This 10-piece set of 3/16 in. hexagonal drill bits is your reliable assistant for drilling operations. Each drill bit has precise dimensions, providing you with professional grade drilling specifications. The accompanying portable plastic box makes storage and carrying easy and convenient. The drill bit is coated with high-quality HSS titanium and made of industrial grade 4341 high-speed steel material, with a hardness far exceeding that of ordinary 4241 HSS drill bits. The titanium coating further enhances wear resistance and durability, ensuring long-term efficient use. The unique advantage of this drill bit is its full grinding process combined with a 135 ° dividing point design. The fully ground spiral groove quickly discharges particles, reduces friction and heat, and achieves fast and low-temperature drilling. The straight handle design with a 135 ° dividing point effectively prevents the drill bit from moving during drilling, resulting in higher drilling accuracy without the need for center punch assistance. Small drill bits have a wide range of applications and can be used to drill holes in soft metals, wood, plastics, as well as steel, aluminum alloys, and other materials with a thickness of less than 5 millimeters. They are an ideal choice for DIY projects, home maintenance, and repair. However, please note that it is not applicable for drilling holes in glass, ceramics, or concrete.
