Letter gauge drill sizes are used primarily in North American with A starting with the smallest size working 26 size increments to Z. The following drill chart covers the smallest standard drill diameter size of strong>1/64 to 21/32 and gives you the equivalent sizes in both decimal inches and millimeters.

## What size is a 78/64 drill bit?

Drill bit sizes are written 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).

## How do you find the decimal equivalent of a drill bit?

Drill Bit Decimal Equivalency Chart. For exact decimal equivalent, multiply mm times .03937. For exact mm equivalent, multiply decimal times 25.4.

## Are there any 49/250 drill bits that are equivalent to a 9?

However, standard fractional drill bits come in intervals of 1/64 inches. Therefore, there are no standard fractional drill bits that are the exact 49/250 fraction that the #9 drill bit is. To find the closest gauge wire #9 drill bit equivalent in fractional inches, we round 49/250 up and down to 1/64 accuracy to get the following:

## What is a carbide drill bit?

Carbide Drill Bits for Hardened Steel. Harder, stronger, and more wear resistant than carbide-tipped steel, solid-carbide bits maintain their sharp edges longer. They require rigid toolholding to prevent breakage and should not be used in hand-held drilling applications.

## What are slow spiral drill bits?

Drill Bits for Aluminum, Brass, and Bronze. Because softer metal, like aluminum, brass, and bronze, can clog a bit, the flutes on these bits lift chips out of the hole. Also known as slow-spiral drill bits.

## What are the flutes on a jobber’s bit?

The short flutes on these jobbers’ -length bits provide increased rigidity for drilling straighter holes.

## What is the difference between solid carbide and cobalt?

Harder, stronger, and more wear resistant than cobalt steel, solid-carbide bits maintain their sharp edges longer. They require rigid toolholding to prevent breakage and should not be used in hand-held drilling applications.

## What is cobalt steel?

Cobalt steel bits are heat resistant and maintain their sharp edges when drilling hard material. They are for use in both hand-held drilling and machine-tool applications.

## Why do you need holes in a CNC machine?

Holes in these bits allow coolant to be run through the tool for more efficient chip evacuation. Use them in CNC machines with coolant-through technology.

## What size shaft can access screws in narrow recessed holes?

The small -diameter shaft can access screws in narrow recessed holes.

## What is the largest drill bit size?

This chart rounds out the second half of these number gauge sizes down to #1, which is the largest drill bit size.

## How Do You Know What Size Drill Bits You Need?

If you’re an average weekend-warrior, you’ve probably stared at a screw or bolt for a few moments and wondered what size drill bit you would need.

## What is the typical drill bit angle?

The typical sizes of drill bit point angles are 115° or 118° (degrees).

## What size drill is used for letter gauge?

Letter gauge drill sizes are used primarily in North American with A starting with the smallest size working 26 size increments to Z.

## How to size screws?

First, you can size screws simply by inserting them into a hole then reading the marking.

## Can we narrow down a bit?

Thankfully, we can narrow it down a bit to some standard sized holes and bits.

## Can you use drill chart to convert sizes?

You can use the drill chart that follows this section to help convert sizes, or you can do the math yourself.

## What is the measurement of drill bits?

Drill bits are available in different materials, lengths, and diameters. Most are measured by the metric units and in the USA it’s imperial units. Drill bit diameter is the most important factor in the drilling process and it should know precisely as much as possible to sharpen or tolerate the diameter.

## How many mm is 1 inch?

1 inch is equal to 25.4 mm. By dividing the inches other fractions are introduced. Inches are really popular in the USA but beyond that mostly used the SI units. So we have to interchange the metric units and imperial units.

## What drill bit makes a hole smaller than a 9?

Caution: Due to rounding, a 3/16 drill bit will make the hole smaller than a #9 drill bit and a 13/64 drill bit will make the hole larger than a #9 drill bit. Below we converted the fractions to decimals so you can compare more easily:

## How many mm is a #9 drill bit?

There are 25.4 millimeters (mm) in an inch. Thus, to convert a #9 drill bit to millimeters, you simply multiply the decimal inches by 25.4 like so: 0.1960 inches x 25.4. = 4.9784 mm. Drill Bit Size Chart.

## What is 0.1960 as a fraction?

0.1960 decimal as a fraction is 49/250. However, standard fractional drill bits come in intervals of 1/64 inches. Therefore, there are no standard fractional drill bits that are the exact 49/250 fraction that the #9 drill bit is.

## What is a 27/64″ drill bit?

Machinists generally truncate the decimals after thousandths; for example, a 27/64″ drill bit may be referred to in shop-floor speech as a “four-twenty-one drill”.) Charts like this, printed at poster size, are widely posted on machine shop walls for handy reference by machinists as they work.

## What size drill bits are available?

The price and availability of particular size bits does not change uniformly across the size range. Bits at size increments of 1 mm are most commonly available, and lowest price. Sets of bits in 1 mm increments might be found on a market stall. In 0.5 mm increments, any hardware store. In 0.1 mm increments, any engineers’ store. Sets are not commonly available in smaller size increments, except for drill bits below 1 mm diameter. Drill bits of the less routinely used sizes, such as 2.55 mm, would have to be ordered from a specialist drill bit supplier. This subsetting of standard sizes is in contrast to general practice with number gauge drill bits, where it is rare to find a set on the market which does not contain every gauge.

## What size drill bit should I use for straight shank?

ANSI B94.11M-1979 sets size standards for jobber-length straight-shank twist drill bits from 1/64 inch through 1 inch in 1/64 inch increments. For Morse taper -shank drill bits, the standard continues in 1/64 inch increments up to 1¾ inch, then 1/32 inch increments up to 2¼ inch, 1/16 inch increments up to 3 inches, 1/8 inch increments up to 3¼ inches, and a single 1/4 inch increment to 3½ inches. One aspect of this method of sizing is that the size increment between drill bits becomes larger as bit sizes get smaller: 100% for the step from 1/64 to 1/32, but a much smaller percentage between 1 47/64 and 1 3/4.

## What is the most common drill bit size?

In the U.S., fractional inch and gauge drill bit sizes are in common use. In nearly all other countries, metric drill bit sizes are most common, and all others are anachronisms or are reserved for dealing with designs from the US. The British Standards on replacing gauge size drill bits with metric size s in the UK was first published in 1959.

## What is fractional drill bit?

Fractional-inch drill bit sizes. Fractional drill bit set by Craftsman. Fractional-inch drill bit sizes are still in common use in the United States and in any factory (around the globe) that makes inch-sized products for the U.S. market.

## What is a jobber drill?

The term jobber refers to a wholesale distributor —a person or company that buys from manufacturers and sells to retailers. Manufacturers producing drill bits “for the trade” (as opposed to for specialized machining applications with particular length and design requirements) made ones of medium length suitable for a wide variety of jobs, because that was the type most desirable for general distribution. Thus, at the time that the name of jobber-length drill bits became common, it reflected the same concept that names like general-purpose and multipurpose reflect.

## What is the tolerance for smaller drill bits?

In smaller sizes, bits are available in smaller diameter increments. This reflects both the smaller drilled hole diameter tolerance possible on smaller holes and the wishes of designers to have drill bit sizes available within at most 10% of an arbitrary hole size.
