The EFFICERE 8-Piece Silver and Deming Drill Bit Set is the perfect choice when it comes to drilling large holes with a diameter over half an inch. This set can be used on various materials such as wood, plastic, aluminum, copper, cast iron, mild steel, stainless steel, sheet metals, and more.

Not only that, but this set also serves a wide range of applications including woodworking, auto repairs, equipment and machinery, metal fabrication, and many others.

What sets these drill bits apart is their construction from premium cobalt high-speed steel, which provides reliable strength and ensures their durability. The 135-degree split point at the tip allows for faster cutting and self-centering, eliminating the risk of walking during drilling.

To enhance performance and longevity, each drill bit is coated with a superior golden titanium and black nitride dual coating finish. This not only holds up lubricant better for smoother drilling but also makes them 80% more durable and corrosion-resistant compared to regular black enamel finishes.

Additionally, all the tools in this set have a universal 1/2 inch reduced shank with a tri-flat end. This design ensures a secure lock onto the 3-jaw chuck of any brand of drill press or power tool.

The key features of this product include its premium M2 cobalt high-speed steel construction, a 135° split point for efficient drilling without walking, a twist blade with a deep groove design to clear out chips and particles quickly, compatibility with all drill presses and most power tools, a unique tri-flatted shank end for secure locking onto a 3-jaw chuck, and an aluminum case for easy organization and storage.
