The varied tooth size permits an overall coarser pitch for more aggressive cutting.
The one-piece arbor and hole saw combination eliminates the need for separate arbor attachments. Cuts mild steel, stainless and tool steel, cast iron, brass and aluminum.
All HSK Kits include one each of the following blade sizes:
Each kit also contains four (4) HSB 1/4" pilot bit replacments, one (1) HSX 13" arbor extension and one (1) stubby driver.
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.
