The Graver Handle is different from a pin vise handle in that the collet tip rotates with the handle. The position of the collet and handle allow the tool to remain in the fixed position.
Though the handle is not useful for drilling purposes, it works great for engraving, deburring, for use with a cutting broach or any process that requires a back and forth motion rather than a full circular drilling type motion. This graver comes with two collets:
The small collet ranges from 0 to .030” (0 to .78mm)
The Large collet ranges from .066” to .097” (1.68mm to 2.48mm)
Handle length including collet: 3” (77mm)
