3/17/2024 0 Comments Drill bit sizing chart![]() You can measure 1/16″ to 1/2″ range of drill bits using that gauge. As for me I use this gauge to identify the drill bit size in inches and millimeters quickly. The table below will introduce you to the fractions and decimals of inches in mm. So we have to interchange the metric units and imperial units. Inches are really popular in the USA but, beyond that, mostly used SI units. You can multiply by 25.4 of inches value when you convert that to mm.Įx – 0.5 inches = 1/2″ = 0.5 inches × 25.4 = 12.7mm When you measure drill bit size in inches, you can convert it into mm using this method. When the drill bit diameter is available in mm, it can be converted into inches easily. Fractionĭrill Bit Sizes in inches and mm table Drill Bit Size Conversion Methods 1.

You can see fractions, inches, and mm values for each drill bit size here. Selector charts to help you find the right Hilti product for your application. ![]() Choose from our selection of drill bit charts in a wide range of styles and sizes. Drill/tap identifier includes a tap size conversion chart. How to Convert Drill Bit Inches to mm?īy following the above method, this table has been prepared with available drill bit sizes. Measure drill bit sizes with these identifiers. Strap on your tool belt, it’s time to drill with confidence. It’s not just about power, it’s about precision, and this chart’s got your back. Remember, size matters and this chart is your roadmap to ensure you’ve always got the right drill bit at hand. Say goodbye to guesswork, whether you’re dealing with fractions of an inch, the trusty millimeter, or need to convert between the two. Hole saw kits are popular option since they include many of the most commonly used sizes and are almost always a better value than purchasing individual pieces. This bad boy allows you to effortlessly navigate between ANSI, metric, and ISO measurements. Like drill bits, there are a large number of different hole saw sizes available although you’ll likely to only ever need to use a handful. So here’s your ultimate drill bit size chart, an essential piece of kit that’s gonna be your go-to resource when dealing with different standards. And when it comes to drilling, precision is the name of the game. Defined in the ANSI B94.11M-1979 Standards, the fractional inch drill bit sizes start from 1/64 inch and scale up all the way to 1inch with 1/64inch increments. ![]() You know how vital it is to have the right tool for the job. For instance, a 10mm drill bit would be approximately 0.394 inches. So, to convert a metric drill bit size to inches, you would divide the size in millimeters by 25.4. The drill bit size chart is an important part of the drilling process, first step is choosing a drill bit size chart. Here is an expanded drill bit sizes chart that includes both metric and imperial measurements, ranging from 0.05mm to 38mm: Drill Bit Size (mm) Drill Bit Size (inch) 0.05: 0.0020: 0.1: 0.0039: 0. As for converting ISO (metric) to inches, a conversion factor of 25.4 is used, as there are 25.4 millimeters in one inch. When it comes to the selection of drill bit sizes and tap sizes, there are standard drill and tap size chart for reference. Metric drill bit sizes offer a similarly wide array of sizes for all kinds of applications. ![]() Metric drill bit sizes are typically given in millimeters (mm), incrementing in 0.1mm steps for smaller sizes and in 0.5mm steps for larger sizes. On the other hand, metric drill bit sizes, largely used outside the United States, are based on the International System of Units (SI) measurements. This provides a broad spectrum of drill bit sizes to cater to various applications. This chart shows the diameters of letter gauge drills size A (the smallest) to size Z (the largest). The system also includes a number series (from size 80, the smallest, to size 1) and a letter series (from A to Z), both used for diameters smaller than 1/4 inch. Drill bit sizes under ANSI are given in fractions of an inch, typically starting at 1/64 inch, then incrementing in 1/64 inch steps for smaller sizes, and up to larger sizes such as 1/2 inch, 1 inch, and so on. American National Standards Institute (ANSI) drill bit sizes are used predominantly in the United States and utilize the Imperial measurement system.
