DEWALT 1610 High-Speed Steel Drill Bit 3/8-Inch x 12-Inch Black Oxide

The DEWALT 1610 is a professional-grade high-speed steel (HSS) drill bit designed for deep drilling applications. Measuring 3/8-inch in diameter and 12 inches in length, this extra-long drill bit is ideal for drilling through thick materials where standard-length bits fall short.

Key Features:

• Black oxide coating provides rust resistance and reduces friction for smoother drilling
• High-speed steel construction delivers durability and heat resistance
• 3/8-inch diameter suitable for medium to large hole applications
• 12-inch extended length reaches deep into thick stock and beams
• 135-degree split point tip starts on contact with minimal walking
• Parabolic flute design efficiently clears chips and debris

This extended-length drill bit is commonly used in construction, electrical work, plumbing, and woodworking applications where standard bits cannot reach. The black oxide finish extends tool life while maintaining sharp cutting edges through repeated use in wood, plastic, and metal materials.
