Any HSS drill bit will make a hole in a nickel. Be careful how you hold the nickel as the bit will very likely jam into it. I use 'vice-grips' when doing something like that, pliers are not strong enough.
To drill a bigger hole in an existing hole, you can use a larger drill bit than the one used to create the original hole. Place the larger drill bit in the existing hole and drill through it to make the hole bigger. Make sure to use the appropriate safety precautions and techniques while drilling.
The rotating action of the drill bit makes the hole.
"Drills" is the plural of "drill". A drill can be a tool used to make a hole. A drill can be a military procedure.
To attach a Hole Dozer to a drill, simply insert the shank of the Hole Dozer into the chuck of the drill and tighten it securely. Make sure it is centered and secure before using.
Drill?
To make a hole in or through, with or as if with a drill.
To drill a pilot hole effectively, start by selecting the right size drill bit for the screw you will be using. Mark the spot where you want to drill the hole and then slowly drill into the material using light pressure. Make sure to keep the drill straight and steady to prevent the bit from wandering. Once the pilot hole is drilled, you can then drive the screw into the hole with ease.
An auger drill is a special drill used to make holes in things. It works by drilling while also pulling the material out of the way to leave a space. An example is an earth auger drill, which can drill a hole into the earth while pulling the soil out of the ground.
To attach a hole saw to a drill, first ensure the drill chuck is open. Insert the hole saw shank into the chuck and tighten it securely. Use the drill's key or hand-tighten the chuck to secure the hole saw in place. Make sure it is centered and secure before using the drill.
To drill a flat bottom hole, use a drill bit with a flat end or a spade bit. Make sure the drill is set to a low speed and apply even pressure while drilling. Keep the drill perpendicular to the surface to ensure a flat bottom hole.
To effectively drill a straight hole, start by marking the spot where you want to drill with a pencil or marker. Use a drill press or a guide to keep the drill bit straight as you drill. Apply steady pressure and drill at a slow and consistent speed to ensure a straight hole. Check the alignment periodically to make adjustments if needed.
I would use a "hole saw".
