AS A GENERAL GUIDE FOR DRILL COMPATIBILITY, BULLSEYEBORE CORE WILL WORK WITH MOST COMMON COMMERCIAL ELECTRIC DRILLS THAT MEET THE FOLLOWING CONDITIONS:
The drill chuck face is metallic and flat. The “chuck face” is the very front of the chuck.
The drill chuck is a common keyed, keyless, or a standard ¼” hex shank chuck.
The drill chuck has a bit hole of less than or equal to 0.56" diameter.
The maximum drill RPM is equal to or less than 2500 RPM.
BullseyeBore Core and the accessories were designed with the goal of working with most common standard electric drills and drill chucks, but due to the vast number of drill and chuck combinations, some careful user testing is required prior to use. Please read and follow the BullseyeBore Core Safety Guidelines before attempting to use BullseyeBore Core or any accessories on a drill or in an actual drilling operation.
You MUST use a Standard Chuck Alignment Guide if you intend to mount BullseyeBore Core on a hex shank chuck or a chuck with a small front face. Most standard chucks also benefit from a Standard Chuck Alignment Guide for proper operation and alignment. A Standard Chuck Alignment Guide prevents displacement of BullseyeBore Core across the chuck face or detachment during rotation.
Chuck Extensions are recommended for use with bits 4"+ in length including spade and auger bits. Chuck extensions are also recommended for use with the CR1-100 and CG1-100 models.
The BullseyeBore Core versions have certain visibility limitations depending on lighting conditions. None of the current versions will be operationally visible in direct sunlight. In indirect sunlight, the Core Green versions (CG1-100 and CG1-101) are visible in some conditions, though visibility may be limited depending on ambient light intensity. However, Core Green versions perform well in bright indoor lighting environments.
