The Hymnorq 15-Piece M35 Cobalt Drill Bit Set is engineered for professionals and serious DIY enthusiasts who demand performance and durability. Crafted from M35 High-Speed Steel with 5% Cobalt, these bits are specifically designed to withstand high heat and abrasion, making them the perfect solution for drilling through hardened steel, cast iron, and stainless steel.Key Features:Industrial Grade Material: The 5% Cobalt formula significantly improves red hardness, allowing the bits to maintain their cutting edge even at high temperatures generated by metal drilling.No Walking, No Skating: The 135° Split Point tip centers itself immediately, allowing you to drill straight, accurate holes without using a center punch.Professional Construction: Fully ground form ensures straight drilling and precise hole diameters (DIN 338 Standard Jobber Length).Wide Compatibility: While they excel at cutting hard metals, they perform exceptionally well on soft metals (copper, aluminum, brass), wood, and plastics.Specification: Material: HSS M35 Cobalt (5%) Shank Type: Straight Round Shank Point Angle: 135 Degree Split Point Process: Fully Ground Hardness: Rockwell 65-67 HRCSize Included (Metric): 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 8mm, 9mm, 10mm.Package Content: 1 x 15-Piece M35 Cobalt Drill Bit Set 1 x Heavy Duty ABS Storage CaseNote: For maximum longevity when drilling hardened metals, the use of cooling fluid/oil is recommended to keep the bit temperature down. Review: Migiwata 15 Piece Metric M35 Cobalt HSS Drill Bit Ki - This is the best drill bit for drilling out stainless steel screw which is very hard metal. Do not buy the titanium coated for hard steel they go blunt in second. Review: Nice drill bits - Just what i was looking for to drill into stainless steel..! ## 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.

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. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07B7L6WVY | | Best Sellers Rank | 914,557 in DIY & Tools ( See Top 100 in DIY & Tools ) 1,439 in Jobber Drill Bits | | Brand | Hymnorq | | Customer Reviews | 4.4 out of 5 stars 2,451 Reviews | | Cutting Angle String | 135 Degrees | | Cutting Diameter | 10 Millimetres | | Cutting angle string | 135 Degrees | | Cutting diameter | 10 Millimetres | | Finish Types | Bronze | | Finish type | Bronze | | Included Components | 15 pieces of metric cobalt drill bits | | Item Dimensions | 15 x 11 x 4 centimetres | | Manufacturer | Hymnorq | | Manufacturer Part Number | B07B7L6WVY | | Material | Cobalt Steel | | Minimum Bore Diameter | 1.5 Millimetres | | Model Number | B07B7L6WVY | | Number of Flutes | 2 | | Number of Pieces | 15 | | Point Style | Split Point | | Set Name | 15PC Set | | Shank Type | Straight | | Shank type | Straight | | Surface Recommendation | Metal | | Tool Flute Type | Spiral | | UPC | 666389162076 | | Unit Count | 1.0 count | ## Product Details - **Cutting angle string:** 135 Degrees - **Cutting diameter:** 10 Millimetres - **Finish type:** Bronze - **Material:** Cobalt Steel - **Shank type:** Straight ## Images ![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 - Image 1](https://m.media-amazon.com/images/I/71l9S-EuYuL.jpg) ![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 - Image 2](https://m.media-amazon.com/images/I/61HmBLcFGAL.jpg) ![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 - Image 3](https://m.media-amazon.com/images/I/71Wqhf9Um6L.jpg) ![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 - Image 4](https://m.media-amazon.com/images/I/81-5cQC6ZcL.jpg) ![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 - Image 5](https://m.media-amazon.com/images/I/710zRKzE6QL.jpg) ## Available Options This product comes in different **Style** options. ## 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Migiwata 15 Piece Metric M35 Cobalt HSS Drill Bit Ki *by J***N on 3 January 2019* This is the best drill bit for drilling out stainless steel screw which is very hard metal.
