High-Speed Steel Multidiameter Drill Bits
Titanium Nitride (TiN)

Steps with progressively larger diameters let you drill a range of sizes with one bit. Also known as step drills.
Titanium-nitride (TiN) coated drill bits last longer and can drill at higher speeds than uncoated drill bits and black-oxide drill bits.
