## How can you tell the size of a drill bit?

Typical drill bits have markings somewhere on the shank above the threads. It’s small, but it usually has the drill-bit diameter stamped into the metal; the number is written in fractions. For example, the markings may read: 1/4-inch, 3/6-inch or 25/32.

## How do you know what drill bit to use for a screw?

Almost all drill bits have their dimensions labeled on the actual bit. For screws, you’ll need to find the box or bag that they came in. For a size 2 screw, use a 1/16 bit. For a size 9 screw, use a 9/64 bit.

## What can I use instead of a 5’8 drill bit?

If you break it down to 16th’s, 5/8ths is 10/16ths. So the next size larger would be 11/16th’s. If you want to stay in 1/8ths, than obviously it’s 6/8ths or 3/4″. If you break it down to 16th’s, 5/8ths is 10/16ths.

## How big is the smallest letter gauge drill?

This chart shows the diameters of letter gauge drills size A (the smallest) to size Z (the largest).

## What do the numbers mean on a drill?

As mentioned at the beginning of the article, the numbers on a drill represent the amount of torque the tool can apply to an object (such as a screw) or for hole drilling. The numbers usually range from 1 to 20 (or more) with 1 representing the least amount of torque and 20, the greatest. Some drills can have a range of over 20.

## What does the hammer symbol on a drill mean?

When you drive screws the torque setting is important because you don’t want to overdrive the screw and bury it into the material. Hammer Action Mode The symbol that looks like a hammer signifies the hammer action mode or the hammer drill settings.

## What is a Type F drill bit?

“F” Solid Carbide Drill Bit. Designed for drilling abrasive materials when drilling accuracy must be maintained. Can be used in high temperature drilling applications. Used on materials such as cast iron, non-ferrous alloys, high silicon aluminum, copper, plastics , bronze, hard rubber, plexiglass, and other similar materials.

## What is the standard size of a drill bit?

Another size related feature to focus on is the size of the drill bit, as we mentioned earlier. The most common drill bit sizes are 1/16 to 1/4″ and most large sets will also include increments up to 1/2″ thick.

## How big is a drill bit?

Drill bit sizes are written down on paper and etched onto bits as irreducible fractions. So, instead of 78/64 inch, or 1 14/64 inch, the size is noted as 1 7/32 inch . Below is a chart providing the decimal-fraction equivalents that are most relevant to fractional-inch drill bit sizes (that is, 0 to 1 by 64ths).

## What are the sizes of drill bits?

Drill Bit Lengths Jobber-length drill bits are the most common, with a length somewhere between 9 to 14 times the diameter. Screw-machine-length drills arethe shortest available standard sized bits. Aircraft-length drills are extended length drill bits that are manufactured in fixed length such as 4, 6, 8, 12, 18, 24-inch bits, rather than proportional lengths.
