DeWalt Annular Cutter DWAC02023 3/4 Inch Weldon Shank Magnetic Drill Bit (1-7/16 Diameter 2 Cut Depth Ground Flutes Steel Plate Hole Boring)

DeWalt DWAC02023 1-7/16" x 2" HSS Annular Cutter (3/4" Weldon Shank)

The DeWalt DWAC02023 1-7/16-inch x 2-inch high-speed steel annular cutter bores burr-free through-holes across heavy structural steel beams, thick industrial plates, truck frame rails, and sheet metal fabrications. Engineered from premium M2 high-speed steel with precision-ground multi-tooth cutting geometry, this core drill accessory removes only the periphery of the hole to increase drilling speed and minimize machine motor strain compared to standard solid twist bits. Outfitted with an extended 2-inch maximum drilling depth capacity, enhanced spiral flutes that lift metal chips cleanly out of deep bores, and an industry-standard 3/4-inch Weldon shank with dual retention flats, it equips steel fabricators, commercial ironworkers, and mechanical field contractors with chatter-free hole broaching across portable magnetic drill presses and stationary machine tool arbors.

Best Used For:

• Structural Steel Framing and Girders: Coring clean 1-7/16-inch bolt connection holes in heavy wide-flange I-beams, structural columns, and baseplates on jobsite erection projects.
• Heavy Plate and Tube Fabrication: Boring through thick alloy steel plate, box tubing, and channel sections up to 2 inches thick without pilot pre-drilling.
• Commercial Vehicle and Machinery Repair: Drilling precision mounting points in truck frame chassis rails, agricultural implements, and heavy equipment assemblies.

Key Performance & Safety Features

• High-Speed Steel Construction: Premium-grade high-speed tool steel core maintains cutting edge hardness under severe frictional heat and thermal expansion.
• Precision-Ground Tooth Geometry: Multi-cut tooth profile distributes chip load evenly across cutting edges, dampening chatter and producing clean, smooth hole rims.
• Deep 2" Boring Reach: Extended hollow core barrel penetrates steel plates and hollow structural sections (HSS) ranging from 1/8 inch up to 2 inches in thickness.
• Enhanced Spiral Flute Design: Optimized external fluting evacuates dense metal swarf and chips continuously from deep holes to eliminate bit binding.
• Standard 3/4" Weldon Drive Shank: Features dual precision-milled locking flats that secure tightly into standard magnetic drill chucks for slip-free power transmission.
• Core Plug Ejection Compatibility: Hollow cylinder body accepts standard spring-loaded pilot pins to center holes accurately and automatically eject the center steel slug.

Technical Specifications

Pro-Tip: Always use internal cutting lubricant or cutting fluid with a center pilot pin; continuous cooling fluid keeps tooth edges below annealing temperatures and ensures the compressed pilot spring automatically ejects the steel slug the second the cutter breaks through the bottom face.
