【NITRIDED HSS】- Made of high quality 4241 high speed steel and coated with nitride, which can improve the drill bits' durability and cutting efficiency.
【TWISTED DESIGN】- With a 125° angle point and twist design, it can increase the cutting speed through automatic centering; avoid displacement during the work process, and at the same time remove debris and particles faster and easier. The straight shank can be firmly fixed and accurately centered, suitable for standard drill chucks and conventional round chucks.
【PROFESSIONAL AND DIY USE】- Designed for drilling holes in plastic, wood and soft metal like aluminum, iron, etc. It has a cylindrical shank system (shank equal to drill bit diameter) and is intended for use in drill stands and drill drivers. When it cannot penetrate, try to adjust the RPM.
【NOTE】- Please keep cool and gentle using, the working life of the twist drill bits can be largely prolonged by proper usage.
