Narwhal 1/2" Cobalt Drill Bits (3 Pack) – Industrial Grade M35, 6" Length, 135° Split Point

Narwhal 1/2" Cobalt Drill Bits — engineered for metalworking precision

Meet the Narwhal 1/2" cobalt drill bits, a compact three-pack built for robust metal drilling. Crafted from M35 cobalt alloy, these bits blend wear resistance with reliable cutting edges to help you tackle metalwork tasks with steadier results. The set features 5% cobalt content, a fully ground cutting diameter, and a 135° split point designed to guide the drill with less wandering as you start holes in tougher materials.

With a total length of 6" and a flute length of 4", these bits offer extended reach while maintaining control through deep holes in metal projects. The durable construction is paired with a practical plastic storage case, so you can keep your cobalt drill bits neatly organized and ready for your next job. Whether you’re drilling into stainless steel, hardened steel, cast iron, bronze, or other hard alloys, this set is designed to stand up to regular use in demanding environments.

Key features at a glance:

• 3 pack of 1/2" cobalt drill bits for value and versatility
• 5% cobalt content for improved hardness and wear resistance
• Fully ground for precise diameter control and clean holes
• 135° split point reduces walking and improves start-up in tough materials
• 6" total length with 4" flute length for deeper reach
• Durable plastic storage case protects the bits during transport and storage
• Suitable for drilling into stainless steel, hardened steel, cast iron, bronze, titanium, and more

In everyday shop scenarios, these bits can help you move from rough cuts to neater finishes. The combination of cobalt chemistry and a precision-ground geometry aims to deliver consistent holes while resisting wear through repeated use. While outcomes depend on material and drill pressure, many users find that the 135° point and robust bit geometry facilitate smoother starts and steadier progress, especially when working with harder metals.

Real-life use cases and benefits

• Metal fabrication projects that require durable, reliable drill bits for stainless steel and hardened alloys
• Automotive repairs and maintenance tasks where fast starts and clean holes are valuable
• DIY or hobbyist metalworking where a compact, organized bit set saves time
• Shaping and refining cast iron and bronze components with consistent performance

Narwhal backs this set with a customer-first mindset and USA-based support to help if you ever need assistance. The combination of material science, practical design, and thoughtful packaging makes this trio a practical addition to any metalworking toolkit. Consider the Narwhal 1/2" cobalt drill bits as a possibility for your next drilling task — they’re designed to support your work, not promise guarantees.
