The 5-percent alloy is known as M35 grade. The cobalt increases the strength of the steel and makes it more heat-resistant. 3. Jobber length twist drill bit's hardess is uniform throughout the entire material, so that can be repeatedly sharpened without damaging the cutting edge allowing it to drill more than hss drill bits. How to Use Twist Drill Bits? 1. Ensure the left and right cutting edges of the drill are symmetrical when drilling. 2. Observe the uniformity of the spark while drilling, adjust the pressure in time, and pay attention to the cooling of the bit. 3. Mini twist drill bit can NOT be used in the impact drill. 4. Please use with cooling liquid to prolong the working life of the drill bits and to avoid overheating and breakage. 5. Drilling metal is recommended for use on bench drills. 6. Hand drills are suitable for drilling low hardness materials.Kindly Note: Please allow 1-2mm errors due to manual measurement, thank you for your understanding! ## Features - Specification - 10Pcs 3mm cobalt drill bits, each kit contains a total of ten drill bits in the same size, Blade length: 33mm/1.3inch, 135 degree point, straight shank. - Material - HSS Cobalt high speed steel for super abrasive resistance in tough metals, improve much higher heat resistance because of cobalt steel's high red hardness. - Long-lasting - M35 HSS Drill Bit provide sturdy performance compared to typical hss drill bits. - Easy to Carry - The M35 jobber length twist drill bits are housed in plastic case for easy storage, easy to carry out homework. - Multi-purpose Use - Straight Shank M35 Drill Bits are successful in cutting hard metals such as stainless steel, copper, aluminum alloy, and also can be used for softer materials. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07PRV5DNS | | ASIN | B07PRV5DNS | | Best Sellers Rank | #90,527 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #86 in Jobber Drill Bits | | Brand Name | Sipery | | Customer Reviews | 4.5 4.5 out of 5 stars (128) | | Customer reviews | 4.5 4.5 out of 5 stars (128) | | Cutting Angle String | 118 Degrees | | Cutting Diameter | 3 Millimeters | | Date First Available | 19 March 2021 | | Finish Types | Cobalt | | Item Weight | 0.1 Kilograms | | Item model number | M35 cobalt drill bit | | Manufacturer | Sipery | | Manufacturer | Sipery | | Material Type | High Speed Steel M35(HSS-M35) with Cobalt | | Minimum Bore Diameter | 3 Millimeters | | Model | M35 cobalt drill bit | | Number of Flutes | 2 | | Number of Pieces | 10 | | Package Dimensions | 6.6 x 2.8 x 0.5 cm; 100 g | | Part Number | 3mm Jobber Drill Bits Set | | Point Style | Taper Point | | Set Name | 10-Piece Set | | Shank Type | Straight | | Surface Recommendation | Metal | | Tool Flute Type | Spiral | | UPC | 610895309845 | | Unit Count | 10 Count | ## Product Details - **Cutting angle string:** 118 Degrees - **Cutting diameter:** 3 Millimeters - **Finish type:** Cobalt - **Material:** High Speed Steel M35(HSS-M35) with Cobalt - **Shank type:** Straight ## Images ![10Pcs M35 Cobalt HSS Twist Drill Bits 3mm with Straight Shank, Drilling for Stainless Steel, Copper, Aluminum Alloy and Softer Materials - Image 1](https://m.media-amazon.com/images/I/71-wY9JEXTL.jpg) ![10Pcs M35 Cobalt HSS Twist Drill Bits 3mm with Straight Shank, Drilling for Stainless Steel, Copper, Aluminum Alloy and Softer Materials - Image 2](https://m.media-amazon.com/images/I/612iwR+XrpL.jpg) ![10Pcs M35 Cobalt HSS Twist Drill Bits 3mm with Straight Shank, Drilling for Stainless Steel, Copper, Aluminum Alloy and Softer Materials - Image 3](https://m.media-amazon.com/images/I/71SqybwcZkL.jpg) ![10Pcs M35 Cobalt HSS Twist Drill Bits 3mm with Straight Shank, Drilling for Stainless Steel, Copper, Aluminum Alloy and Softer Materials - Image 4](https://m.media-amazon.com/images/I/71tScON14tL.jpg) ![10Pcs M35 Cobalt HSS Twist Drill Bits 3mm with Straight Shank, Drilling for Stainless Steel, Copper, Aluminum Alloy and Softer Materials - Image 5](https://m.media-amazon.com/images/I/71iQT43oEhL.jpg) ## Available Options This product comes in different **Size** options. ## Frequently Bought Together - Sipery 1/8" Cobalt Drill Bit Set 3mm M35 HSS Steel Twist Drill Bits for Hard Metal and Stainless Steel 10 Pack - Cobalt Drill Bit Set 4mm - 10pcs, M35 Twist Drill Bits Straight Shank, 4mm High Speed Steel Drill Bits for Drilling in Hard Metal, Stainless Steel, Cast Iron - Hymnorq 10-Piece M35 Cobalt Steel Drill Bit Set for Metals, 4.2mm Metric, Fully Ground, 135° Split Point, Bronze Finish, DIN338 Standard, in Tough Transparent PP Case --- ## 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.co.za/products/696043827-10pcs-m35-cobalt-hss-twist-drill-bits-3mm-with-straight](https://www.desertcart.co.za/products/696043827-10pcs-m35-cobalt-hss-twist-drill-bits-3mm-with-straight) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-07-05*
