Dewalt 1623 11/16-Inch Black Oxide Reduced Shank Twist Drill Bit

The Dewalt 1623 is a professional-grade 11/16-inch black oxide twist drill bit designed for drilling in metal, wood, and plastic. This bit features a reduced 1/2-inch shank that allows it to be used in standard 1/2-inch drill chucks while providing the cutting diameter of a larger 11/16-inch bit.

Key Features:

• 11/16-inch drilling diameter for versatile applications
• 1/2-inch reduced shank fits standard drill chucks
• Black oxide coating reduces friction and resists corrosion
• High-speed steel (HSS) construction for durability and heat resistance
• 135-degree split point tip starts on contact with no walking
• Ideal for metalworking, woodworking, and general construction tasks

The black oxide finish helps extend bit life by providing lubricity and preventing rust during storage. The reduced shank design eliminates the need for larger drill chucks while maintaining full cutting performance, making this an economical choice for contractors and DIY users alike.
