When creating clearance holes or tapping threads, you can’t simply guess which drill bit is right for the job. You need to find the specific one that meets your needs. Luckily, Drill Bit Warehouse has you covered with our drill sizing chart.
Use the drill bit chart below to determine which bit matches the hole diameter you must drill. If you want to drill a hole with a diameter of 0.3580”, the chart will tell you that a Letter T drill bit is exactly what you’re looking for.
However, if you are measuring your hole diameter using millimeters and using imperial drill bits, Drill Bit Warehouse can assist you with our metric conversion chart. It will help you find the closest match in inches that you need. Let us guide you in finding the right bit with our drill sizing chart.
