The Drill Bit HSS Standard 13.5mm with a Reduced Shank is a high-speed steel (HSS) drill bit designed for general-purpose drilling in materials like metal, wood, and plastic. The 13.5mm diameter makes it suitable for creating medium-sized holes. The reduced shank allows it to be used in drills with smaller chucks (typically 1/2" or smaller), providing flexibility while maintaining the strength and durability of the larger diameter bit. The high-speed steel construction ensures the drill bit can withstand high temperatures, offering longevity and precision. This drill bit comes in a single card for easy storage and use in professional and DIY applications.
