Cobalt drill bits are good
For drilling stainless steel, a cobalt or carbide drill bit is recommended due to the hardness of the material. These types of drill bits are specifically designed to withstand the toughness of stainless steel and provide more efficient drilling.
High Speed Steel aka HSS
Drill bits can be made from steel which is a mxture compriing mainly of iron. Many drill bits are coated with a very hard yellowish chemical compound titanium carbide. (made of titanium and carbon)
The drill bits used to drill steel come in different colors. The packaging will indicate what materials can be drilled.
My favorite is simply a high speed steel drill bit, running at SLOW speed (slower than you'd run if drilling mild steel) using green goo as a lubricant called "Westlube" made by Westland Products Company. http://www.westlandproducts.com/ In our operation Westlube changed things from 2-3 holes per drill bit to hundreds of holes per drill bit. For stainless, it's purely magic!

Stainless steel is a corrosion-resistant alloy primarily used in applications where resistance to rust and staining is important, such as in kitchen appliances and cutlery. High-speed steel is a type of tool steel used in cutting tools for machining metals at high speeds, due to its ability to retain hardness at elevated temperatures. Both materials have different compositions and are suited for different applications.
Yes, mortising bits are made for drill press use.
They are used in bits that cut stone or tile.
Stainless steel can be used for manufacturing tablet punch.
In the mining industry, the main types of drill steel used are integral drill steel, tapered drill steel, and extension drill steel. These are essential tools for drilling holes in rock for various mining operations.
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.
