Multi-Material Drill Bits

Micro-grain carbide tip provides maximum hardness and heat resistance reducing wear during extreme cutting applications. Self-centering, 118° point with 4 sharpened edges bores through multiple materials easily and accurately without walking or wandering. "S" ground flute design optimizes material removal. TIP: For best results, start by drilling through the softest material first and working yourself up to the hardest. Use percussion for concrete only. Appropriate use will extend drill life. One drill does it all: Alloy steel, composite, fiberglass, plastic, slate, brick, concrete, masonry, plexi-glass, wood, ceramic tile, drywall, plaster, and porcelain.
