DeWalt HSS Annular Cutter DWAC02031 1-15/16 By 2 Inch Depth Core Drill Bit (3/4 In Weldon Shank Steel Plate Sheet Metal Magnetic Press Boring)

DeWalt DWAC02031 1-15/16" x 2" High-Speed Steel Annular Cutter

The DeWalt DWAC02031 1-15/16-inch by 2-inch high-speed steel annular cutter bores precision large-diameter holes through thick structural steel girders, heavy iron plates, truck frame channels, and commercial sheet metal. Engineered for industrial magnetic drill presses and dedicated core drilling equipment, this 2-inch depth-of-cut bit shears only the outer circumference of the hole to drastically decrease horsepower demand and eliminate the need for step pilot drilling. Manufactured from heat-resistant high-speed steel (HSS) with precision-ground multi-edge teeth and a standardized 3/4-inch Weldon shank with dual locking flats, it equips structural ironworkers, metal fabricators, and commercial mechanical contractors with fast penetration speeds, excellent chip evacuation, and smooth, burr-free hole edges.

Best Used For:

• Structural Steel Fabrication and Erection: Boring bolt-connection holes through structural I-beams, bridge girders, base plates, and heavy angle iron with magnetic drill presses.
• Heavy Machinery and Frame Modification: Drilling clean 1-15/16" holes in commercial truck chassis rails, excavator boom brackets, and agricultural implement hitches.
• Industrial Piping and Flange Connection: Core-drilling penetrations into thick-wall steel pipes, pressure vessel flanges, and structural unistrut channels without plate distortion.

Key Performance & Safety Features

• Industrial High-Speed Steel Alloy: Tough HSS metallurgy maintains tooth hardness under high frictional cutting temperatures during long boring cycles.
• Multi-Edge Alternating Tooth Geometry: Precision-ground cutting tips divide chip load evenly across teeth to reduce machine chatter, harmonic vibration, and tooth chipping.
• Deep 2-Inch Core Boring Capacity: Extended cutter body length effortlessly cores through multi-layer steel plates and thick solid structural iron sections up to 2.0 inches deep.
• Optimized High-Flow Chip Flutes: Wide spiral flute geometry rapidly pulls hot metal shavings upward away from the hole bottom to minimize thermal buildup and cutter binding.
• Standard 3/4-Inch Weldon Shank: Precision-machined shank with dual flat locking sectors fits securely into magnetic drill press arbors to prevent rotational slippage under heavy torque.
• Clean Slug Ejection Compatibility: Hollow center cavity pairs with standard pilot pins to channel pressurized internal coolant and automatically eject the center metal slug upon breakthrough.

Technical Specifications

Pro-Tip: Always use an internal pilot pin with pressurized water-soluble cutting fluid when drilling on a magnetic base; continuous coolant delivery directly to the inner cutting teeth extends high-speed steel edge life and ensures the center steel slug pops out instantly at breakthrough.
