## Comparison of Different Drill Bits

The most common drill bit size is 5/16 inch. It is used for drilling through wood, plastic, and aluminum. But depending on the material and the job at hand, there are other drill bit sizes that may be more suitable.

Twist drill bits are the most commonly used drill bits and are available in various sizes, ranging from 1/16 inch to 1/2 inch. They are made from high-speed steel and have a spiral shape with two parallel cutting edges. These drill bits are suitable for drilling through wood, plastic, and metal.

Masonry drill bits are designed for use on hard materials like concrete, brick, and stone. They are usually made from carbide and have a tapered tip with a spiral flute. The tip is designed to cut through the material, while the flute allows for the removal of debris.

Spade drill bits are designed for use on softer materials like wood and plastic. They have a flat end and are available in various sizes. They are suitable for making large diameter holes and are often used in construction.

Screw extractor drill bits are used to remove screws that have become stuck in surfaces. They are made from high-speed steel and have a spiral flute. The tip is designed to grip onto the screw head and allow for easy removal.

Countersink drill bits are used to create a beveled edge on the surface of a material. They are available in various sizes and are made from high-speed steel. The tip is designed to cut into the material, while the flute allows for the removal of debris.

When choosing the right drill bit for the job, it is important to consider the material and the size of the hole that needs to be drilled. Different drill bit sizes are suitable for different materials and applications, so it is important to select the right one for the job.

## Commonly Used Drill Bit Sizes and Equivalents

The drill bit size 5/16″ is equivalent to 8.0mm or 0.3125″. This size of drill bit is commonly used for a variety of drilling tasks, including drilling into wood, plastic, metal, and masonry. It is also used to make pilot holes in order to accommodate larger drill bits.

When working with different materials, it’s important to use the right type of drill bit. For example, a high-speed steel drill bit is ideal for drilling into metal, whereas a carbide-tipped drill bit is better suited for drilling into masonry or concrete.

The following table provides a list of commonly used drill bit sizes and their equivalents:

Drill Bit Size (in) Equivalent (mm)
1/16″ 1.5875mm
5/64″ 2.381mm
3/32″ 2.38mm
7/64″ 2.78mm
1/8″ 3.175mm
9/64″ 3.571mm
5/16″ 8.0mm
11/64″ 4.366mm
3/16″ 4.762mm
13/64″ 5.15mm
7/32″ 5.556mm
15/64″ 5.95mm
1/4″ 6.35mm
17/64″ 6.745mm
9/32″ 7.14mm
19/64″ 7.535mm

When drilling into masonry, it’s best to use a masonry bit that’s the same size as the drill bit you’re using. For example, if you’re using a 5/16″ drill bit, you should use a 5/16″ masonry bit.

It’s also important to choose the right drill bit for the job. For example, if you’re drilling into metal, you’ll need a cobalt or titanium drill bit. If you’re drilling into wood, a brad point or spade bit will do the job. And for drilling into plastic, you’ll need a plastic drill bit.

No matter what type of drilling job you’re tackling, it’s important to have the right drill bit on hand. Knowing the equivalent size of 5/16″ and other commonly used drill bit sizes can ensure that you have the right tool for the job.
