![]() ![]() This creates a torque at the narrowest unsupported part of the bit. Runout can cause bits to break! If a bit begins to enter the substrate at an angle, it will have a tendency to continue down that angular path. ![]() The bit is at an angle to the axis of rotationĪ) Ideal: axis of drill bit is co-linear with axis of rotation, b) Axis of drill bit is offset from axis of rotation, c) Axis of drill bit is at angle from axis of rotation.The bit is off center from the axis of rotation.Reality is far less kind so holes will actually be larger for two main reasons: If we lived in an ideal world, a drill would create holes the exact diameter of the bit you use. In this case, there were many things to consider: power, speed, torque, size, weight, baud rate, etc., but the number that we absolutely had to hit was runout. Designing this user experience was a battle between our ambition and physical limitations. In the few months since we released the Voltera V-One Drill we’ve had many users tell us that it has greatly improved the double-sided circuit workflow. ![]()
