How do you supposed to know exactly which size you need? There are other methods that can help you pick the correct sized bit other than looking at the size chart. All you have to do is to follow our suggestion below: Method 1 - Take the screw that you want to use after drilling and place it next to the drill bit. To measure the diameter of a drill bit, it's best to measure the cutting edge rather than the shank (the shank is the part that is held by the drill chuck). To get an accurate measurement, use Vernier callipers, but be aware that depending on the quality of the drill bit, there could be a tolerance error of between 5 and 15 thousandths of a unit.

This handy pilot hole size chart should help you. Why Pre-Drill a Pilot Hole? Since screws have a sharp end to them, why is it necessary to pre-drill holes to accommodate the fastener? It is true that the self-tapping screws can easily penetrate into softwood with the help of a drill driver or an impact driver. There are a couple different methods for choosing the right drill bit size: eyeballing and numerical. Eyeballing the drill bit The first method involves eyeballing, or looking at the drill bit in front of the screw. Drill Bit Size Chart The drill bit size chart provides equivalent sizes for letter, metric, wire gauge, and fractional drill bit sizes, allowing the user to select the correct drill bit for their project. Drill Bit Size Identifiers Inch Letter Metric Wire Gauge Measure drill bit sizes with these identifiers. Drill/tap identifier includes a tap size conversion chart.

The root diameter is the distance from one side of the screw head to the other, not including the threads. For a #8 wood screw, the root diameter is 0.164 inches.
The drill size chart is a table list standard size drill bits in several measurement systems, including fractional, metric, wire gauge number, and letter. Fractional sizes are measured in inches, while metric sizes are measured in millimeters. The wire gauge and letter systems refer to tool diameters that increase as the wire gauge decreases. ANSI and ISO Twist drill size chart Fractional and Metric Sizes per. ANSI/ASME B94.11M-1993 below are the standard size drill bits used and readily available in industry. Fractional sizes are measured in inches, while metric sizes are measured in millimeters. The drill size chart contains twist drill data for up to 1.0 inches in diameter.

First things first. If you were to look at the most all encompassing collection of multi-purpose, twist-type bits, how many drill bit sizes would there be? Well, if you base your answer on how many size holes there are in the world, then there would be infinite amount of bits! First Method First, pick the screw you will use, and the next task is to pick a drill bit similar in size or the closest size. To determine the size measurement of a drill bit for screws, just line them end to end and check whether the bit has the same width as one of the screws, excluding its threads.
