IRWIN Cobalt Drill Bit Set, 29 Pieces (3018002)

The IRWIN Tools Cobalt Alloy Steel High-Speed Steel Drill Bit, 29-Piece Metal Index Set (3018002) is perfect for drilling in tough metal, such as heavy-duty abrasive alloy metal drilling on hardened steel. It is made from industrial grade high-speed steel, which ensures increased durability. The drill bits are constructed using heavy duty web construction for strength and durability, and the 5% cobalt alloy steel material provides higher heat and abrasion resistance.

With a 135-degree split-point tip, these drill bits start drilling immediately with less force and eliminate the issue of "walking" across the work surface. The set includes drill bit sizes ranging from 1/16 to 1/2-inch, in 1/64-inch increments, providing a wide range of options for various drilling needs.

The set comes with a metal index case, which allows for easy bit access and identification. This makes it convenient to select the right bit for the job. The rubber overmolded case protects the drill bits against damage from accidental dropping, ensuring their long-lasting use. The case also features removable cartridges, allowing you to easily carry the bits from the case to your worksite.

Additionally, the set features a reduced shank above the 3/8-inch point, enabling you to use larger drill bits in a 3/8-inch chuck. This adds to the versatility of the set, making it suitable for a wider range of drilling applications.

In conclusion, the IRWIN Tools Cobalt Alloy Steel High-Speed Steel Drill Bit, 29-Piece Metal Index Set (3018002) is a durable and reliable choice for drilling in tough metal. Its high-quality material and construction ensure long-lasting performance, while the various sizes and convenient case make it easy to use for different applications.
