With a ball-bearing stop collar, this stop collar of this drill/counterbore bit stops rotating so the workpiece isn't marred. Chip clearing holes in the depth collar allow chips to clear freely and reduce heat buildup. The 1/8 inch pilot bit is adjustable for protrusion.
Includes a 9/16 inch carbide cutter.
3/8 inch and 18 millimetre carbide cutters, and replacement 1/8 inch twist centre drill available separately.
