2½" Countersink Drill Bit
Save Time, Labor & Money Setting Berntsen 2½" 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 C25DRLP countersink drill bit is used to install Berntsen 2½" concrete markers in asphalt or concrete. Use the C25DRLP to ream the proper counter sink depth, then use a 1" bit to expand the hole for the marker stem (Item # HC2146 sold separately) for a neat looking, long-lasting recessed monument.
- For SDS-Plus 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 # HC2146 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
