Champion's Proline hammer core drill bits offer superior performance producing holes significantly larger than the rated power drive. Cutting the circumference of the holes leaves the center as a solid, so concrete removal is reduced for large size holes.
Used in rotary hammers operating in rotary hammer mode. Core bodies are machined from one single piece of steel. Cutting tips are put at irregular intervals to avoid setting up a sympathetic vibration when producing the hole. Each tooth presents itself to a random & new section of concrete as opposed to a piece previously hit by another tooth.
