Straight-Shank Drill Chuck Arbors with Drill-Feed Attachment
For better control when drilling small holes with a drill press or milling machine, the attachment on this arbor lets you apply light feed pressure with your fingers while the machine rotates the bit. A spring-loaded, ball-bearing drill feed automatically retracts when the gripping ring is released. The straight shank fits into a machine spindle and the Jacobs taper end is compatible with a Jacobs taper drill chuck.
