    Drill clean 2-1/2" holes through exterior walls. No water. No hammer mode. No guesswork.
    The CrownForce CF-WC-65 dry core bit is built for one job: punching mini-split line-set holes and pipe pass-throughs straight through concrete, brick, and block walls. With 10 inches of working depth, it clears a standard exterior wall in one shot.

    Fits the drill you already own▼
    • SDS-Plus adapter. Fits your rotary hammer (rotation-only mode).
    • SDS-Max adapter. Fits larger demo-class drills.
    • 1/2" hex adapter. Fits standard drills and hole saw arbors.
    Built to last on real jobs▼
