2in Asphalt Core Drill Bit (Open-Head) is used with electric or gasoline-powered Core Drills to obtain drilled asphalt cores for evaluation and laboratory testing. The bit requires a properly sized Expander Set for Open-Head Asphalt Coring Bits for attachment to the drilling machine. It performs well in high-output, heavy-use applications, and can be refurbished when worn.

Product Q&A

Q: How are longer specimens extracted and the piston returned?

Specimens longer than 5in are extracted by repositioning the Adapter Ring after maximum piston travel, and the spring-loaded piston automatically returns to the start position when the release valve is opened.
