What is the closest standard size to 6mm?Ġ:482:17Quick way to determine right size drill bit – YouTubeYouTubeStart of suggested clipEnd of suggested clipSo it’s just a quick tip. The typical sizes of drill bit point angles are 115° or 118° (degrees). Lengths of up to 18″ or more may be needed. This is especially useful when creating a hole from the outside of your house to the interior. Other contractors will use masonry bits in their hammer drills to bore through materials such as concrete, stones and bricks. Carbide drill bits enable greater cutting speed while maintaining a high-quality finish than cobalt drill bits, enhancing manufacturing throughput. This leads to longer tool life, often offsetting the cost difference. Which drill bit is stronger carbide or cobalt?Ĭarbide drill bits are generally more expensive than cobalt but can withstand higher temperatures and have greater wear resistance. Bit sizes are usually printed on the shank of the drill bit. If necessary, bigger bits (5/16-inch, 3/8-inch, 7/16-inch, and 1/2-inch) can be added. ![]() Some applications require specific drill bit sizes, but a bit set with sizes ranging from 1/16 inch to 1/4 inch can cover a wide range of tasks around the house and workshop. How Many Inches is 6 mm? 6 mm equals 0.236 inches, or there are 0.236 inches in 6 millimeters.

Plus, the box at top lets you quickly search to sizes near that one. With the checkboxes at the top, you can limit what you’re seeing to exactly what you want. That’s why I built a Drill Size Chart into my G-Wizard software: I prefer software because it can search, copy values to where they’re needed, and generally save you effort. The thing about charts, especially wall charts, is they’re convenient for some things, but unwieldy for others. ![]() Check out our article on tap drill sizes to find a much better way. Don’t just pick the first tap drill size you come across, not even the one in our Drill Chart below. While it may seem logical that most holes are nice round numbers in size, certain operations benefit from a lot of intermediate sizes. Number and Letter Sizes are in common use in the US, and to a lesser extent the UK (rapidly moving to metric), but are no longer in use for most of the rest of the world which has gone fully metric. Letter Sizes are Imperial drill bit sizes designated A (smallest) to Z (largest). The numbered sizes are based on but unfortunately are not identical to the Stubs Steel Wire Gauge, which originated in 19th century Great Britain. In practice, you will seldom see number sizes past #80. The ASME B94.11M twist drill standard establishes number drill bit sizes from size 1 to 97. Number Drill Bit Sizes & Letter Drill Bit Sizes Decimal Equivalence ChartĪ good drill size chart can also be used as a handy decimal equivalence chart as well as to convert decimal sizes to metric. After that they run in 1/32″ increments up to 2 1/4″, then in 1/16″ increments to 3″, 1/8″ increments to 3 1/4 inches, then there’s a 3 1/2″ size. Fractional-Inch Drill Bit Sizesįractional-inch sizes are in common use in the US and generally run from 1/64 inch up to 1 3/4 inch in 1/64″ increments. There are also Reynard Series of preferred metric drill sizes. So for N = 2, it’s 2 – 0.1, etc.įrom 1 through 2.95mm, using N from 10 through 29, we get:įor 3 through 13.9mm, with N from 30 to 139:įor 14 through 25mm, and N from 14 through 25: Standard metric lengths (from standards like BS 32*) define metric drill bit sizes using this system:įor 0.2 to 0.98mm, sizes use N from 2 through 9: It covers decimal, fractions, numbered drill bits, letter drill sizes, metric drill bits, and probably a few more things I forgot to mention.įor more on twist drills in general, see our twist drill article for all the different types and tips for holemaking with them. It’s very convenient to have a drill chart around with bit sizes, so we thought we’d put one here for you. ![]()
