Hymnorq 13-Piece M35 Cobalt Drill Bit Set, Metric 2mm-8mm, HSS Jobber Twist Drill Bits for Hard Metal, Stainless Steel, Cast Iron, Wood, 135° Split Point, Fully Ground with DIN 338 Standard

PREMIUM M35 COBALT STEEL - Manufactured from High-Speed Steel with 5% Cobalt (M35 Grade), these bits exhibit superior heat resistance and durability compared to standard HSS bits. Engineered specifically to cut through hard abrasive materials such as stainless steel, cast iron, and high-temperature alloys without dulling quickly. PRECISION 135° SPLIT POINT - Features a heavy-duty 135-degree split point tip that self-centers immediately upon contact. This design eliminates "walking" or skating across the work surface, ensuring accurate pilot holes and requiring less pressure to penetrate tough metals. FULLY GROUND METRIC SIZES - This set includes 13 specific metric sizes: 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6, 6.5, 7, 7.5, and 8mm. Each bit is fully ground to meet DIN 338 standards, providing precise diameter accuracy and faster chip removal through the dual twist flutes. PROFESSIONAL PERFORMANCE - The golden bronze oxide finish not only provides a sleek professional look but also increases wear resistance and lubricity. Ideal for DIY projects, maintenance, and metalworking where precision drilling in hard metals, wood, and hard plastics is required. ORGANIZED STORAGE CASE - Comes housed in a durable, labeled plastic index case. Each slot is marked with the corresponding metric size for quick identification and easy organization, keeping your bits secure and portable for job site use.
