Holders ending with QC have a quick-change mechanism, requiring no tools to change the hole saw
3834-ARBR-9100, -11152 and -16152 feature Power Driver, which increases strength and reduces backlash by redistributing load from the thread to the solid cap
Holders can be used with carbide hole saws, but we recommend using the carbide-tipped centre drill bit, 3834-DRL-CT, for cutting abrasive materials
Holders can be used for multi-construction hole saws, but drill bit 3834-DRL-L must be used for this purpose
HSS centring bit is included with all holders, for use in metal and wood applications
