• TRUE M35 GRADE COBALT STEEL: Manufactured from premium High-Speed Steel containing 5% Cobalt (HSS-Co), these bits are heat-hardened to cut through tough abrasive materials. They offer significantly higher heat resistance and wear durability compared to standard HSS bits, making them the ultimate choice for drilling into stainless steel, cast iron, and titanium alloys.
• PRECISION 135° SPLIT POINT: Equipped with a 135-degree self-centering split point, these bits bite into the material immediately upon contact. This active cutting tip prevents "walking" or wandering across the work surface and eliminates the need for a pre-punch pilot hole, ensuring accurate and clean starts every time.
• FULLY GROUND & EFFICIENT: Unlike roll-forged alternatives, our bits are fully ground for precise dimension accuracy and concentricity. The precision-engineered dual twist flute design ensures rapid chip removal, effectively reducing friction and heat buildup for a smoother, cooler drilling process.
• 15PC METRIC SIZE COVERAGE: This comprehensive metric set includes 15 essential sizes: 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6, 6.5, 7, 8, 9, and 10mm. It is a versatile kit suitable for a wide range of projects in metalworking, automotive repair, and general DIY on wood, plastic, aluminum, and hard metals.
• HEAVY-DUTY INDEXED CASE: The bits are housed in a rugged, impact-resistant ABS plastic case with rubberized corners for extra protection. The case features a folding design with clearly marked size indexes (raised lettering) for easy identification, keeping your tools organized, secure, and ready for transport to any job site.
