Understanding F Drill Bit Sizes

Understanding F Drill Bit Sizes
Drill bits are used to bore holes into surfaces, such as wood, metal and plastic. They come in various sizes, and one of the most common drill bit systems is the F system. To accurately determine the size of an F drill bit, the drill bit measurement system must be understood.

Drill Bit Measurement System

The drill bit measurement system is based on two parameters: the diameter of the drill bit and the length of the bit. The diameter is defined in fractions of an inch and the length is defined in inches. Therefore, an F drill bit is marked with two numbers, such as 7/16″ and 4″. This means that the diameter of the drill bit is 7/16″ and the length of the bit is 4″.

Standard F Drill Bit Sizes

The most common sizes of F drill bits are 1/8″, 3/16″, 1/4″, 5/16″, 3/8″, 7/16″ and 1/2″. These sizes are used for a variety of drilling applications and are widely available. To determine the size of an F drill bit, measure the diameter and length of the bit and compare the measurements to the standard F drill bit sizes.
Knowing what size is an F drill bit is important for any drilling job. It is important to select the correct drill bit size to ensure that the job is done properly and safely. Always consult a professional if you are unsure of what size drill bit to use.

Selecting an F Drill Bit

Selecting An F Drill Bit

Consider Material

The material you are drilling into is the most important factor in choosing an F drill bit. Metal surfaces require high-speed steel (HSS) drill bits, while wood and softer materials are better suited for brad point bits, which will not wander when beginning to drill the surface.

Consider Hole Size

The size of the hole is also important for selecting the right F drill bit. A standard F drill bit is generally 3/16 of an inch in diameter, but different sizes can range from 1/8 of an inch to 1/4 of an inch. When selecting the size of the bit, it is important to consider whether your hole needs to be slightly bigger or smaller than the standard size.
