3½" Countersink Drill Bit
A new way to set recessed Berntsen 3½" diameter concrete markers

"The countersink drill bit we purchased to install Berntsen concrete markers works PERFECTLY! We scheduled 2 days labor and ended up only using about 5 hours. It's very handy, still in great shape and paid for itself the first time we used it." - Jake Teegarden, Vasconcelles Engineering Corp., Springfield, IL

The C35DRLS countersink drill bit is specially designed to install Berntsen 3½" - "C" style concrete markers in asphalt or concrete. Use the C35DRLS to ream the proper countersink depth, then

use a 1" bit to expand the hole for the marker stem (item # AE-505-145 sold separately) for a neat looking, long-lasting recessed monument.

  • For Spline chuck rotary hammer drills only
  • This drill bit countersinks the top of the marker only (not the stem). We suggest a 7/8" or 1" drill bit to create the stem hole (item # AE-505-145 sold separately)
  • Three-piece design - No longer necessary to replace entire bit when one section wears out
  • Berntsen recommends at least a 24-volt Rotary Hammer drill be used with these drill bits
