7/8" Reduced Shank Black Oxide Drill Bit DW1627-SBD

Dewalt's 7/8" Reduced Shank Black Oxide Drill Bit (DW1627-SBD) is a heavy-duty accessory designed for boring large-diameter holes in a variety of materials including metal, wood, and plastic. Constructed from high-speed steel with a black oxide finish, this bit is engineered for increased wear resistance and enhanced lubricity to reduce heat buildup. The 1/2-inch reduced shank allows the large 7/8-inch bit to be used in standard 1/2-inch drill chucks, making it a versatile choice for construction and metalworking applications where oversized holes are required.
Key Features
Black oxide finish resists corrosion and reduces friction for cooler, smoother drilling performance.
1/2-inch reduced shank enables the use of a large 7/8-inch bit in standard 1/2-inch drill chucks.
135-degree split point tip starts on contact to minimize bit walking and ensure hole precision.
High-speed steel construction provides the durability needed for drilling through non-ferrous metals.
Parabolic flute design improves chip ejection to prevent clogging during deep-hole applications.
Ideal for heavy-duty drilling in wood, plastic, and soft metals.
