A sharp one its not the saw you use-- its the blade-- you want to use a carbide tip diamond blade
Diamonds are widely used in the tool industry to tip drill bits and to edge blades that cut tile, stone and rock.
High speed steel, often with a carbide tip
Fans, and propellers differ in exactly how they work, but the same problems occur at very high tip speeds. The fans don't work well if the tip speed is near the speed of sound. So large diameter fans have problems, so do long propeller blades. In fact turbines blades have the same problems, which is why power plants are rarely above 1000 MW.
If there is a tip, it is called culet. Some diamond cuts have no 'tip' or point.You can read more about facets of diamonds and their names, below.
Diamond drill used for drilling hard materials.
When drilling through stone, one should use a tungsten carbide tip. This tip adds much greater stability when drilling, will not go blunt easily or break the stone.

A good drill is important for use on concrete walls, but the bit you use can be just as necessary. A hammer drill with bit that has a carbide or diamond tip would be a good recommendation, remember that using goggles is vital because of the concrete dust.
You measure across the carbide tip as this is the cutting area of the drill. The flutes are there only to bring out the waste materials
