Alfa Tools introduces tungsten carbide-tipped hole cutters for cutting many different types of materials, including construction steel plate, stainless steel, iron, aluminum, copper, cast iron, fiberglass and plastics. These industrial-quality cutters are used by contractors, electricians, plumbers, mechanics and HVAC professionals alike.
Alfa hole cutters produce burr-free holes so there is no additional finishing needed. The one-piece construction requires no assembly and provides stable, accurate cutting for a range of applications that include junction/switch boxes, metal studs, electrical appliances, lighting fixtures, auto body repair, vehicle frames, metal/ductile pipe, electrical and HVAC.
“Tungsten carbide-tipped hole cutters are an extremely productive tool that is a very good cost-effective alternative compared to bi-metal hole saws,” said Shaan Ahluwalia, vice president of sales and marketing, Alfa Tools. “You can drill considerably more holes with these cutters.”
The HSS pilot drill and ejector spring work together to eject plugs automatically after cutting. The safety stop collar prevents over-penetration. The hard tungsten carbide teeth resist heat and wear providing longer life.
The three-flatted shank design provides no-slip grip. It is ideal for cordless, keyless chuck and conventional power tools. The hole cutters can cut dry, but as always, Alfa recommends that you use a lubricant to ensure cleaner, precise cuts.
There are two depths of cut available, up to 3/16” or up to 1”. Choose diameters from 9/16” to 3”.

- chuck
chuck
Workholding device that affixes to a mill, lathe or drill-press spindle. It holds a tool or workpiece by one end, allowing it to be rotated. May also be fitted to the machine table to hold a workpiece. Two or more adjustable jaws actually hold the tool or part. May be actuated manually, pneumatically, hydraulically or electrically. See collet.
- high-speed steels ( HSS)
high-speed steels ( HSS)
Available in two major types: tungsten high-speed steels (designated by letter T having tungsten as the principal alloying element) and molybdenum high-speed steels (designated by letter M having molybdenum as the principal alloying element). The type T high-speed steels containing cobalt have higher wear resistance and greater red (hot) hardness, withstanding cutting temperature up to 1,100º F (590º C). The type T steels are used to fabricate metalcutting tools (milling cutters, drills, reamers and taps), woodworking tools, various types of punches and dies, ball and roller bearings. The type M steels are used for cutting tools and various types of dies.
- shank
shank
Main body of a tool; the portion of a drill or similar end-held tool that fits into a collet, chuck or similar mounting device.
- tungsten carbide ( WC)
tungsten carbide ( WC)
Intermetallic compound consisting of equal parts, by atomic weight, of tungsten and carbon. Sometimes tungsten carbide is used in reference to the cemented tungsten carbide material with cobalt added and/or with titanium carbide or tantalum carbide added. Thus, the tungsten carbide may be used to refer to pure tungsten carbide as well as co-bonded tungsten carbide, which may or may not contain added titanium carbide and/or tantalum carbide.
