Drilling Data
Suggested Drill Size ~ Aluminum#31
Suggested Drill Size ~ Steel, Magnesium, Plastic#31
Minimum Drilling Depth for Bottoming Taps.212 in
Minimum Drilling Depth for Plug Taps.318 in
Drilling InformationThe minimum drilling depths shown below allow for the following recommended practices: 1. Countersinking the drilled hole to prevent a feather edge at the start of the tapped hole. 2. 3/4 - 1-1/2 pitch of insert ""set-down"" to allow for maximum production tolerance. Dimensions are shown for both plug and bottoming taps. (Note: Plug taps 5/16"" and smaller have a male center and the drilled hole depth dimensions allow for this length (one half of the diameter of the holt). Calculation of dimension ""F"" is as follows For Plug Taps 5/16"" and smaller: F = Insert Nominal Length (Q) + .5 (Bolt Nominal Diameter) + 4P (Tap Chamfer) + 1P (allowance for countersink and maximum insert set-down). For Plug Taps 3/8"" and larger: F = Insert Nominal Length(Q) + 4P (Tap Chamfer) + 1P (allowance for countersink and maximum insert set-down). For Bottoming Taps: F = Insert Nominal Length (Q) + 2P (Tap Chamfer) + 1P (allowance for countersink and maximum insert set-down).
