The 5 Best coring Drill Bits (2023 reviews)

It is designed to drill soft brick and building block. The drill bit is very long so you need a steady hand. The cutters of the barrel are buried into the material to remove the pilot drill bit for better cutter engagement. The bit is a fairly small diameter which allows some flex in the bit for horizontal drilling. It will walk and bend the pioleit bit.

The 4" hole is a snug fit for 4"ductwork so wiggle it to slightly overcut the hole. It can be used wet or dry.
