question

[jtclose (James Close)]

There is a link from the recent past about Speed/Feed and the removal on the bottom cutters to improve the results.

McFly Question - burning the wood

Similar to other recommendations, I’d try trading depth of cut for speed. Also however, I would recommend removing the inserts on the bottom of the McFly, leaving only the ones that are perpendicular to the surface of the wood. (Not sure which the OP removed) When taking deeper cuts, the inserts on the bottom don’t clear as well, allowing dust to build up and generate more friction/heat under the cutter.
