Lenox 4" Carbide Hole Saw is a high performance hole saw that is designed for drilling through wood, steel, stainless, cast iron, fiber cement and plaster. It has a patented speed slot staircase design that has multiple leverage points for easy plug ejection. It also drills through thick materials in one pass. The new Lenox carbide-tipped hole saws are designed for cutting tile and stainless steel up to 50x longer than previous generations of Lenox bi-metal hole saws. These high performance carbides are welded to the cutting edge for durability and to help prevent tooth loss. They are extremely versatile due to the aggressive tooth design which drills through wood, steel, stainless, cast iron, fiber cement, and plaster. The patented SPEED SLOT staircase design has multiple leverage points for easy plug ejection. Because of it's tall body, the hole saw easily drills through 2x dimensional lumber for rough-in work.
WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are: lead from lead-based paints, crystalline silica from bricks and cement and other masonry products, and arsenic and chromium from chemically-treated lumber. Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles. www.P65Warnings.ca.gov
