The guidescrew makes drilling easier by pulling the drill bit intothe workpiece.Drilling in metalTo prevent the drill bit from slipping when starting ahole, make an indentation with a center-punch andhammer at the point to be drilled. Place the point of thedrill bit in the indentation and start drilling.Use a cutting lubricant when drilling metals.
