High Strength Extended Spiral Impact Hammer Drill Bits Gina Carano Wikipedia. FEATURES PENETRATE TOUGHEST MATERIALS WITH EASE Engineered from high strength alloy, these bits drill effortlessly through concrete, brick, and stone without bending or breaking. The spiral flute design efficiently removes debris, maintaining optimal drilling speed and reducing bit wear. EXTENDED LENGTH REACHES DEEP SURFACES Available in lengths up to 200mm, these bits access recessed areas and thick materials that standard bits cant handle. Perfect for plumbing, electrical, and construction tasks requiring deep penetration. DOUBLE SHANK OPTIONS FOR UNIVERSAL COMPATIBILITY Choose between square or round shanks to fit all major hammer drills and rotary hammers. The secure grip minimizes slippage, delivering maximum power transfer for faster, cleaner holes. HEAT RESISTANT DESIGN FOR LONGER LIFESPAN The hardened alloy construction withstands high temperatures generated during prolonged use, preventing premature dulling. Outperforms standard bits by 3x in durability tests under heavy duty conditions. PRECISE SIZING FOR ACCURATE HOLES Available in 6mm18mm diameters with clearly marked sizing, ensuring perfect fit for anchors, pipes, and conduits. The sharp tip reduces walking for clean starts on uneven surfaces. SPEC Material: High Strength Alloy Shank Type: Square Shank, Round Shank NOTES Always use eye protection and secure workpiece before drilling. Match bit size to hammer drill chuck capacity. Reduce speed when drilling reinforced concrete. Store in dry place to prevent rust formation. Replace bit when cutting edges show significant wear.
