Asphalt Diamond Coring Drill Bits are available as Open-Head or Closed-Head Bits. Open-Head is the cheaper style and is used for heavy routine applications and must-use expander sets. Closed-Head is more convenient and easier to attach, and best suited for light to medium work applications. Both styles are optimal for asphalt pavements. Looking for bits for concrete? See Concrete Coring Bits.
Note: Open-Head Coring Bits require Expander Sets
All coring bits are built for wet environments and are fast-cutting when used for specific applications. The standard length is 14in (356mm) for coring up to 13in long. Our most popular bit sizes are listed here. Please contact us for sizes not shown.
