Specifications

Pro-Tip: When coring with a 4-1/2" bit, the surface area of the segments is significant. To prevent the bit from "polishing" or becoming dull, maintain a steady downward pressure that produces a consistent, milky slurry. If the water runs clear, the segments are likely gliding rather than cutting; briefly reducing water flow can help the segments "open up" and regain their aggressive cutting edge.
