Factory High Stainless Steel Twist Drill Bit M35 Cobalt Containing Drilling Bits

Premium-Grade Material for Unmatched Durability
Crafted from high-speed stainless steel infused with M35 cobalt alloy (5% cobalt content), these twist drill bits are engineered to withstand extreme heat and wear, making them ideal for drilling into hardened metals, stainless steel, cast iron, and other tough materials. The cobalt-enhanced composition ensures superior hardness and red hardness, allowing the bits to maintain sharpness even under prolonged, high-temperature drilling conditions. This durability significantly reduces bit replacement frequency, saving both time and costs in industrial or heavy-duty applications.

Precision-Engineered for Clean, Efficient Drilling
Featuring a precision-ground 135° split point tip, these bits eliminate the need for pre-punching by initiating holes quickly and preventing walking or slippage on smooth surfaces. The optimized flute design enhances chip evacuation, ensuring faster material removal and preventing clogging, which is critical when drilling deep holes or working with abrasive materials. The consistent twist angle guarantees smooth, stable cutting performance, minimizing vibration and delivering precise, burr-free holes with every use.

Versatile Performance Across Industries
From automotive repair and aerospace manufacturing to construction and DIY projects, these M35 cobalt drill bits excel in a wide range of applications. They effortlessly handle high-tensile alloys, titanium, and even heat-treated steels, making them indispensable for professionals seeking reliable performance in demanding environments. The bits are compatible with most standard drill chucks and can be used with handheld drills, drill presses, or CNC machines, offering flexibility for both workshop and on-site tasks.

Factory-Direct Quality Assurance
Produced under strict quality control standards, these drill bits undergo rigorous testing to ensure consistent performance and longevity. Each bit is meticulously polished to resist corrosion and oxidation, extending its service life. Available in a variety of sizes to suit diverse needs, this set is a cost-effective investment for workshops, factories, or hobbyists prioritizing precision and durability.
