Unlike standard HSS bits that dull quickly when facing hard alloys, our bits are infused with 5% Cobalt, creating a heat-resistant, hardened structure capable of penetrating stainless steel and cast iron with ease.Key Features:True M35 Grade Cobalt: Not just a surface coatingβ€”these bits are made from a solid cobalt-steel alloy that withstands extreme heat and abrasion, extending tool life by up to 12x compared to standard bits.No-Slip Starting: The 135Β° split point tip bites into the material instantly. You get precise holes exactly where you marked them, without the bit skating across the surface.Versatile Metric Sizes: This set covers the essential small-to-medium range, including the commonly used 3.2mm and 4.8mm sizes, making it a versatile addition to any toolbox.Technical Specifications:Material: HSS-Co 5% (M35 Grade)Point Angle: 135 Degree Split PointProcess: Fully GroundShank Type: Straight Round ShankHardness: Rockwell 65-67 HRCIncluded Sizes (mm): 1.5mm, 2.0mm, 2.5mm, 3.0mm, 3.2mm, 3.5mm, 4.0mm, 4.5mm, 4.8mm, 5.0mm, 5.5mm, 6.0mm, 6.5mmProfessional Usage Tips: For maximum longevity when drilling hardened metals like stainless steel, we recommend using a lower RPM and applying cutting fluid or oil to keep the bit cool.Package includes 13 drill bits in a labeled plastic index case. Review: Arrived on time and got what I expected. Very happy Review: 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. ## Features - PREMIUM M35 COBALT STEEL – Crafted from High-Speed Steel containing 5% Cobalt (M35 Grade). This hardened alloy ensures superior heat resistance and durability compared to standard HSS bits, measuring up to 67 Rockwell Hardness. Ideal for drilling through tough, high-tensile materials like stainless steel, cast iron, and titanium alloys. - PRECISION 135Β° SPLIT POINT – Features a fully ground 135-degree split point geometry that self-centers immediately upon contact. This active cutting tip penetrates faster with less pressure and eliminates "walking" or wandering across the work surface, removing the need for a pre-punch. - 13-PIECE METRIC SELECTION – Includes a carefully selected range of metric sizes for precision work: 1.5, 2, 2.5, 3, 3.2, 3.5, 4, 4.5, 4.8, 5, 5.5, 6, and 6.5mm. Note: Includes useful intermediate sizes 3.2mm (approx. 1/8") and 4.8mm (approx. 3/16") for specialized fitting requirements. - EFFICIENT & CLEAN DRILLING – The fully ground dual twist flute design ejects chips rapidly, reducing friction and heat accumulation. This preserves the drill bit's life and ensures smooth, accurate holes without burrs, even during heavy-duty continuous use. - ORGANIZED STORAGE – Comes packed in a labeled, durable plastic index case (marked with HSS-drills). The inner holder tilts out for easy access and keeps bits organized by size, making it perfect for transport to job sites or keeping your workbench tidy. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B071ZRMWBN | | Best Sellers Rank | #182,677 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #162 in Jobber Drill Bits | | Brand | Hymnorq | | Country of Origin | USA | | Cutting Angle String | 135 Degrees | | Finish Type | Titanium | | Included Components | 13 pieces of metric cobalt drill bits | | Item Dimensions LxWxH | 13 x 1.5 x 7 Centimeters | | Item Weight | 100 g | | Item dimensions L x W x H | 13 x 1.5 x 7 Centimeters | | Item model number | DC023 | | Manufacturer | Hymnorq | | Material | Cobalt Steel | | Net Quantity | 1.0 Count | | Number of Flutes | 2 | | Number of Pieces | 13 | | Point Style | Split Point | | Product Dimensions | 13 x 1.5 x 7.01 cm; 100 g | | Shank Type | Straight | | Surface Recommendation | Alloy Steel | | Tool Flute Type | straight,twist | | UPC | 610521863130 | ## Product Details - **Brand:** Hymnorq - **Cutting Angle String:** 135 Degrees - **Finish Type:** Titanium - **Material:** Cobalt Steel - **Shank Type:** Straight ## Images ![Migiwata Metric M35 Cobalt Steel Extremely Heat Resistant Twist Drill Bits with Straight Shank Set of 13pcs to Cut Through Hard Metals Such as Stainless and Cast Iron - Image 1](https://m.media-amazon.com/images/I/41B4pZbeNAL.jpg) ![Migiwata Metric M35 Cobalt Steel Extremely Heat Resistant Twist Drill Bits with Straight Shank Set of 13pcs to Cut Through Hard Metals Such as Stainless and Cast Iron - Image 2](https://m.media-amazon.com/images/I/41EDbzanKIL.jpg) ![Migiwata Metric M35 Cobalt Steel Extremely Heat Resistant Twist Drill Bits with Straight Shank Set of 13pcs to Cut Through Hard Metals Such as Stainless and Cast Iron - Image 3](https://m.media-amazon.com/images/I/51H8B0BejNL.jpg) ![Migiwata Metric M35 Cobalt Steel Extremely Heat Resistant Twist Drill Bits with Straight Shank Set of 13pcs to Cut Through Hard Metals Such as Stainless and Cast Iron - Image 4](https://m.media-amazon.com/images/I/51KPoNST+IL.jpg) ![Migiwata Metric M35 Cobalt Steel Extremely Heat Resistant Twist Drill Bits with Straight Shank Set of 13pcs to Cut Through Hard Metals Such as Stainless and Cast Iron - Image 5](https://m.media-amazon.com/images/I/51Rpd4lM+FL.jpg) ## Questions & Answers **Q: how long are those?** A: Thanks for your question. We just measured all the bits. Length of Dia. 6.5mm drill bit: 100mm Length of Dia. 6mm drill bit: 92mm Length of Dia. 5.5mm drill bit: 93mm Length of Dia. 5mm drill bit: 86mm Length of Dia. 4.8mm drill bit: 86mm Length of Dia. 4.5mm drill bit: 79mm Length of Dia. 4mm drill bit: 74mm Length of Dia. 3.5mm drill bit: 69mm Length of Dia. 3.2mm drill bit: 65mm Length of Dia. 3mm drill bit: 62mm Length of Dia. 2.5mm drill bit: 55mm Length of Dia. 2mm drill bit: 48mm Length of Dia. 1.5mm drill bit: 39mm **Q: I need to cut through 3/16" heat treated high carbon steel. Think these can handle it?** A: Carbide bits are suitable for heat treated high carbon steel and hardened steel. **Q: Can these drill through cheddar or provolone without breaking?** A: Keep the speed very low or you risk burning the medium. You can go as low as 1RMM or even less. Or just chuck up a pit and poke at 0RPM. It works surprisingly well! If you wish to minimize the likelihood of burning, use a full-fat cheese for extra lubrication. Avoid drilling Swiss cheese if possible. The Swiss have used a clever proprietary blind hole drilling process during the manufacturing of their cheese and those pre-drilled holes definitely cause the bit to wander off course if the cheese is subsequently drilled outside of the factory setting. I learned that the hard way. Getting back to your original question, if you drill perpendicular to the face and slowly, you should be ok. I haven't tried it any other way tho, to be honest. By the nature of your question, I presume you are in Wisconsin. Go Packers! **Q: Why do drill bits sometimes break when drilling?** A: 1. Poor quality of bit. 2. Too much pressure on the drill and it either heats up and snaps or the point grabs and the bit twists and breaks. 3. Not going straight through and pushing sidewise on the bit. If you believe that you operate properly but the the bits break, please contact us for a few replacement. You can always buy with confidence from Migiwata. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by M***E on 10 January 2026* Arrived on time and got what I expected.
