Types of 7/8 Drill Bits

There are several types of 7/8 drill bits available, each designed for specific applications:

• High-Speed Steel (HSS): This is the most common type of 7/8 drill bit, made from high-speed steel for durability and heat resistance.

• Carbon Steel: Carbon steel bits are less expensive than HSS bits but are less durable and may not be suitable for high-temperature applications.

• Black Oxide: Black oxide-coated bits provide increased durability and resistance to rust and corrosion.

• Carbide: Carbide bits are extremely durable and can handle high-temperature applications, but they are more expensive than other types.

Choosing the Right 7/8 Drill Bit

When selecting a 7/8 drill bit, consider the following factors:

• Material: Choose a bit made from the appropriate material for the material you’ll be drilling.

• Coating: Consider a coated bit if you need increased durability
