The Morse, MHS09 (177092), 9/16" (14mm) diameter, bimetal hole saw is a durable, versatile tool designed for general purpose use. Whether cutting materials from stainless steel to plastic, plate or tubing, the patented tooth set and positive rake tooth profile ensures cuts are faster and smoother, saving time and effort. A unique feature of Morse hole saws is the side slot design that eases slug removal. The key is in the multiple leverage points available, regardless of material thickness. The 1-15/16” cutting depth provides a wide range of uses. Whether working on a DIY project or a professional job, rely on Morse performance. Separate arbor is required for use. Morse recommends the MA24 (139007) or MA34 (139014) arbor, depending on drilling equipment options. To optimize performance, consider using with Morse CUTLUBE (121408). Each box contains one (1) hole saw.
