13Pcs 7/16 to 1-1/16'' Cutting Diameter Annular Cutter Tool Straight Shank 1 Set

Drilling Partner: These annular bits drill large holes much faster than regular bits, and their magnetic bits are thin-walled with double alternating teeth, making it easier to make efficient and aggressive cuts than traditional hole saws and twist bits, saving you time and effort on the job. Ring Cutting: Its inserts are geometrically designed, making it easy to punch holes even at awkward angles. And because annular cutters have fewer teeth and less wear, drilling can be done at faster cutting speeds with ring cutters. Good Material: This annular cutter set is made of high-quality high-speed steel M2 material, with strong hardness and good corrosion resistance, so it can be used for a long time.
