Dewalt Accessories DW1608 Split Point Drill Bit 5/16x12

Product Description

The DEWALT ACCESSORIES DW1608 is a high-speed steel split point drill bit engineered for fast, accurate drilling in metal, wood, and plastic. Measuring 5/16 inches in diameter and 12 inches in length, this bit features a 135-degree split point that starts on contact without walking, reducing the need for a center punch. A 31-degree helix angle controls aggressiveness, keeping the bit from digging too fast through material. Black oxide coating adds wear resistance and extends service life in demanding jobsite conditions. Each package includes 5 bits, making it a practical choice for contractors and maintenance professionals who burn through tooling regularly.

This bit is designed for trade and industrial use across a range of drilling applications. The parabolic flute geometry improves chip ejection when drilling through ferrous and non-ferrous metals, hardwoods, softwoods, and plastics. The extended 12-inch length is suited for deep-hole drilling tasks, structural work, and applications where standard-length bits cannot reach. It is appropriate for use with corded or cordless drill drivers and drill presses in both residential and commercial settings.

Key Features

• 135-degree split point starts on contact for no-walk drilling without a center punch
• 31-degree helix angle reduces over-aggressiveness compared to a true parabolic flute
• Parabolic flute design improves chip ejection in metal and wood drilling
• Black oxide coating provides greater resistance to wear and heat
• Industrial-grade high-speed steel construction for durability under load

Installation Notes

Installation is performed by qualified tradespeople or experienced users familiar with rotary drilling equipment. Secure the bit firmly in the chuck before operation and verify the chuck key is removed before powering on. Use appropriate cutting fluid or lubricant when drilling ferrous metals to reduce heat buildup and extend bit life. Always wear appropriate eye protection and follow applicable OSHA and site safety guidelines when operating drilling equipment.
