Special Features
SIZE:Covering three practical sizes (1/8", 3/16", 1/4"), this set is perfect for popular applications like installing #8 to #12 screws or drilling holes in light-gauge metal. The carbide tips are optimized for precision drilling, guaranteeing accurate results every time and making your work more efficient
STABLE CLAMPING DESIGN:The stable round shank of these drill bits ensures operational steadiness, preventing shake and slip. Advanced sharp flutes enable rapid, smooth, burr-free cuts, reducing cutting force and breakage for superior hole quality and exceptional performance
SHARP SPIRAL FLUTES:The sharp spiral flutes of these drill bits for metal ensure pristine, smooth cuts, boasting robust cutting edges and swift speeds. Their spiral groove design facilitates effortless chip removal, reducing heat and pollution for an optimal drilling encounter
PREMIUM MATERIAL: Made from 0.6μm micro-particle cemented carbide, these drill bits for hardened steel offer excellent wear resistance and strength, excelling in high-speed, high-hardness cutting for improved efficiency and durability. However, due to the brittleness of tungsten steel, it's recommended to operate them at speeds exceeding 3K rpm and handle with extra care to prevent damage
VERSATILE USE:This drill bit set excels in diverse metal drilling tasks including stainless steel aluminum cast iron mold steel and copper. Trusted across workshops and industries these drill bits sets deliver reliable and durable performance for every application
USAGE TIPS: To maximize performance and minimize breakage, always use these bits in a stable drilling setup such as CNC machine tools. Do not use with hand-held power drills. Apply steady, moderate feed pressure and avoid bending or side-loading forces during operation for clean results and long tool life
