The 9 Best long Core Drill Bits (2023 reviews)

Here, we review bit that manages to win our hearts. It's the ediamondtools core bit and it's widely considered as one of all-around great bit you can buy. This is a wet core bit for concrete or brick. It's durable and chews cinderblocks with ease. It works, running it carefully with a heavy-duty 1/2" drill. The bit drills both holes cleanly with almost no sign of useage.

The speed of the grinder is perfect. The core bit itself is only 12" drilling depth so total length will only be 24" deep. It can be used in asphalt. The core drill has a water connection so keeps the bit wet. It would probably really hold up well for standard thickness concrete.
