The Drill HSS 13.5mm 135° 1/Card Reduced Shank Industrial Bit is a high-performance drill bit designed for industrial applications. The 13.5mm diameter is suitable for drilling medium-sized holes in various materials, including metal, wood, and plastic. The 135° split point provides a sharp, precise cutting edge, helping to reduce the risk of wandering or slipping when starting a hole. The reduced shank design allows it to be used in drills that accept smaller chuck sizes (such as 1/2" or 3/8" chucks), while maintaining the larger cutting diameter of the bit. The HSS (High-Speed Steel) material ensures durability and strength, making it ideal for heavy-duty or high-speed drilling tasks. This drill bit is perfect for professionals and industrial users needing reliable performance and precision in demanding drilling tasks. It is sold individually in a card for easy storage and organization.
