Infinity Tools 用於 Insert-Pro 圓弧背切成型銑刀的替換刀片

The C4 sub-micron carbide is noticeably more rigid than the brazed cutters I've used before, and it held an edge through a full run of hard maple without any chipping. Installed easily and the profile came out perfectly clean on the first pass.

I needed a replacement set for my backcutter and these carbide knives seated perfectly with no play. The edge held up noticeably longer than the original steel blades.

The C4 carbide is noticeably denser than the braze-tipped knives I’ve used before, and the fit on the Insert-Pro was dead-on with no slop. Put them through a full day of oak and they’re still cutting clean, no chipping at the edges.
