Are you curious about what size a 5mm drill bit is? If so, then you have come to the right place. This article will discuss the size of a 5mm drill bit and provide you with the answer you’re looking for.

What Size is a 5mm Drill Bit?

What Size Is A 5Mm Drill Bit?
A 5mm drill bit is a metric size drill bit that is 0.1969 inches in diameter. It is commonly used for drilling into a variety of materials such as wood, plastic, and metal. This size of drill bit is also referred to as a #7 drill bit in the Imperial measurement system. It is the smallest drill bit size commonly used for hand drilling and is ideal for small hole applications. It is also used in combination with larger drill bits to drill pilot holes for screws.

In the US, drill bit sizes are measured in fractional inch sizes. To determine what size a 5mm drill bit is in inches, divide 5mm by 25.4 (the number of millimeters per inch). This will give you the diameter in inches of 0.1969.

For reference, a 10mm drill bit is 0.3937 inches in diameter, making it approximately double the size of a 5mm drill bit.

What is a 10mm Drill Bit in Inches?

What Is A 10Mm Drill Bit In Inches?

A 10mm drill bit is equivalent to a 0.3937 inches drill bit, or a 3/8 inch drill bit. It is a slightly larger size than the 5mm drill bit, which is equivalent to 0.1968 inches, or 1/8 inch.

What Size Is a Number 3 Drill Bit?

A number 3 drill bit is equivalent to 0.2362 inches, or 3/32 inches. It is a smaller size than the 10mm drill bit.

Here is a list of common drill bit sizes and their corresponding inch equivalents:

  • 5mm = 0.1968 inches, or 1/8 inch
  • 10mm = 0.3937 inches, or 3/8 inch
  • Number 3 = 0.2362 inches, or 3/32 inches

What Size is a Number 3 Drill Bit?

What Size Is A Number 3 Drill Bit?

A number 3 drill bit, or a #3 drill bit, is commonly used for drilling into metals and plastics. It has a diameter of 3/32 inches, which is 2.38mm in metric. It is suitable for drilling into materials such as sheet metal, aluminum, and plastic.

Number Metric Imperial
3 2.38mm 3/32 inches

The #3 drill bit is commonly used in applications such as electrical wiring, plumbing, and fabrication. It is also used for drilling into wood, although it is not as strong as a larger bit. For example, a 14 inch drill bit would be better suited for drilling into wood than a #3 drill bit.

What Number Drill Bit is 14 Inches?

What Number Drill Bit Is 14 Inches?

When it comes to drilling, having the right size drill bit is essential. So, it’s understandable that you want to know the answer to the question “What size is a 5mm drill bit?”

The answer is that a 5mm drill bit is equivalent to a 0.1969 inch drill bit. This is the same as a ⅛ inch or a #31 drill bit.

  • 5mm = 0.1969 inch
  • 0.1969 inch = ⅛ inch
  • ⅛ inch = #31 drill bit

But what if you need to know the size of a 14 inch drill bit? The answer is that a 14 inch drill bit is equivalent to a #2 drill bit. This is because a #2 drill bit is equivalent to 0.2220 inches.

  • 14 inches = 0.2220 inches
  • 0.2220 inches = #2 drill bit

To put it another way, a 5/16 inch drill bit is what is a 516 drill bit equal to. This means that a 5/16 inch drill bit is equivalent to 0.3125 inches.

  • 5/16 inch = 0.3125 inches

Now that you know the answer to the question “What size is a 5mm drill bit?” and “What number drill bit is 14 inches?”, you can confidently choose the right size drill bit for the job!

What is a 5/16 Drill Bit Equal To?

What Is A 5/16 Drill Bit Equal To?

A 5/16 drill bit is equal to 8 mm in metric measurements. To convert drill bit sizes, divide the inches size by 0.3mm, or multiply the metric size by 0.03937.

For example, a 1/4 inch drill bit is equal to 6.35mm, and a 3/8 inch drill bit is equal to 9.53mm. To convert from metric to inch sizes, divide the metric size by 25.4, or multiply the inch size by 0.3mm.

Drill bit sizes are generally stated in fractional inch measurements, such as 1/4 inch, 3/8 inch, and 5/16 inch. However, metric measurements are becoming increasingly popular, with common sizes including 2mm, 4mm, 6mm, 8mm, and 10mm.

It is important to choose the correct drill bit size for the job at hand – using the wrong size drill bit can lead to reduced accuracy and inefficient drilling.

Note: Always ensure that the drill bit is sharp and the correct size for the job. Using the wrong size drill bit can cause damage to the workpiece or injury to the user.

How To Convert Drill Bit Sizes

When it comes to drilling, it’s important to use the right size of drill bit for the job. Drill bit sizes may be measured in either metric or imperial units, and knowing how to convert between the two can be invaluable.

  • Standard Drill Bits – Standard drill bits are measured in fractions of an inch, such as 1/2 inch, 3/8 inch, and so on. To convert these to metric sizes, simply multiply the fractional inch size by 25.4. For example, a 1/2 inch drill bit is 12.7 mm.
  • Metric Drill Bits – Metric drill bits are measured in millimeters, such as 5 mm, 8 mm, and so on. To convert these to imperial sizes, simply divide the millimeter size by 25.4. For example, a 5 mm drill bit is 0.2 inches.
  • Letter Drill Bits – Letter drill bits are a combination of imperial and metric sizes. Letter drill bits are typically measured in fractional inches and are made to fit a specific size. For example, a #5 drill bit is 0.2 inches, or 5 mm.
  • What is a Number Drill? – A number drill is a drill bit that is marked with a number, such as #5, #10, and so on. The number drill is used to indicate the diameter of the drill bit, which is measured in millimeters. For example, a #5 drill bit is 5 mm in diameter.

Knowing how to convert drill bit sizes is essential for anyone who needs to buy the correct size of drill bit for a job. By understanding how to convert between metric and imperial units, you can ensure that you choose the right size of drill bit, every time.

So when someone asks “what does 38 drill mean?”, they are referring to a 5mm drill bit.

What Does 38 Drill Mean?

38 Drill is a metric drill bit size. It is commonly used for drilling into wood, plastic, and other materials. It is slightly larger than a 5mm drill bit.

  • A 38 Drill is 8.1mm in diameter.
  • It is used for making holes in soft materials such as wood and plastic.
  • It is slightly larger than a 5mm drill bit.
  • It is commonly used for making pilot holes for screws and other fasteners.
  • It is also used for drilling into thin sheet metal and other hard materials.

In terms of imperial drill bit sizes, a 38 Drill is equivalent to a #3 drill bit. This means that a 38 Drill is slightly smaller than a 1/8 inch drill bit, but slightly larger than a 5/32 inch drill bit.

When comparing different drill bit sizes, it is important to remember that the size given is not always the exact size of the drill bit. Instead, it is the size of the shank, which is the part of the bit that fits into the drill chuck. Drill bits come in a variety of sizes, shapes, and materials, so it is important to choose the one that best suits your needs.
