Does BullseyeBore Core require removal for a drill bit change?

BullseyeBore Core does not require removal for a drill bit change, but it is advised to do so whenever possible so that the drill bit can be fully engaged and secured into the chuck jaw teeth and verified prior to BullseyeBore Core attachment and drilling operations. However, when using a Spade, Auger, Forstner, or Step bit whose cutting diameter is larger than 0.5”, BullseyeBore should be securely attached to the chuck before attachment of the drill bit. In this case its best to:

1. Open the chuck jaws wide enough to support the drill bit shaft.
2. Securely attach BullseyeBore Core to the chuck and insert the bit.
3. Fully engage and secure the drill bit shaft into the chuck jaw teeth.
4. Verify that the chuck jaw teeth are fully engaged with the drill bit shaft prior to drilling operations.
5. Perform a low RPM test to make sure that the BullseyeBore Core is securely attached to the chuck face and the drill bit shaft is fully engaged as well as rotationally centered and secured in the drill chuck jaw teeth.
