6 Common Types of Drill Bits

Choosing the right type of drill bit is important. Drills, of course, are used to create threaded holes in objects. Before driving a bolt or screw into an object, you may want to create a threaded hole in it. A drill will allow you to create threaded holes such as this. You'll need to use the right type of drill bit, however. Here are six common types of drill bits.

#1) Twist

Twist is one of the most common types of drill bits. They feature a "twisted" design that allows them to dig through most materials. You can use a twist drill bit to create threaded holes in wood, metal and even plastic.

#2) Brad Point

There are brad point drill bits. You can use them to create super-clean holes. Brad point drill bits won't splinter wood, nor will they create jagged edges or sides. Thanks to their unique design, they can create clean and uniform threaded holes.

#3) Spade

When researching the different types of drill bits, you may come across spade. What are spade drill bits exactly? They are large, flat drill bits that are designed for drilling threaded holes in wood. They have a central point and two cutting edges on the sides that remove wood quickly and cleanly. Spade drill bits are available in a range of sizes and are ideal for drilling holes for pipes or cables.

#4) Masonry

We can't talk about drill bits without mentioning masonry. As the name suggests, masonry drill bits are used to create threaded holes in masonry, including concrete and brick. They are typically made of heavy-duty tungsten carbide, which is a hard and durable material that can withstand the high temperatures and pressures generated when drilling through masonry materials.

#5) Auger

There are also auger drill bits. Auger drill bits are designed for drilling deep, narrow threaded holes in wood. They have a spiral shape that removes wood quickly and efficiently. You can use them to create threaded holes for dowels or other types of fasteners in wooden objects.

#6) Step

Last but not least, there are step drill bits. Step drill bits are characterized by the use of a cone-shaped tip with multiple steps that increase in size. You can use them to create threaded holes of specific sizes in a variety of materials. Step drill bits simply offer a higher level of precision, which isn't found with other types of drill bits.
