Cobalt Drill Bits (20PCS) for Hardened Metal, Stainless Steel, Cast Iron, Plastic and Wood

The 20PCS 3/16" Cobalt Drill Bits set is designed to meet the needs of a wide range of power drill users on the current market. Each drill bit measures 3/16" in drilling diameter, 2-5/16" in flute length, and 3-1/2" in overall length.

Crafted from industry-grade M35 high-speed steel, these drill bits are harder and more durable than the 4241 HSS (High-Speed Steel) used in many similar sets. The addition of 5% cobalt further enhances the wear-resistance and longevity of these tools.

The drill bits feature a fully ground spiral groove design that efficiently clears particles, reducing friction and heat for faster and cooler drilling performance. The 135-degree split point with a straight shank helps prevent walking, ensuring precise and speedy drilling without the need for a center punch.

These versatile drill bits are suitable for cutting through a variety of materials, including hard metals such as stainless steel, steel, sheet metal, and cast iron, as well as softer materials like plastic, aluminum alloy, and wood. However, it is essential to exercise caution and maintain proper speed, pressure, and heat control during the drilling process.

Backed by a 90-day warranty, the 20PCS 3/16" Cobalt Drill Bits set offers a reliable and high-quality solution for your drilling needs. If you are not fully satisfied for any reason, the manufacturer encourages you to contact them for a 100% refund or replacement.

In summary, this drill bit set combines the durability of M35 high-speed steel with the added strength of cobalt, delivering a versatile and efficient tool for a wide range of applications. The thoughtful design and warranty further enhance the value and appeal of this product.
