4 Flute Eccentric Drill Bit Carbide Tip Serrated Jag Masonry Oxide Dry Ceramic Tile Glass Marble Concrete Wall Stainless Steel

The 4 Flute Jagged Eccentric Dry Drill Bit is a professional-grade drilling solution designed for the toughest materials. Unlike standard drill bits, this eccentric design with 4 cutting edges delivers exceptional performance on full porcelain tile, ceramic, glass, marble, concrete, and stainless steel – all without water cooling.Why This Bit is DifferentEccentric Design – The off-center rotation creates a "wobbling" motion that prevents the bit from grabbing and cracking hard, brittle materials like glass and ceramic tile. This reduces breakout and delivers cleaner holes.4 Flute / 4 Tooth Jagged Edge – Four aggressive cutting edges work together to remove material faster, reduce heat buildup, and provide smoother drilling action compared to standard 2-flute bits.Dry Drilling Capability – The optimized flute geometry and yellow heat-resistant coating allow for dry drilling on materials that typically require water cooling. No messy water setups or special equipment needed.Heat-Resistant Yellow Coating – The high-temperature yellow coating (similar to TiAlN or ZrN) reduces friction, dissipates heat, and protects the bit from wear during high-speed dry drilling on hard materials.4 Flute Jagged Edge Design – Four aggressive cutting teeth provide faster material removal and smoother drilling on hard materials like porcelain tile, ceramic, glass, marble, and stainless steel.Eccentric Wobble Technology – The off-center rotation prevents grabbing and cracking on brittle materials. Drills clean holes in glass and ceramic tile without chips or breakage.Dry Drilling Without Water – Advanced flute geometry and heat-resistant yellow coating allow dry drilling on materials that typically require water cooling. No messy water setups needed.Yellow Heat-Resistant Coating – High-temperature coating reduces friction, dissipates heat, and extends bit life during dry drilling on concrete, stainless steel, and stone.One Bit for Multiple Materials – Works on full porcelain tile, ceramic tile, glass, marble, concrete, stainless steel, granite, and brick. Replace multiple specialty bits with one tool.
