Infinity Tools Insert-Pro シェイパーカッター用ラブカラー、内径1-1/4インチ

The 1-1/4" I.D. fit my cutters perfectly, and the smooth surface didn't leave any marks on my workpiece. I've been getting much cleaner profiles since switching to these.

Setup was noticeably quicker this time since the collars sit perfectly flat against the cutter, and the heavy-duty build gives me confidence on longer runs. The 1-1/4" bore fits my Insert-Pro spindles without any wobble, so the finish stayed glass-smooth even on hard maple.

These collars spin with almost no vibration on my shaper, which makes for noticeably cleaner cuts. The heavy-duty build gives me confidence on deeper passes, and setup was quick since the 1-1/4" bore matched my spindle perfectly.
