摘要： A boring tool for producing undercuts in preformed holes. The boring tool has a cutting element which is provided at one end of a driving shaft. In order to produce the undercut, the driving shaft can be deflected at right angles to the axis thereof via a deflection mechanism. The deflection mechanism is accommodated in the boring tool, and is provided with a longitudinally displaceable deflection rod for positively deflecting the driving shaft. In the deflected position, the driving shaft is driven by a rotary drive which is separate from the turning drive. As a result, the undercuts can be very precisely produced.

摘要： 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.
