Will my keyed or keyless drill chuck work with BullseyeBore Core?
Please note that there are tens of thousands of power drills and drill chucks in use worldwide today, and the BullseyeBore team cannot possibly test all of them. Therefore, we have provided some general guidelines below. If you have a hex shank chuck, please see the Will my hex shank chuck with with BullseyeBore Core FAQ as well.
BullseyeBore Core is designed to work with a wide variety of common 0.375” (3/8”) or 0.5” (1/2") chucks that are used on common commercial electric drills. These two chuck sizes comprise most commercially available chucks in the US and EU. There are generally two criteria that you can use to assess before attempting to use the BullseyeBore Core product with your keyed or keyless drill chuck:
1: THE CHUCK MUST HAVE A METALLIC AND FLAT CHUCK FACE THAT IS 0.65” OR LARGER.
Your keyed or keyless drill chuck must have a flat metallic chuck face.The chuck face is the forward-most portion that the drill bit goes into. The flat chuck face is typically round in shape with a hole in the center for the drill bit. This hole contains the chuck jaws. BullseyeBore connects directly to the flat chuck face through a unique patent pending magnetic connection. For this to work properly, the chuck face must contain a large enough flat metallic surface to magnetically connect to BullseyeBore Core. Asa general guide, the outer diameter of the flat chuck face must be 0.65” or larger.
2: THE FLAT CHUCK FACE HOLE MUST BE EQUAL TO OR LESS THAN 0.56.”
The keyed or keyless chuck face hole must be equal to or less than 0.56” If the chuck face hole is larger than 0.56", then the extended chuck jaws can interfere with the connection between the face of the chuck and BullseyeBore Core. The use of keyed or keyless chucks with a chuck face hole larger that 0.56” is unsafe and must be avoided.
Please always test the fit and connection of the BullseyeBore Core product on your drill’s chuck face prior to any operations. Some chucks may require installation of an optional Chuck Alignment Guide. This is especially true with smaller keyed or keyless drill chucks such as 0.375” (3/8”) that are typical with smaller power drills. Always read and follow the BullseyeBore Core Safety Guidelines before attempting to use BullseyeBore Core or any BullseyeBore Core accessories on a drill or in an actual drilling operation.
