FIRST CORE?

THREE CHECKS BEFORE YOU ORDER.

SIZE THE HOLE, NOT THE PIPE.

Your bit diameter is the finished hole you need, including sleeve and clearance. Size to what passes through, not to the pipe label.

CHECK YOUR MOUNT.

These bits run a 1-1/4 inch, 7 thread connection, the common core rig standard. Confirm your rig or adapter before you order.

CORE WET.

Water cools the segments and clears slurry. Plan your water feed and cleanup before the first hole.
