		+	===HSS===
		+	This is the benchmark material for drill bits.
		+	===Cobalt steel===
		+	Better heat, wear, and lifetime than HSS.
		+	===Carbide===
		+	Harder and stronger, but expensive and brittle.
		+	==Coating==
		+	Coatings affect price, corrosion resistance, lifetime, hardness, heat, and chip evacuation.
		+	===Black oxide===
		+	Inexpensive coating that increases corrosion resistance and life.
		+	===Titanium===
		+	Multiple types of titanium based coatings exist. They are superior to black oxide but more costly.
