Special Features
[Wide Material Compatibility] This drill bit set is designed for drilling a wide range of materials, including stainless steel, hardened steel, cast iron, copper, aluminum, plastic, and wood, making it ideal for both home craft projects and professional metalworking tasks. Please note that these drill bits are not suitable for glass, ceramics, or hardened bolts.
[Enhanced Durability] Each high-speed steel drill bit is designed for hard materials such as stainless steel and cast iron, providing reliable performance and extending tool life to meet the demands of harsh working environments.
[Precise Metric Sizes for Wide Application] The set includes 13 metric drill bits with diameters of 1.5, 2, 2.5, 3, 3.2, 3.5, 4, 4.5, 4.8, 5, 5.5, 6, and 6.5 mm. These sizes cover commonly used specifications in mechanical repair, electrical work, and model making. The straight shank design is compatible with standard electric drills and drill presses, while smaller diameter drill bits require careful control of speed and feed pressure to prevent overheating.
【High-Efficiency Chip Removal and Self-Centering Design】The auger's geometry features a double cutting edges, promoting faster penetration and efficient chip removal. This design helps the drill bit advance in the intended direction without lingering on the surface, thus reducing the need for centering. Polished flutes reduce friction and improve chip removal, making drilling operations on metals and plastics smoother.
【Convenient Storage and Organization】The drill bit comes with a plastic storage box for easy and quick identification and retrieval. The compact box protects the drill bit from damage and keeps it neat during transport or storage. When removing the drill bit for the first time, ensure the box fits snugly against the bit; it is recommended to gently pry the drill bit out with a tool to avoid bending or damaging the cutting edges.
