Dewalt DWA1784IR Impact Ready Step Drill Bit - 3/16in-1/2in

The DeWalt DWA1784IR is a 3/16 in. to 1/2 in. Impact Ready Step Drill Bit engineered for use with impact drivers and standard drills. Designed for drilling clean, accurate, and progressively sized holes in sheet metal, thin steel, aluminum, and other light-gauge materials, this step bit is a go-to tool for electricians, HVAC technicians, and metalworkers.

Key Features:

• Impact Ready design — features a 1/4 in. hex shank with torsion zone to absorb peak torque and extend bit life when used with impact drivers
• Step range: 3/16 in. to 1/2 in. — drills multiple hole sizes with a single bit, reducing the need to swap tools
• High-speed steel (HSS) construction — delivers long-lasting durability and heat resistance
• Titanium coating — reduces friction and extends bit life compared to uncoated bits
• Laser-etched step markings — clearly visible size indicators stay readable throughout the life of the bit
• Split-point tip — starts on contact for precise hole placement without walking or center-punching
• 1/4 in. quick-change hex shank — compatible with all standard impact drivers and drill chucks

The DWA1784IR is part of DeWalt's Impact Ready accessory line, built to withstand the high-torque demands of modern impact drivers. Whether drilling conduit knockouts, junction box holes, or pilot holes in light metal, this step bit delivers consistent, burr-free results hole after hole.
