Multifunctional drill bits with a hexagonal handle and YG6X alloy core for enhanced hardness. The blade is nitride treated for durability and wearresistance, providing burr edges and reducing edge breakage. Electrophoretic paint process delivers a ground, rustresistant exterior and a clean, keenedged finish. An automatic polishing step ensures consistency across each piece, producing neat, smooth holes without chipping or vibration. Unique cross angle design minimizes cutting resistance for stable, fast drilling. It helps prevent edge collapse and maintains precise, stable holes without compromising material integrity. Wide range of applications and compatibility. Suitable for professional and DIY use, these bits deliver smooth, precise holes in crockery tiles, marble, thin iron plates, mirrors, and glass. For results, use water or coolant while drilling to manage heat and prolong bit life. Use scenarios Installing fixtures and hardware in ceramic tiles or marble countertops, delivering clean, accurate holes without cracking surrounding material. Drilling through glass or mirror panels for frames, displays, or decorative installations with precise hole placement. Working on thin iron sheets or metal projects that require clean, precise holes with minimal burrs and edge damage.
