Installation Notes

This bit is installed and operated by any trade professional using a standard drill or impact driver with a 1/4 inch hex chuck. Ensure the drill is powered off and the chuck is clear before inserting or removing the bit. Use appropriate speed settings for the substrate material — lower speeds are recommended for metal to prevent overheating.
