Its 135° split-point design reduces walking for precise drilling in hard metals, hardwoods, and composites. With 3-5 times longer lifespan than standard bits, it’s engineered for high-efficiency machining and detailed woodworking, making it an essential tool for professionals and serious DIYers alike. ## Description Product Description ## Features - 1- PACKAGE CONTENTS - 1 pack of 6.7mm drill bits, with a 100mm (3.94") overall length and 50mm (1.97") flute length, featuring a 135° split-point angle for reduced walking and enhanced drilling accuracy in metal, wood, and plastic applications. - 2- MATERIAL - M42 cobalt high-speed steel drill bits, with a cobalt content 8%, deliver superior hardness and durability. Known for outstanding wear and heat resistance, as well as high crack resistance, these bits excel in drilling high-strength and difficult-to-machine metals. The titanium nitride (tin) coating enhances surface characteristics, boosting wear and corrosion resistance. This treatment contributes to prolonged tool lifespan and improved operational efficiency. - 3- APPLICATION - For precision drilling in hard metals, hardwoods, composite boards, and carved components, these bits efficiently process dense woods like rosewood and teak. The cutting edges maintain exceptional sharpness even at high RPM, making them perfect for detailed craft carving, mortise-and-tenon joinery, and thin wood sheet drilling - the ultimate tool for woodworking DIY, furniture manufacturing, and artistic carving applications. - 4- HIGH EFFICIENCY - Cobalt high-speed steel extended service life & reduced wear. Compared to standard HSS drill bits, it offers a 3–5 times longer tool life, significantly lowering the cost per hole. High-efficiency production​​: Its balanced wear resistance and toughness ensure reliable performance in automated equipment and high-volume machining. - 5- TAKE NOTICE OF - Position the twist drill perpendicular (90°) to the workpiece surface. Begin drilling at low RPM (500-800) to establish a small hole, then adjust speed based on material: higher for wood, lower for metals. Use cutting fluid to effectively reduce temperature, minimize wear, and extend drill bit life ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0FYC7MHWF | | Best Sellers Rank | 439,191 in DIY & Tools ( See Top 100 in DIY & Tools ) 441 in Jobber Drill Bits | | Brand | Kozelo | | Country Of Origin | China | | Finish Types | Titanium Nitride | | Finish type | Titanium Nitride | | Included Components | not_applicable | | Manufacturer | Kozelo | | Material | Cobalt Steel | | Shank Type | Straight | | Shank type | Straight | | Tool Flute Type | Spiral | | Tool flute type | Spiral | | Unit Count | 1.0 count | | Unit count | 1.0 count | ## Images ![1pcs Drill Bit - [6.7mm Diameter] M42 8% Cobalt HSS Cutting Tool for Machining Hard Metal Stainless Steel Woodworking Handicraft Use, 135° Cutting Angle TiN - Image 1](https://m.media-amazon.com/images/I/41h+YsOm0YL.jpg) ![1pcs Drill Bit - [6.7mm Diameter] M42 8% Cobalt HSS Cutting Tool for Machining Hard Metal Stainless Steel Woodworking Handicraft Use, 135° Cutting Angle TiN - Image 2](https://m.media-amazon.com/images/I/71pbD6j6f-L.jpg) ![1pcs Drill Bit - [6.7mm Diameter] M42 8% Cobalt HSS Cutting Tool for Machining Hard Metal Stainless Steel Woodworking Handicraft Use, 135° Cutting Angle TiN - Image 3](https://m.media-amazon.com/images/I/71BYoBcBmjL.jpg) ![1pcs Drill Bit - [6.7mm Diameter] M42 8% Cobalt HSS Cutting Tool for Machining Hard Metal Stainless Steel Woodworking Handicraft Use, 135° Cutting Angle TiN - Image 4](https://m.media-amazon.com/images/I/71j+MtxmoJL.jpg) ![1pcs Drill Bit - [6.7mm Diameter] M42 8% Cobalt HSS Cutting Tool for Machining Hard Metal Stainless Steel Woodworking Handicraft Use, 135° Cutting Angle TiN - Image 5](https://m.media-amazon.com/images/I/71yI0KPQooL.jpg) --- ## 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.sc/products/814341502-1pcs-drill-bit-6-7mm-diameter-m42-8-cobalt-hss](https://www.desertcart.sc/products/814341502-1pcs-drill-bit-6-7mm-diameter-m42-8-cobalt-hss) --- *Product available on Desertcart Seychelles* *Store origin: SC* *Last updated: 2026-07-14*
