Premium 1/2 Reduced Shank Drill Bit Set for Professionals

The EFFICERE 8-Piece Silver and Deming Drill Bit Set is the perfect choice for drilling large holes over half an inch in diameter on a wide range of materials, including wood, plastic, aluminum, copper, cast iron, mild steel, stainless steel, and sheet metals. Constructed from premium cobalt high-speed steel, these drill bits are built to last and serve a variety of applications, such as woodworking, auto repairs, equipment and machinery, and metal fabrication.

Featuring a 135-degree split point at the tip, the drill bits start cutting with self-centering, providing faster speed and preventing walking during drilling. The superior golden titanium and black nitride dual coating finish applied to each drill bit holds up lubricant better for smoother drilling and is 80% more durable and corrosion-resistant than regular black enamel finish.

The tools have a universal 1/2-inch reduced shank with a tri-flat end that securely locks onto the 3-jaw chuck from all brands of drill presses and power tools, ensuring a secure and stable operation.
