Installing caulking anchors, Pak-Tite and other drop in anchors can be a hassle. I have broken many depth stop rods and had to guesstimate the proper depth when in the field. Or I used tape to mark the proper depth on the bit, only to find each progressive hole becoming deeper as the tape pushed up the bit when it contacted the concrete. Bosch addressed this need with its new collection of Precision Masonry Stop Bits. Bosch uses a steel collar to mark the hole depth and once the collar touches the concrete the hole has reached its proper depth. No more proud or shy anchors.
Bosch offers a complete line of five carbide-tipped steel bits that include 3/8”, ½” and 5/8” sizes. Depths range from 13/16” to 2-1/16”. The size and depth range of the Bosch offering accommodates more than 80 percent of all requirements for drop-in anchors.
“The size and depth combinations prevent over-drilling and drilling into rebar,” said Andrew Pompei, product manager, masonry drilling, Bosch. “This is a better way for the professional user to install drop-in anchors properly and securely. These products speak not only to efficiency, but also safety.”
Bosch Stop Bits take the place of the manual depth gauge on rotary hammers, a feature many users disable. Drill bit maximum speed is 1100 rpm.
