13Pcs/Set 7/16 to 1-1/16'' Cutting Diameter Annular Cutters Set 1'' Cutting Depth

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. 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. Complete Specifications: This is a complete set of annular cutters that includes a variety of drill sizes(7/16, 1/2, 9/16, 11/16, 5/8, 3/4, 13/16, 7/8, 15/16, 1, 1-1/16) for your convenience. And the different sizes of cutter heads provide you with more precise drilling. Waste Reduction: These annular cutters re-sharpen and smooth burr-free and smooth holes, thus reducing scrap and material waste for you. High Portability: With a weight of 1.2kg/ 2.65lbs, this annular cutter set is light enough to be carried anywhere you want, facilitating your daily use. 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.
