2" Countersink Drill Bit

...a new way to set perfectly recessed two-inch diameter concrete markers fast!

 "The greatest thing since sliced bread!  This countersink drill bit has really made life easier for me."

Jim Frame, Frame Surveying - Davis, California

Now you can drill the shaft hole and countersink in one pass!  The CD2DRL countersink drill bit is specially designed to install Berntsen's CD2 series markers in asphalt or concrete.  Just drill the 7/8" hole needed for the monument shaft and keep going to ream the proper countersink for a neat looking, long lasting, recessed monument placement.  The countersink will be perfectly aligned, the shaft hole will be the proper depth and you won't have to change drill bits!  The CD2DRL fits a SDS-Plus chuck and works with the Bosch 36V Hammer Drill.  A spline to SDS adapter is available that allows use with spline hammers (click here for SDS adapter).
