Dewalt Accessories DW1627 Drill Bit 7/8 Inch 5 Pack

Product Description

The DEWALT ACCESSORIES DW1627 is a 7/8-inch high speed steel split point drill bit sold in a pack of 5. It features a 135-degree split point tip that starts on contact and eliminates bit walking, reducing the need for a center punch. The parabolic flute design improves chip ejection during drilling through metal, wood, and plastic. A 1/2-inch shank provides solid chuck engagement. The black oxide coating increases surface hardness and extends wear resistance under repeated use. This bit is suited for professional tradespeople and contractors who need consistent, reliable performance across varied materials on the job site.

The DW1627 is designed for drilling in metal, wood, and plastic in both residential and commercial applications. The 31-degree helix angle moderates flute aggressiveness, making it suitable for controlled material removal without over-cutting. The 135-degree split point geometry is especially useful for sheet metal, structural steel, dimensional lumber, and plastic panel work where accurate hole placement matters. Electricians, plumbers, HVAC technicians, and general contractors regularly use bits of this type when running penetrations, mounting hardware, or fabricating brackets in the field.

Installation Notes

Install the bit securely into a 1/2-inch or larger drill chuck, ensuring full shank engagement before tightening. Use appropriate drilling speed for the material being drilled — lower speeds for metal, higher speeds for wood and plastic. Apply steady, consistent pressure and allow the flute geometry to clear chips naturally. Wear appropriate eye protection and secure the workpiece before drilling.
