NOTE: color is random - FEATURE: Our carbide twist drills combine ​92% Tungsten Carbide / ​​8% Cobalt for extreme hardness (HRA 89-95), wear resistance (3x HSS life), and heat stability (800°C+). Featuring razor-sharp cutting edges and precise milling grooves, ensuring maximum productivity and durability in demanding applications. - APPLICATION: With their high hardness, wear resistance, and precision machining capabilities, cemented carbide mini drill bits are widely used in high-precision applications, including electronics manufacturing (PCB micro-hole drilling), precision machinery (micro-component processing, micro-hole machining) - INSTRUCTION: Make sure the workpiece is firmly clamped (such as using a vise or fixture) to prevent it from sliding during drilling. Position the twist drill at 90° to the workpiece. For thick materials, drill in multiple passes to prevent overheating or breakage. - NOTE: When machining different materials, the spindle speed and feed rate vary. Generally, the harder the material, the lower the spindle speed and feed rate should be. Always use coolant in high-speed machining to protect carbide tools from heat-induced failure. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0FSZJLK6K | | Best Sellers Rank | #18,672 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #4 in Circuit Board Drill Bits #427 in Drill Bits | | Brand | PATIKIL | | Brand Name | PATIKIL | | Customer Reviews | 4.5 out of 5 stars 44 Reviews | | Cutting Angle String | 135 Degrees | | Finish Type | Uncoated | | Finish Types | Uncoated | | Included Components | not_applicable | | Manufacturer | PATIKIL | | Material | Tungsten Carbide | | Material Type | Tungsten Carbide | | Number of Flutes | 2 | | Number of Pieces | 40 | | Part Number | ptf250707tt000071 | | Shank Type | Straight | | Surface Recommendation | Metal, Plastic, Wood | | Tool Flute Type | Spiral | | Unit Count | 1.0 Count | ## Images ![PATIKIL 40Pcs 0.1mm-1mm Micro Drill Bits Set Carbide Tungsten Steel 135° Mini Small Bits Print Circuit Board Drilling Tool for CNC Engraving Precision Machinery - Image 1](https://m.media-amazon.com/images/I/61sOuFJNx3L.jpg) ![PATIKIL 40Pcs 0.1mm-1mm Micro Drill Bits Set Carbide Tungsten Steel 135° Mini Small Bits Print Circuit Board Drilling Tool for CNC Engraving Precision Machinery - Image 2](https://m.media-amazon.com/images/I/71Vt7qeehrL.jpg) ![PATIKIL 40Pcs 0.1mm-1mm Micro Drill Bits Set Carbide Tungsten Steel 135° Mini Small Bits Print Circuit Board Drilling Tool for CNC Engraving Precision Machinery - Image 3](https://m.media-amazon.com/images/I/61VF1PPbg4L.jpg) ![PATIKIL 40Pcs 0.1mm-1mm Micro Drill Bits Set Carbide Tungsten Steel 135° Mini Small Bits Print Circuit Board Drilling Tool for CNC Engraving Precision Machinery - Image 4](https://m.media-amazon.com/images/I/615+xHKSjbL.jpg) ![PATIKIL 40Pcs 0.1mm-1mm Micro Drill Bits Set Carbide Tungsten Steel 135° Mini Small Bits Print Circuit Board Drilling Tool for CNC Engraving Precision Machinery - Image 5](https://m.media-amazon.com/images/I/716fHtAxaXL.jpg) ## Available Options This product comes in different **Size, Number Of Items** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by J***N on March 10, 2026* ### ⭐⭐⭐⭐⭐ Review *by T***S on April 1, 2026* ### ⭐⭐⭐⭐ Review *by C***E on April 12, 2026* --- ## 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.kr/products/807729958-patikil-40pcs-0-1mm-1mm-micro-drill-bits-set-carbide](https://www.desertcart.kr/products/807729958-patikil-40pcs-0-1mm-1mm-micro-drill-bits-set-carbide) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-06-05*
