Use an easy-out of harder metal after drilling a small hole with harder metal.
The homophone for drilling a hole is "whole."
Drilling is the purpose for drill in the metal /earth in depth in different shape is called drilling and boring is the size of the hole large/clean the surface is called boring.
Drilling centre and guided drilling get your hole in precisely the correct place.
It really depends on the material you are drilling. Thinner material will use a smaller pre-drill bit. Try drilling a sample hole on a piece of scrap or where it will not be visible Then try your screw. Adjust your hole size if necessary
The hole will need to be drilled to a larger size, and tapped. If possible the part needs to be removed, the metal shavings that fall on the inside can get into the cooling system and cause serious damage.
On a pedestal drill the workpiece is static and the drill is in a vertical position and rotates. On a lathe the workpiece rotates but not the drill, and the drill is in a horizontal position.
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.
A small hole is drilled into the skull
With a center punch and hammer.
Hold up the elevators to trip in the hole.
The rotating action of the drill bit makes the hole.
