A custom tool can be created to machine a non-standard diameter, but it is more cost effective to use the closest standard sized tool. Tolerance - In any machining operation, the precision of a cut can be affected by several factors, including the sharpness of the tool, any vibration of the tool, or the build up of chips of material.

For non-standard sizes, the hole must be machined using an end mill tool, potentially increasing the cost. Also, limit the depth of all holes to 4 times their diameter . Deeper holes (up to 10 times the diameter) can be manufactured, but they will likely increase the cost, as they are problematic to machine.
