Our factory supplies HSSE straight shank twist drill bits, which include both black and white drill bit types, suitable for drilling operations on various materials such as iron, aluminum, plastic, and wood.
This series of drill bits is made of HSSE (high-speed steel with cobalt). Compared with ordinary high-speed steel, it has superior hardness, wear resistance, and high-temperature stability, enabling it to maintain stable cutting performance in processing different materials. The straight shank design is compatible with universal drill chucks, allowing for convenient and secure clamping, and can meet the usage requirements of various equipment such as electric drills and bench drills. The black and white drill bits are respectively optimized for different processing scenarios: the former focuses on enhancing surface lubricity to reduce friction, while the latter retains the original properties of the base material, making it suitable for working conditions with specific requirements for surface status.
Our factory controls the precision of the drill bit edges and the parameters of the flutes through precision machining to ensure smooth chip evacuation. The products have reliable performance and are widely applicable to mechanical processing, home appliance manufacturing, woodworking decoration, and DIY scenarios, providing customers with a versatile drilling tool solution for multiple materials.
