For use with a minimum 1/2-in (13 mm) cordless or corded electric drill and Malco combination Arbor and High Speed Pilot Drill. Malco Gutter Outlet Saws make safe, fast, clean cuts in thin walled and half round gutter. Downspout fits snug and flush with gutter every time. High speed steel teeth set at 10 per-inch (per 25.4 mm) will not grab or twist material, even when cutting half round gutter. The Pilot drill bit projects only 11 mm (7/16-in) out of the shallow 25.4 mm (1-in) gutter saw cup to ensure controlled safe engagement of the teeth. A tapered compression spring collar on the arbor pilot drill bit automatically ejects the metal slug. These saws may be used on the ground or on the roof, following power tool manufacturer’s instructions for drill operation.

Malco Products, Inc. got its start in 1950 when a young steel supply salesman, Mark W.Keymer, decided to manufacture and market a pipe crimper he had invented for use in installing the "new" sheet metal ductwork used with forced air heating systems. More tools soon followed, including: the first hand seamer to employ compound leverage; a time saving hand notcher that made a V-shaped cut in one motion; and a hand operated, snap lock punch to complete the basic sheet metal tool set. Today Malco Products, Inc. is the nation's leading manufacturer of "tools of the trade" for HVAC (Heating, Ventilating and Air Conditioning) professionals. In 1975 Malco also created a vital specialty tool market for EXTERIOR REMODELING professionals (Installers of Roofing, Siding and Gutter) and holds the leadership position in that niche as well. Corporate headquarters and manufacturing facilities are located in Annandale, Minnesota, just outside the Minneapolis / St. Paul metroplex. Malco continues its founder's tradition of leadership and innovation by addressing a changing industry landscape and responding to emerging market needs for new specializations and more customized products and services.
