Abrasive materials used in watch making

With the twelve piece assorted emery buff sticks, watch makers can refurbish metals and plastics; they can also use them for general purpose cleaning. The sticks have three different grains and under each grain type, there are four sticks. These are ideal to re-grain clasps, touch up scratches that appear on bracelets, feather plastic cases, polish crystals and clean up rusted components. In order to impart different finishes, different cleaning liquids can be used. The Screw Doctor screw head cutter is very useful in re-cutting slots in screw heads that are damaged. This head cutter can be used with all power drills. It is a precision made tool and is made out of hardened heat treated steel which makes it easy to cut out slots. This wheel’s cutting speed is directly proportional to the drill’s speed. This head cutter set has three layered and industrial standard diamond blades apart from one arbour with a washer and screw.

What drill bit type should you use for hollow plasterboard walls? Is it HSS or a wood bit?

It is for putting up shelves and mirrors. I know a masonery bit is not the answer. I think I should use a drill bit in case I hit a metal join in the stud? When I tried to use a self tapping plug alone, sometimes I hit the framework behind the plasterboard, hence why I am thinking of drilling instead. All your advice is most welcome and thanks in advance.
I am using all purpose wall plugs for hollow and hard walls if this helps.
I live in the UK.
Is a HSS Metal bit ok for plasterboard?

Go with answer one simply because it will give you the sharpest cut. Don't be tempted to punch a hole in plasterboard it will break out a larger hole on the inside and make your fixings weak.
