Zero-Set for Test Indicator

• Zero-Set is specially designed for test indicators with dovetails and functions as a quick and practical work positioning device.
• Setting up a workpiece before machining, or aligning the center of a round workpiece in relation to the cutting head, takes virtually no time with Zero-Set.
• Attach Zero-Set directly to the collet, then zero-in the work position by reading the test indicator.
• The hardened clamping post consists of three O.D.s, from top, 1/4", 3/8" and 1/2" and has hardness of approximately 58 to 60 RC.
• The illustration indicates the alignment of a workpiece in relation to the cutting head.
• It reaches anywhere within a 8" diameter and fine-adjusts about 3/8" with a large knurled knob.
• Zero-Set can also be adapted to transfer stands for closer control of the test indicator (in the horizontal direction).
• "Zero-Set" attachment allows for the placement of any test indicator equipped with dovetails or 1/4" posts in a multitude of positions and angles up to 90° on either side, bending both forward and backward.
