| Use a rag (wearing no gloves!) to grip the shank (the smooth top part) of the bit, not the cutting flutes and loosen the chuck. Wipe it down with a rag soaked in a little oil or solvent to remove all metal swarf and cutting fluid. The cutting edges of the drill bit can reach over 100°C; touching the flutes directly causes instant second-degree burns. Cleaning the bit immediately is crucial because dried cutting fluid turns into a sticky, acidic varnish that corrodes the high-speed steel and dulls the cutting edges over time. | Use a rag (wearing no gloves!) to grip the shank (the smooth top part) of the bit, not the cutting flutes and loosen the chuck.

| Match the size (e.g., 10.0mm) engraved on the shank of the bit to the corresponding labelled hole of drill rack. Storing bits in their dedicated holder prevents them from rolling off the table and falling onto the concrete floor (which chips and dulls the cutting tip).

| Using a stiff brush and a rag, sweep all metal chips off the drill table, out of the T-slots, and off the base plate. Wipe down the vertical column with an oily rag to prevent rust, and wipe any excess cutting fluid off the chuck. | Using a stiff brush and a rag, sweep all metal chips off the drill table, out of the T-slots, and off the base plate.
