• Arbors ending with QC have a quick-change mechanism where no tools are needed to change the holesaw • 3834-ARBR-9100, -11152 and -16152, are equipped with Power Driver™ that increases the strength and eliminates play of the holesaw by redistributing the load from the thread to the solid cap • Arbors can be used with carbide holesaws but we recommend to use the carbide tipped pilot drill, 3834-DRL-CT, for cutting abrasive materials • Arbors can be used for multi-construction holesaws but it requires changing the drill to 3834-DRL-L • HSS Pilot drill is included in all arbors, to be used for metal and wood applications • Easy change of holesaw with quick change mechanism
