Having the ideal drill little bit sizes accessible for your specific fixing or building task is essential for any type of experienced carpenter or weekend-DIY’ er.
Knowing just what dimension you require to use for the opening you’re making is additionally vital.
It might not be totally apparent in the beginning look.
Several times, we’re just trying to find out the different sizes readily available if you’re dealing with statistics dimensions (measured in millimeters) versus criterion or empirical values (our familiar fractional inch variety).
TIP: Have a look at our complete drill graph below for a quick reference to locate all drill size equivalents.
Finally, obtaining the ideal dimension drill bit embeded in your higher device “breast” will arm you for the different kinds of jobs you’re doing.
We’ll go over these thoroughly in this write-up.

The amount of Drill Little bit Sizes Exist?
First things first. If you were to look at the most all incorporating collection of multi-purpose, twist-type little bits, the amount of drill bit sizes would certainly there be?
Well, if you base your answer on exactly how lots of dimension holes there are in the globe, then there would be unlimited quantity of little bits!
The good news is, we can narrow it down a bit to some basic sized little bits and holes.
As an example, allow’s look at the most typical applications:
Everyday home repair and building and construction projects, leisure activity, marine, farming, woodworking, metal working, airplane, crafts as well as arts, commercial building tasks, machinery and even more.
You obtain the factor!
For every particular application area, you’re mosting likely to simply see a couple of lots approximately pertinent drill bit dimensions.
As a matter of fact, many good sets include anywhere from 12-30 items of typical drill bit sizes. (And far more when you consider different types of little bits).
Using our drill chart that complies with below, you’ll get a suggestion of just exactly how numerous sizes there are!
Sorts Of Drill Little Bits
Different little bit types exist for a variety of applications, and also in particular what product you’re piercing into.
For the sake of simplicity, allow’s consider a standard multi-purpose set.
One that might offer any of the above discussed self-controls well.
State, for instance, a regular 29-piece collection. In the adhering to drill little bit chart are the normal fractional sizes this sort of collection would include.
This would usually put on lots of drill bit types, such as black oxide, titanium, carbide, high-speed steel as well as masonry (concrete), to name a few.
Basic, twist-type drill bit dimensions (fractional):
- 1/16 ″
- 5/64 ″
- 3/32 ″
- 7/64 ″
- 1/8 ″
- 9/64 ″
– 5/32 ″.
- 11/64 ″
- 3/16 ″
- 13/64 ″
- 7/32 ″
- 15/64 ″
- 1/4 ″
- 17/64 ″
- 9/32 ″
- 19/64 ″
- 5/16 ″
- 21/64 ″
– 11/32 ″.
- 23/64 ″
- 3/8 ″
- 25/64 ″
- 13/32 ″
- 27/64 ″
- 7/16 ″
- 29/64 ″
- 15/32 ″
- 31/64 ″
- 1/2 ″
There are without a doubt bigger collections. Specialty fasteners occasionally ask for a dimension that would be taken into consideration uncommon.
Collections with also more varying drill little bit dimensions would certainly include sizes smaller than 1/16 ″ or bigger than 1-1/2 ″.
In in between in these big little and big dimensions are every comparable little bit size known to “male”, so you constantly have the specific dimension needed relying on what you’re project is asking for.
Below would be the standard drill bit sizes for spade bits (13-pieces):
– 1/4 ″, 3/8 ″, 1/2 ″, 9/16 ″, 5/8 ″, 11/16 ″, 3/4 ″, 7/8 ″, 1 ″, 1-1/8 ″, 1-1/4 ″, 1-3/8 ″ as well as 1-1/2 ″
And also dimensions for action drill bits:
– Range from 1/8 ″ to 1-3/8 ″
If you need drill little bit dimensions that are bigger than 1 ″, you can commonly utilize a spade little bit for timber and also various other soft materials.
To prevent break-outs as well as chipping, you can stick to bigger round-shank types.
or shank bits however, you’ll usually require a
1/2; 33/64; 17/32; 35/64; 9/16; 37/64; 19/32; 39/64; 5/8; 41/64; 21/32; 43/64; 11/16; 45/64; 23/32; 47/64; 3/4; 49/64; 25/32; 51/64; 13/16; 53/64; 27/32; 55/64; 7/8; 57/64; 29/32; 59/64; 15/16; 61/64; 31/32; 63/64; 1; 1-1/8; 1-1/4; 1-3/8; 1-1/2
Exactly how Do you recognize What Dimension Drill Bits You Required?
If you’re a typical weekend-warrior, you’ve probably gazed at a screw or bolt for a few moments and also wondered what size drill bit you would require.
Gradually, you obtain so that you can actually eye-ball it and also make an enlightened guess.
However if you’re looking at a less typical drill little bit size, you need a help to help you.
A drill bit dimension hole card can be extremely handy for this. A simple plastic drill graph sheet with excellent round holes and markings on it lets you do a number of points.
Initially, you can size screws simply by putting them right into an opening then reviewing the noting.
You can likewise size drill bits by pressing them via openings.
This is particularly handy if you can not review the engraved dimension markings on the little bits.
It’s likewise practical to locate the replacement little bit dimension to cross over in between basic and statistics dimensions.
Exactly how to convert and Find Equivalent Bit Sizes
You can use the drill graph that follows this area to assist transform dimensions, or you can do the math on your own.
To make things simply a bit a lot more challenging, not all drill bit sizes remain in north american fractional measurements.
The statistics system is made use of to define statistics drill little bit dimensions also.
If you have this set, or need to match, simply utilize an easy formula to convert from statistics to fractional inches, as well as the other way around:
- Converting from millimeters into inches: Increase by 0.039
- Transforming from inches to millimeters: Multiply by 25.4

As guaranteed, right here are a few drill bit graphes to aid you rapidly transform all basic drill bit dimensions to their matching dimensions.
If you’re touching holes you’re pre-drilling tools you can look into our faucet drill graph for particular size conversions.
Drill Graph for Gauge 47-96 (smallest to largest)
This graph details the North American drill scale sizes and transforms them to their decimal matching in both inches and also millimeters for statistics sizes.
Keep in mind: Below these charts is the basic fractional dimension conversion drill chart.
Drill Graph for Gauge 1-46 (smallest to biggest)
This graph rounds out the second fifty percent of these number gauge sizes down to # 1, which is the largest drill bit dimension.
Pierce Chart for Scale Letters (smallest to largest)

The following drill graph covers the smallest conventional drill diameter dimension of 1/64 to 21/32 as well as provides you the equivalent sizes in both decimal inches and also millimeters.
This final drill graph covers the conventional little bit sizes from 43/64 to 1 27/64.
More Regarding Drill Bit Establishes and also Sizing
Some various other useful info to help you in your knowledge of drill bit dimensions:
Fractional sizing usages entire, fifty percent (1/2), quarter (1/4), 8th (1/8), sixteenths (1/16) and sixty-forths (1/64).
As an example, something just above 31/64 ″ would certainly be a half-inch, as well as anything over 63/64 ″ would certainly be a 1-inch drill bit dimension.
