How to use

Select the bit diameter required for the anchor, plug or fixture to be installed. Secure the chosen bit in the drill chuck according to the drill manufacturer’s instructions, ensuring it is tightened and centered. When drilling concrete or masonry, use steady pressure and, if available, the hammer function on a compatible drill for improved penetration. Begin at low speed to establish the hole, then increase RPM as appropriate. Periodically withdraw the bit to clear dust and prevent overheating. Wear appropriate personal protective equipment including eye protection, hearing protection and a dust mask.

Usage recommendations

Use the spiral/blade bits from the MODECO MN-61-109 set with a drill that supports hammer action for faster results in concrete. Match drill speed and pressure to the diameter and material; clear dust frequently and replace bits that show excessive wear to maintain drilling efficiency and hole accuracy.
