# Work instructions for drilling

Use a drill emulsion or cutting oil for cooling and lubrication in order to prevent the drill bit from overheating or jamming.

For drilling diameters > 10 mm, pre-drill with a small drilling diameter. This allows you to reduce the contact pressure and puts less strain on the power tool.

When drilling into metal, only use sharpened HSS drills (HSS = high-speed steel) which are in perfect condition. The Bosch accessory range guarantees appropriate quality.

The machine vice, which is available as an accessory, enables the workpiece to be securely clamped. This prevents the workpiece from turning and any accidents this could cause.
