Silver high-speed steel annular cutter with pilot pin and Weldon shank

Drill America

Drill America pneumatic accessory

SKU CH-R9M9-SCKM9

High-speed steel annular cutter cuts only the material needed for a clean hole, with a 3/4" Weldon shank for magnetic drill press use

  • High-speed steel construction resists wear for long life
  • Cuts only necessary material for fast, efficient hole making
  • 3/4" Weldon shank fits magnetic drill press only
  • Pilot pin included for accurate hole alignment
  • California Proposition 65 warnings apply for cancer and reproductive harm

9/16" HSS Annular Cutter

This high-speed steel annular cutter produces a 9/16 inch diameter hole with a 1 inch depth of cut. It features a 3/4 inch Weldon shank designed exclusively for magnetic drill presses. The cutter removes only the perimeter material for fast, efficient hole making in general-purpose applications.

Magnetic Drill Press Only

The 3/4 inch Weldon shank requires a compatible magnetic drill press and cannot be used with standard hand drills or conventional drill presses. A pilot pin is included to align the cut and eject the slug. This accessory frees the operator from removing the full core of material, reducing power demand and cutting time.

High-Speed Steel Construction

The high-speed steel body provides a balance of hardness and toughness for wear resistance during normal use. Cutting only the hole perimeter generates less heat and requires less force than solid twist drills of the same diameter. The tool contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm.

Questions about this item

How fast does the 9/16" HSS annular cutter dull when cutting mild steel all day?

The high-speed steel construction balances hardness and toughness for wear resistance, but cutting speed and feed rate determine actual edge life in sustained use.

Does the 3/4" Weldon shank cutter generate noticeable heat or vibration during continuous magnetic-drill operation?

Annular cutters remove only the hole perimeter, reducing friction and heat versus twist drills; the pilot pin aids coolant flow to manage temperature.

Will this cutter work with my existing magnetic drill press, or do I need a different arbor?

It requires a magnetic drill press with a 3/4" Weldon shank receiver; it will not fit a standard hand drill or conventional drill press.
