What is a drill bit size chart and how do you read it?
A drill bit size chart lists drill bit sizes alongside their decimal equivalents so you can match the right bit to a screw, tap, or anchor. You find the size you need in fractional, metric, number, or letter format and read across to the corresponding measurement.
What size systems appear on a drill bit size chart?
Most charts cover four systems: fractional inch sizes, metric millimeter sizes, numbered gauge sizes, and lettered sizes. Each is paired with a decimal equivalent, which lets you compare across systems and pick the closest match when a project specifies one measurement but your bits use another.
How do you choose the right drill bit size for a screw or anchor?
For a pilot hole, choose a bit slightly smaller than the screw shaft so threads grip the material. For anchors, match the bit to the anchor diameter. Use the chart to convert between size systems and reference the decimal equivalent to confirm the closest accurate fit.
