Screw machine adapters and holders are special tools developed to mark round parts while they are being turned in a lathe, turret lathe, or automatic screw machine. The mark is usually applied just before the cut-off operation. These holders, mounted directly in the tool posts or screw machine stations, are the stud style construction which permits marking close to the chuck or collet and simplifies the die or holder changes.
