Nouveau 4mm Extra Long 160mm HSS Twist Straigth Shank Auger Foret Outil

1. Twist drills are made from high-quality high-speed steel for increased durability. 2. The drill has a straight shank, which is more practical to use. Milled flutes with a deep cutting spiral allow for rapid material removal. The drill's flutes act as a passage for extracting chips from the hole and for allowing coolant to enter the hole. 3. This finish provides a highly adhesive surface treatment that helps retain the cutting fluid and prevents chip welding to the tool, thus reducing the formation of a built-up edge. 4. Drilling, or hole making, is the most common metalworking operation in the world. Twist drills are the most commonly used type of drill bit. Twist drills are commonly used to drill holes with hand drills, stand-alone drill presses, or drills. 5. This product is designed for impact applications, for rapid drilling in block, masonry, and concrete, etc.
