You drill plexiglass with a standard HSS drill at a low speed and with a piece of wood right where the drill point will exit the work.
Drill bits for concrete always have a carbide tip welded across the point. This is quite obvious as it sticks out slightly each side of the point.
These are to drill in glass
You can use a standard HSS drill bit with the edge slightly dulled with a grinder so it does not 'break through' at the outside edge. -Drill slowly and hold the drill steady. I always put a piece of smooth scrap wood at the point where the drill bit is going to come out.
You could buy a normal drill stand but i feel you will overload the drill and burn out the drill;these use a lever harder to judge the pressure your putting on the drill better with corded drill.ANS 2 -There is absolutely no point in doing this as nowadays small bench top drill presses are cheaper than good cordless drills !
A tek screw is a screw that has a drill bit tip for a point rather than coming to a sharp point like a needle. These are self-drilling screws and need no pilot hole. Tek is a brand name for self-drilling screws as Kleenex is a brand name for nose tissue. self-drilling screws are similar to sheet metal screws but have a drill point instead of coming to a sharp point and will drill their own hole. This eliminates the need to pre-drill a pilot hole.
