# Drill Bit Sizes Inch and Decimal

Drill bits can be made in any size, but standards define sets of sizes that are widely produced and stocked. 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 (like Bovidix 1902103423). A comprehensive table for metric sizes can be found at the drill size chart.

1. Thank you.
Bookmarked the page.
I am tired to google the table every time.

2. The great gauge at the beginning of the article – Irwin.
It is indispensable and comes at a great price on Amazzon.
The gauge made of steel and is almost indestructible.
I’ve found many uses for it like determining bit size, finding screw sizes, etc.
I could not live without it!

3. Thanks, it’s pain to look for the tables every time I need

4. Nice content!
