2" Countersink Drill Bit
Save Time, Labor & Money Setting Berntsen 2" Concrete Markers
The CD2DRLM countersink drill bit is used to install Berntsen 2" concrete markers in asphalt or concrete. Use the CD2DRLM to ream the proper counter sink depth, then use a 1" bit to expand the hole of the marker stem (item # SM-420-420 sold separately) for a neat looking, long-lasting recessed monument.
- For SDS-Max 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 # SM-420-420 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
"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
