The 1/8" Solid Carbide Down-Cut CNC Router Bit is a must-have for any craftsman or CNC operator looking for precision and quality in their work. With a tip diameter of 1/8", shank diameter of 1/4", a length of cut of 1", and an overall length of 2-1/2", this bit is specially designed for clean cutting on the top surface of the workpiece. The down-cut flutes push the chips downward, which is particularly advantageous in reducing fraying and chipping, ensuring immaculate edges. Moreover, this bit is not only exemplary for woodworking but is also highly effective for cutting plastics and aluminum, enhancing its versatility. One of the standout features of this router bit is the Astra coating, which substantially elevates its performance by facilitating higher cutting speeds, feed rates, and providing extended tool life, especially in abrasive materials. It's worth noting that the down-cut design pushes waste back into the cut area, so it's advisable not to use this bit for cutting dados or drilling holes. The bit should also be run at slower speeds in terms of both revolution and spindle movement. Being manufactured in the USA, this down-cut CNC router bit embodies top-notch quality and precision, making it an indispensable tool for professionals and enthusiasts seeking excellence in their projects.
