IRWIN Self-Feed Drill Bit for Boring

Self-feed drill bits have beveled saw teeth and a screw tip that pulls the bits into the workpiece to quickly bore holes in wood without applying pressure. The bits' teeth can be resharpened and their screw tip can be replaced to extend the bits' life. These bits feature a quick-change hex shank and can be inserted and removed from the drill chuck without the use of tools, allowing the bits to be changed out faster and more efficiently than bits with a standard hex shank.
