Features:

>5/8"diameter drill bit with a 1/2" shank diameter.

>Gold oxide finish enhances rust resistance while improving lubricant adhesion for smoother operation in tough materials.

>The 138°split-point tip eliminates walking for accurate starts without pilot holes.

>Shank has a slight triangular shape to prevent the bit from rotating in the chuck when cutting/drilling into metal or wood.

>When drilling into metals such as cast iron or steel, lower speeds (RPM) work best. It is recommended to use an electric drill equipped with a variable speed trigger switch, or connect the electric drill to a simple plug-in variable speed controller, or use a drill press with adjustable speed.
