Abstract
A drill bit for use with construction using cross laminated timbers (CLT) is provided. The bit has both sharpened and dull portions of the cutting element of the bit, so that it can clean-out an opening in the CLT that has been partially obscured by shifts in the laminated constituents of the CLT, without elongating or otherwise changing the shape of the fastener opening. The use of the bit is made at the construction site in fastener openings previously made and otherwise obscured, thereby allowing the quick assembly and construction of a structure made of CLT.
