New Drill and Bit Combination Slashes Installation Time

Berntsen International, Inc. announces the addition of TWO NEW products, the Bosch 36-volt Lithium Battery Rotary Drill and a Berntsen original, the 2” Countersink Drill Bit. The two products, used in tandem, cut the installation time of any 2-inch concrete marker in half.

In the past, surveyors would need to complete a rather cumbersome process to set the 2-inch concrete marker. Typically, one would drill the center hole and then trace the 2-inch circumference of the marker onto the concrete with a pencil. Next, they would hand-chisel away the concrete in the area where the top of the marker would need to be recessed. Once the chiseling process was complete, the marker could be glued or cemented in place.

The new 2-inch Countersink Drill Bit, created specifically to simplify this process, drills the countersunk hole, including the hole for the stem, in one easy, quick step - cutting marker setting time from roughly 30 minutes down to ten.

Testing of the new bit shows that it performs best when used with an electric-powered drill or the new 36-volt drill by Bosch. “In the past, it was tough to market this kind of bit because the lower voltage drills couldn’t handle the bit, but the new 36-volt drill handles the job fabulously,” says Claudia Fuller, Customer Service Manager of Berntsen. “We knew the bit was needed in the field, but until recently the battery-powered drills didn’t have the power to handle it.”

Whether you use your electric drill, the 36-volt drill, or any drill with an impact force of 2.2ft.-lbs., you'll find setting the 2" markers pleasantly simple. As Rhonda Rushing, president of Berntsen says, “We’re continuing our mission to help surveyors make their mark on the world - and providing new, fast, and easy ways to get the job done is one way to help the surveyor do just that!”
