Drill bits are cutting tools used to remove material to create holes, almost always of circular cross-section. Drill bits come in many sizes and shape and can create different kinds of holes in many different materials. In order to create holes drill bits are attached to a drill, which powers them to cut through the workpiece, typically by rotation. The drill will grasp the upper end of a bit called the shank in the chuck.
Drill bits come in standard sizes, described in the drill bit sizes article. A comprehensive drill bit and tap size chart lists metric and imperial sized drill bits alongside the required screw tap sizes. There are also certain specialized drill bits that can create holes with a non-circular cross-section.
While the term drill may refer to either a drilling machine or a drill bit for use in a drilling machine. In this article, for clarity, drill bit or bit is used throughout to refer to a bit for use in a drilling machine, and drill refers always to a drilling machine.
A drill is a tool fitted with a cutting tool attachment or driving tool attachment, usually a drill bit or driver bit, used for boring holes in various materials or fastening various materials together with the use of fasteners. The attachment is gripped by a chuck at one end of the drill and rotated while pressed against the target material. The tip, and sometimes edges, of the cutting tool does the work of cutting into the target material. This may be slicing off thin shavings (twist drills or auger bits), grinding off small particles (oil drilling), crushing and removing pieces of the workpiece (SDS masonry drill), countersinking, counterboring, or other operations.
Drills are commonly used in woodworking, metalworking, construction and do-it-yourself projects. Specially designed drills are also used in medicine, space missions and other applications. Drills are available with a wide variety of performance characteristics, such as power and capacity.
Around 35,000 BCE, Homo sapiens discovered the benefits of the application of rotary tools. This would have rudimentarily consisted of a pointed rock being spun between the hands to bore a hole through another material. This led to the hand drill, a smooth stick, that was sometimes attached to flint point, and was rubbed between the palms. This was used by many ancient civilizations around the world including the Mayans. The earliest perforated artifacts, such as bone, ivory, shells and antlers found, are from the Upper Paleolithic era.
A bit, also known as a Shannon, is the basic unit of information in computing and digital communications. A bit can have only one of two values, and may therefore be physically implemented with a two-state device. These values are most commonly represented as either a 0or1. The term bit is a portmanteau of binary digit.
The two values can also be interpreted as logical values (true/false, yes/no), algebraic signs (+/−), activation states (on/off), or any other two-valued attribute. The correspondence between these values and the physical states of the underlying storage or device is a matter of convention, and different assignments may be used even within the same device or program. The length of a binary number may be referred to as its bit-length.
In information theory, one bit is typically defined as the uncertainty of a binary random variable that is 0 or 1 with equal probability, or the information that is gained when the value of such a variable becomes known.
In quantum computing, a quantum bit or qubit is a quantum system that can exist in superposition of two classical (i.e., non-quantum) bit values.
We have a look at the most common drill bits, how they work and when to use them. We go through bit selection for large and small holes in wood, plastic, brass, aluminum, bronze, steel and tool steel. We have a look at tungsten carbide and HSS bits. long term projects here: http://www.Patreon.com Lowlights include: -Poking fun at woodworkers -split point versus chisel point -what size pilot to drill -hole saws and slugging bits -Drilling Wood, Plastic, Steel, brass, bronze, tool steel and stone Vid Credit The Highland Woodworker: https://youtu.be/Y2Eg-fR-4oI H.

Hi This is a shorter version of the ' how to sharpen a drill bit', which shows drill bit angles only. It also shows a table that consists of recommended drill bit angle for various materials. I made this video for those who don't want to go through the full version, which shows sharpening as well as drill bit angles. Many thanks indeed Craig
The Trend drill bit and countersink makes drilling pilot holes and countersinking screws incredibly fast and easy. The bits are compatible with the Trend snappy system and are ¼" hex direct drive shank, which means they can be changed over rapidly. The steel countersinks are TCT with HSS drill bits (you can also get HSS versions) . The bits can be adjusted using the Allen key provided with the set, these can also be used for counterboring.

A look at drill bit grinding and the geometry and hole formation produced by one of the most common metal working tools. The drill. In this video I introduce the Cincinnati Spiropoint drill grinder. A grinder that produces a radially ground drill point thus minimizing the dead area that won't cut in the center of a standard ground drill. The spiral point geometry reduces cutting forces and produces a drill that is less prone to wandering. I take an in depth look at the machine and how this complex task is performed and also go over the setups and how to get the machine to work properly for others that may encounter one of these. This is a long video but it has a lot of good content.Enjoy!

Unh, yeah..I like the way this feel right here
yo...turn me up in the head phones just a lil' bit
yeah..
[50 Cent + (Lloyd Banks)]
There ain't shit in this world deeper than loyalty and love
(Except loyalty and love, between thugs)
For you, I pull up in the whip and spray the whole strip
(For you, I walk up close and lay a nigga's kin)
For you, there ain't a damn thing that I won't do
I'm a Thug, this my way I show, my love for you
(Nigga for you, I get the coke, I'ma turn it into cash)
For you, if we go broke, we gon' rob a nigga ass
(For you, if we get knocked, I'ma have to take the weight
'Cause with a record like yours dogg, you ain't stayin' upstate)
Nigga for you, I kill a whole God damn crew (Why?)
'Cause I know you'd do the same thing too...haha
I ride, you ride for me, my enemies your enemies
How could you not love a Thug like me?
[Chorus]
Would you ride for me? (you ain't even got to ask)
Would you die for me? (nigga, they blast you, they blast me)
Would you cry for me? (shit, when I die I don't cry for me, just keep reppin' Southside for me)
Nigga, you ride for me? (you ain't even got to ask)
Would you die for me? (nigga, they blast you, they blast me)
Would you cry for me? (shit, when I die I don't cry for me, just keep reppin' Southside for me)
[50 Cent + (Lloyd Banks)]
(Nigga, I'm the stem, you the crack
I'm the clip, you the gat
I'm the glock, you the mac
I'm the artist, you the trap
I'm a pen, you the pad
I'm the Dutch, you the bag
I'm the knife, you the stab
I'm the driver, you the Jag)
I'm the ice, you the bezel
I'm grimy, you ghetto
I'm the bow, you the arrow
I'm the shell, you the barrel
I'm a pimp, you a player
I'm dope, you the hustler
I'm a nine, quiet me down, you the muffler
[Chorus]
[Tony Yayo]
You can catch me in public housing, wit' bundles of D
Or in the Santa Monica mountains, bundled up to ski
Since, time is money, I rhyme on the clock
And walk through the strip with a nine in the ox
You seen the ice, you know it's top notch
And when it comes to dice, I'm seeing' shorty to the shot box
Banks stop, guns pop through your tank top
And leave you wet up like a sonar range drop
When I grind, I wear the same thing tomorrow
When you grind, it's Showtime at the Apollo
Damn near every rapper gotta hide sixteen
Well my flow's like a ho that's sixteen
I ran through niggas, dismantled niggas
They mad 'cause they see me in Cancun bitches
But I'm ghetto, straight from the 'hood my nigga
If there's no toothbrush I'ma use my finger
I got so many minks, and so many leathers
The crib is surrounded by animal protesters
I'm a grown man, still livin' like I'm young
With the mind of an old man, full of wisdom
Here the cops come, task force van
Rock so much ice, I'm called Jack Frost man
And while we sippin' on cris', you sippin' backwash man
Your team got heart, but your heart's in my hand
You want sixteen bars, in song format
Or sixteen cars on your mom's doormat...wha
