Get the one tool that handles all your masonry projects with confidence Secure Setup & Pro-Efficiency Design: Get to work instantly with our all-in-one kit. The pilot drill is locked firmly by a robust hex set screw, ensuring zero wobble during the critical start-up phase. For the best results and deeper drilling, simply use the included Allen wrench to remove the pilot bit once the hole is established. This prevents resistance and ensures a smoother, more efficient cut through the entire thickness of the concrete Pro Tips for Peak Performance: To get the most out of your tools, here is a pro secret. When drilling through extremely hard materials like dense concrete or natural stone, using a steady stream of water will dramatically reduce friction and heat. This ensures a cleaner, smoother cut and significantly extends the life of the carbide teeth. For maximum safety and tool integrity, please avoid drilling directly into steel rebar.
