SKU CH-28PC-VHSNN

nACo coated annular cutter cuts steel, cast iron and stainless steel efficiently with a 3/4" Weldon shank for magnetic drill presses

  • nACo Nano-Composite coating extends tool life up to 30% over traditional HSS cutters
  • Cuts steel, cast iron, heated and stainless steels for versatile material handling
  • nACo coating provides extra protection against tool wear and high heat
  • M2 High Speed Steel removes only necessary material for fast, efficient hole making
  • 3/4" Weldon shank fits most magnetic drill presses for broad compatibility

Drill America nACo 9/16" Annular Cutter

This coated cutter is built for magnetic drill presses, removing only the perimeter of a hole in steel, cast iron, heated or stainless grades. The nACo nano-composite finish extends usable life by roughly 30 percent over standard high-speed steel cutters, reducing change-over time on repetitive work. A 3/4" Weldon shank secures it in most mag-drill chucks, and the included pilot pin keeps the cut centred from the first revolution.

Magnetic-drill operators cutting structural steel

Shops that rely on hand-held drills, bench presses or CNC spindles cannot use this tool because the shank and cutting geometry are exclusive to magnetic bases. Teams needing through-holes larger than 9/16 inch or deeper than the cutter’s length will have to select a different diameter or a longer series. The California Proposition 65 notice also means facilities with strict chemical-exposure policies must review the warning before purchase.

9/16 inch cutting diameter

This single dimension determines whether the cutter matches the hole size specified on the drawing or the fastener being installed; no other specification in the data overrides that requirement.
