IRWIN 326002B25 3/16" 2" 3 1/2" Masonry Drill Bit, 25-Pack

Get reliable, jobsite-ready performance for security and surveillance installations with the IRWIN Tools masonry drill bit 25-pack. Designed for professional installers, these 3/16" diameter masonry bits deliver fast, consistent holes for anchors, camera mounts and conduit runs. The double-ground tip and extra-deep flutes eject dust quickly to maintain cutting speed and reduce binding, while the Chrome Vanadium Spring Steel construction stands up to repeated percussion and heavy-duty use.

Each bit offers a 2" working length and a 3 1/2" overall length — ideal for common anchor depths and passthrough applications. Supplied as a 25-pack, this set keeps technicians stocked for multi-camera surveillance installs, monitoring equipment mounts and network cabling anchors. Compatible with hammer drills using a 3-jaw or Jacobs chuck, these rotary percussion bits make setup and teardown more efficient across construction, security and low-voltage projects.

Choose IRWIN Tools masonry bits to speed installations, extend tool life and maintain professional results on every job. Keep a pack in your toolbox or order enough for your next camera, access control or networking deployment.
