To connect the drill to the Flange Adaptor, a threaded adaptor is required. 

Pipetech has a variety of sizes available within the drilling range, with the option of extended versions to increase reach. 

Flange Adaptors are necessary to link the fitting you are attaching to the drill, like a valve, for example.

Traverse Extenders increase how for the drill will travel

Holesaw Holders are used to attach the holesaw to the drill spindle and keep them in place

Carbide Tipped holesaws are provided, enabling the drilling of a wide variety of materials

The pilot drill gives a concentric hole for holesaws and is complete with coupon retention, which catches the coupon once drilled, preventing it from falling into the pipe.
