Twist Drill Bits:

• Purpose: General drilling in metal.
• Use: Most common drill bit for metalworking, suitable for a variety of metals.
• Feature: Cylindrical shape with a spiral groove (flute); made from high-speed steel (HSS) or cobalt for durability.

Cobalt Drill Bits:

• Purpose: Drill hard metals like stainless steel.
• Use: Ideal for drilling through tough alloys and stainless steel.
• Feature: Made of a solid cobalt alloy, offering high resistance to heat and wear.

Carbide Drill Bits:

• Purpose: For precision drilling in hard materials.
• Use: Used in CNC machining for drilling tough metals and for achieving precise tolerances.
• Feature: Extremely hard and maintain a sharp edge longer than HSS or cobalt bits.

Core Drill Bits:

• Purpose: Enlarge existing holes in metal.
• Use: Used for enlarging or refining holes made by another drill bit.
• Feature: Typically hollow, removing less material and requiring less power.
