  • If I want a 4” Dia. Core, what size Core Bit do I need?

    You would need a 4-1/4” Core Bit.  Core Bits are sized based on their Outside Diameter. They are typically made from 1/8” thick wall tubing, thus, the ID is ¼” less. Hence a 4” Core Bit gives you a 3-3/4” Core. Typ. 6”, 8”, etc.

  • Do I have to use water when coring?

    Yes, if you want to maintain the life of the bit. If not, they will likely overheat and self-destruct.

  • What do you mean, General Purpose?

    You can use this bit on both concrete and asphalt.  You won’t get as many concrete cores as you would if using a Concrete Only Core Bit.  But, if someone just grabs it off the shelf and starts coring Asphalt or Concrete, it will perform and not ruin the bit.
