Silver annular cutter with pilot pin and Weldon shank

Drill America

Drill America DWC5-530-251 annular cutter pneumatic accessory

SKU CH-0K67-DRP4Z

A high-speed steel annular cutter with a 3/4-inch Weldon shank for magnetic drill presses, cutting only the material needed for a clean hole

  • High-speed steel cuts only required material for efficient holes
  • 3/4" Weldon shank fits magnetic drill presses securely
  • Pilot pin included for accurate hole centering
  • Hardness and toughness combine for reliable wear resistance
  • Designed for fast hole-making in general applications

Application scope

The Drill America DWC5-530-251 is a high-speed steel annular cutter with a 3/4 inch Weldon shank. It is built for magnetic drill presses only and will not work in a standard hand drill or conventional drill press. Buyers who need a cutter for portable hand-held drilling should choose a different tool.

Sustained cutting behaviour

The cutter removes only the material at the hole perimeter, reducing the volume of metal cut compared with a solid twist drill. High-speed steel construction provides a balance of hardness and toughness that resists wear during extended cutting cycles in general-purpose ferrous metals. Cutting efficiency remains consistent as long as the magnetic press maintains rigid alignment.

Thermals, noise and power

Heat generation is limited to the narrow cutting ring, allowing chips to carry away much of the thermal load. The accessory itself has no moving parts, so it adds no mechanical noise beyond the magnetic drill press motor. Power demand is determined entirely by the press and the workpiece material.

Questions about this item

How loud or hot does the DWC5-530-251 annular cutter get during continuous operation?

The cutter itself produces no motor noise or heat; all sound and thermal output come from the magnetic drill press driving it.

What equipment must I already own to use this 3/4″ Weldon-shank cutter?

A magnetic drill press with a 3/4″ Weldon arbor is required; it will not fit a standard hand drill or conventional drill press.

Will this HSS annular cutter work on the older Bridgeport mill I keep in the shop?

No — the 3/4″ Weldon shank is made for magnetic drill presses only and cannot be used in a Bridgeport or any standard milling machine.
