What is 7 16 Tap Drill Size
The 7 16 tap drill size is 11/32 inches (8.73mm). The 7 16 tap drill size is the recommended size to use for drilling a hole into which a 7/16 inch thread cutting tap will be used. The drill bit size should create a hole that is slightly smaller than the tap, so that when the tap is inserted and twisted, it creates threads in the material. Using the correct drill bit size will ensure that the tap engages correctly with the material and does not become damaged during installation.
What Size Drill Bit Do I Use for a 7 16 Tap?
For a 7/16-inch tap, you should use an 11/32 drill bit. This drill bit size will create a hole slightly smaller than the tap and allow it to thread into the material without becoming damaged.
What Can I Use if I Don’t Have the Right Size Drill Bit?
If you don’t have the correct drill bit size, you can use a smaller drill bit and then enlarge the hole with a tap reamer. Tap reamers are available in different sizes to match the diameter [1] of the tap and will help ensure that the threads created by the tap are correct.
