Beta Testing: Downcut End Mills for a Beautiful Burr Free Finish When Machining Wood or Plastic

摘要

2L inc., located in Hudson, Massachusetts, manufactures Solid Carbide Downcut Style End Mills. Downcut Style End Mills incorporate a helix opposite that of standard end mills or drills. The tools utilize a standard right-hand cutting edge but contain a left-handed spiral helix. This left-handed helix provides for a downward cutting action, which pushes burrs downward to improve the appearance of the workpiece top edge. This also prevents the lifting of workpieces being held in a vise or a vacuum chuck and is critical when machining thin sheet metal components, which can be bent or easily damaged.
