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 coating—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 135° 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: Quite Impressive - I was impressed first with the fast shipping and also impressed with the drill bits They come in a very nice case and each drill bit has its own numbered slot. Now I have not had a chance to use them yet but they look to be of great quality for the price. I wanted drill bits for drilling steel and these look like they can handle the job. Review: Excellent set of METRIC bits! - At the time I purchased these, I only intended to use them for light duty (drilling into polymer). However, as fate would have it, I had to use them to drill into hardened steel, and much to my surprise, they performed admirably. It was a pleasant surprise (I was expecting "Chinese junk") and I'm very happy with this purchase; especially considering that it's a METRIC set, which is difficult to find (in the USA). I wish the set had a 1mm bit, but oh well. It's just a preference, not anything against the quality of the bits in this set. ============= Update 1/16/18 ============= My rating has changed from 5 stars down to 3. I needed to drill into metal again--actually I wasn't even drilling new holes, but just "chasing" already existing holes to expand them--and neither the 4.5mm or 4.8mm bits would do anything. They just spun around getting hot, without cutting anything. I even tried the 5mm bit, even though that was too big for my purposes, and it also did nothing but spin. Thus, I've used four of the bits (4, 4.5, 4.8, and 5mm), and only one of them did anything. The one that actually worked did its job well; the others are a HUGE disappointment. ============= Update 1/25/18 ============= Kudos to Migiwata customer service (thank you, Bella!). After hearing about my not-so-pleasant experience with these bits, they sent me a second set. Apparently their original supplier had run dry, and they had to use a second, temporary supplier while the original caught up with demand. The first set that I received was from the temporary supplier. The new set is from the original supplier, and the bits seem to be in order in this new set. So how do you tell the difference? By the case (see photos). The set with the blue dot on the case--which is a plastic retainer to keep the case closed--is from the original supplier. Now if you happen to get a set without the blue dot, don't panic. Just because I got a subpar set that slipped through the manufacturer's quality control process doesn't mean that you did, too. Try the bits out first. WORST case is that Migiwata customer service takes care of you like they did me; best case is you don't even have a problem. As for me and my review of this product, I'm a happy camper again and am bumping my rating back up to 5 stars. The bits are great (make sure to use a good cutting lubricant/coolant) and Migiwata customer service is stellar. ## 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 135° 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 | #153,888 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #135 in Jobber Drill Bits | | Brand | Hymnorq | | Brand Name | Hymnorq | | Country of Origin | USA | | Customer Reviews | 4.4 out of 5 stars 1,109 Reviews | | Cutting Angle String | 135 Degrees | | Cutting Diameter | 3 Millimetres | | Finish Type | Titanium | | Finish Types | Titanium | | Included Components | 13 pieces of metric cobalt drill bits | | Item Dimensions | 13 x 1.5 x 7 Centimeters | | Item Weight | 0.1 Kilograms | | Manufacturer | Hymnorq | | Material | Cobalt Steel | | Material Type | Cobalt Steel | | Model Number | DC023 | | Number of Flutes | 2 | | Number of Pieces | 13 | | Part Number | DC023 | | Point Style | Split Point | | Set Name | 13pcs | | Shank Type | Straight | | Surface Recommendation | Alloy Steel | | Tool Flute Type | straight,twist | | UPC | 610521863130 | | Unit Count | 1.0 Count | ## 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/71-BbfYbPlL.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/719JlBB4mOL.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/61HmBLcFGAL.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/81-5cQC6ZcL.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/710zRKzE6QL.jpg) ## 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 6.5mm, 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 ### ⭐⭐⭐⭐⭐ Quite Impressive *by E***N on 20 May 2019* I was impressed first with the fast shipping and also impressed with the drill bits They come in a very nice case and each drill bit has its own numbered slot.

I had problem with a 3mm drill bit, the surface that I tried to drill wasn’t flat, took a bad angle and snapped the bit. Contacted the seller, send me a remplacement right away. That’s excellent service. ## Frequently Bought Together - Hymnorq 13-Piece Cobalt Drill Bit Set with Index Case – M35 Grade (5% Cobalt) Steel, 1.5mm to 6.5mm, Dual Twist Flute, 135° Split Point, Ideal for Hard Metals Like Stainless Steel and Cast Iron - Owl Tools 4.5mm Cobalt Drill Bits - 13 Pack M35 Cobalt Drill Bits with Storage Case - Perfect for Metal, Hardened & Stainless Steel, Cast Iron - M35 5% Cobalt Metric Drill Bits Set (1mm-10mm/19pcs), Straight Shank Jobber Drill Bits, Metal HSS Twist Drill Bits for Stainless Steel Hard Metal and Cast Iron --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/452866193-migiwata-metric-m35-cobalt-steel-extremely-heat-resistant-twist-drill](https://www.desertcart.sn/products/452866193-migiwata-metric-m35-cobalt-steel-extremely-heat-resistant-twist-drill) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-08-27*
