## Description

Hymnorq 15-Piece M35 Cobalt Drill Bit Set, Metric 1.5 to 10mm, 5% Cobalt HSS for Drilling Hard Metal Stainless Steel Cast Iron, Fully Ground Jobber Length Bits with 135° Split Point Tough Indexed Case - desertcart.com

## Features

- 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.

## Questions & Answers

**Q: Can these drill bits cut through hardened steel or stainless steel?**
A: Yes. M35 grade steel with 5% Cobalt is specifically engineered for high-tensile metals like stainless steel, cast iron, and titanium alloys. For fully hardened steel (HRC > 50), carbide bits are recommended.

**Q: Will these bits fit my standard cordless drill?**
A: Yes. These feature standard round straight shanks. The largest diameter is 10mm, allowing them to fit securely into any standard 3/8-inch (10mm) or 1/2-inch (13mm) drill chuck.

**Q: Do I need to use cutting oil or lubricant?**
A: Highly recommended. While Cobalt is heat-resistant, using cutting fluid significantly reduces friction and heat buildup. This prevents the bit from annealing (softening) and greatly extends its lifespan.

**Q: Do these bits require a center punch to start?**
A: No. These bits feature a 135° Split Point tip. This design is self-centering and cuts immediately upon contact with the metal, preventing the bit from "walking" or skating across the surface.

**Q: Are these bits just coated with Cobalt or solid?**
A: They are solid M35 Cobalt steel throughout, not just coated. Unlike titanium-coated bits that lose effectiveness once sharpened, these maintain their heat resistance and performance even after resharpening.
