The DWD29J-CO-PC 29-piece M35 cobalt drill bit set is perfect for tough materials like stainless steel, Inconel, and titanium. M35 cobalt offers superior heat resistance and red hardness compared to standard high-speed steel (HSS), enabling drilling speeds up to 30% faster without sacrificing performance. Manufactured to Aerospace Standard 907, these bits deliver professional-grade precision and reliability. The 135-degree split-point tip ensures self-centering and reduces thrust, preventing “walking” and allowing for accurate drilling, even in challenging applications. Housed in a durable round plastic case, the set combines practicality and style. The case is rust-resistant, water-proof, and shatter-proof, ensuring long-lasting protection for your bits. Its compact, lightweight design makes it easy to organize and transport, ideal for professionals on the go.
