فكوك داخلية لظرف 3 فكوك 5 بوصة

The serrations on these inside jaws matched perfectly with my chuck's scroll, so they slid right in without any filing. I’ve already used them for a few aluminum parts, and the grip feels just as tight as the originals.

I needed a spare set for a quick project, and the serrated gripping face on these mates perfectly with the chuck's existing teeth. They slid in with no filing or fuss.

Took the guesswork out of replacing those worn inside jaws on my mini lathe’s 5" chuck, and the fit was dead-on right out of the box. The instructions to double-check inside vs. outside jaws saved me from a silly mistake.
