Depending on the quality - Poor quality cheap drills may be ground with a groove down each side and then heated up and twisted. the end is then sharpened.
Modern more upmarket drills are ground as they rotate to produce the spiral Flute. the end is then sharpened.
The drills are hardened and tempered to make them hard enough to drill metal etc.
Masonry drills have a tough carbide tip brazed onto the end to resist the abrasive effects of the brick / concrete dust as they drill

∙ 13y agoDrill bits are made from steel. Specialized bits have enhancements to the steel to increase hardness or maintain sharpness. Magnesium, tungsten, titanium, chromium, vanadium, and molybdenum are elements added to steel for special purpose uses.
A few types of extremely specialized bits don't use steel. For example, a bit designed to drill through glass will have a cutting edge of an abrasive such as diamond chips.

∙ 12y agoMost common drill bits are made out of an alloy called "high speed" steel. They have great hardness (will hold an edge longer) but are also somewhat brittle. This is not normally a problem until you get down to the very small sizes, like 1/16 inch - then they break like potato chips.

How do you organize drill bit equipment?
When I had a large shop I used to have 3 racks on the wall behind the bench drill press, one for standard drill bits, one for specialist drill bits and one for hole saws, Forstner bits and fly bits.
