The use of PDC drill bits for drilling has been around for many years. Originally very expensive, the manufacturing techniques have been refined and PDC bits are now far more cost effective, often showing significant economic advantages over tricone, regular drag and percussive bits.
A bench drilling machine is more commonly found in a machine shop than in someone's garage or casual work shop. These machines are large and stationary, often the height of the user if not taller. They require a power source and can sport a variety of different bits to drill a number of different holes.
Drill bits used in the petroleum industry are specially designed and engineered for boring or cutting into rock during oil exploration. They penetrate geological formations until a reservoir trap, or pocket, is reached. This could yield a dry well or a productive oil reserve. Various drill bits are used to get the job done; subsurface temperatures...

I headed into my highly sophisticated drill analysis laboratory (my garage) and scientifically tested four types of 3/8-in. twist bits: a $2.75 high-speed steel bit, a $6 "black oxide" bit, a $7 cobalt bit and a $9.50 titanium bit.
Edit Article Choosing the right drill bit can sometimes be a little difficult. There are many type drill bits for drilling everything from granite and concrete to stainless steels and wood. Know what you will be drilling with requires. Keep the drill bit and the wood cooler during the drilling process.
