Infinity Tools 軸承止動環用內六角扳手

Lost my last set of stop collars somewhere under my bench, so ordering a fresh batch was a relief. These Allen keys fit the set screws snugly, and having a full assortment means I finally have backups when one inevitably rolls into a dark corner.

These stop collars have a much tighter grip than ones I've used before, so my bits don't wobble at all. The hex keys fit securely and give good leverage for adjustments. Really solid feel for the price.

Third set of these I've bought because they keep getting swiped from my workbench, and the stop collars are a nice bonus since I always misplace those. The keys have held up well through heavy use, no stripping on the hex ends so far. Just wish they came in a little case, but that's on me for not or
