• Cobalt Prentice Drills offer increased hardness, toughness and better wear resistance compared to regular HSS
• Gold Oxide surface finish provides a polished finish and prevents chip building, galling and welding on a workpiece
• 135° split point for fast penetration and accurate starting (self-centering) which eliminates “Walking” and reduces the thrust force needed
• 1/2” Standard Reduced Shank to expand the size range capacity of 1/2” drill chucks
