Infinity Tools Art-Deco 交換用ナイフ Insert-Pro 延長ほぞヘッド用

I’ve been running these knives on my tenon head for a few weeks now, and the C4 sub-micron carbide is holding its edge far longer than any brazed cutter I’ve used before. The fit on the Insert-Pro head was snug and precise, no wobble at all. Clean cuts on hard maple, zero tear-out so far.

The C4 sub-micron carbide is noticeably sharper than standard cutters I've used, and it held that edge through a full run of tenons without any burning. This knife is a solid upgrade if you're running large shaper heads.

Used these in the tenon head on a pretty heavy run of white oak and they held the edge far longer than the old brazed cutters I was swapping out. The sub-micron grade really does make a difference in the cut finish.
