Dewalt Accessories DW1606 Split Point Drill Bit 5 Pack

Product Description

The DEWALT ACCESSORIES DW1606 is a high speed steel, split point drill bit designed for professional drilling in metal, wood, and plastic. At 1/4 inch in diameter and 12 inches in length, this bit is built for deep-hole applications where reach and control matter. The 135-degree split point delivers a quick, no-walk start on contact, eliminating the need for a center punch in most situations. A 31-degree helix angle moderates the aggressiveness of the parabolic flute geometry, keeping the bit stable and predictable in varying materials. A black oxide coating is applied to reduce friction and extend wear resistance over repeated use. Licensed trades, general contractors, and experienced DIYers rely on this bit for demanding jobsite work.

This drill bit is suited for residential and light commercial applications where a long-reach, general-purpose bit is needed. The parabolic flute design promotes efficient chip ejection when boring through ferrous and non-ferrous metals, hardwoods, softwoods, and plastics. It is packaged in a quantity of 5 per unit, making it practical for shop stock or kit replenishment. Typical install scenarios include electrical rough-in, mechanical trades requiring clearance holes, and woodworking or fabrication work where a standard 3/8-inch or 1/2-inch chuck drill press or hand drill is used.

Installation Notes

Ensure the drill or drill press is powered off and unplugged before inserting or removing the bit from the chuck. Secure the workpiece before drilling to prevent movement and reduce the risk of bit breakage or injury. Use cutting fluid or cutting oil when boring through ferrous metals to extend bit life and improve hole quality. Inspect the split point for chipping or wear before each use and replace any damaged bits promptly.
