CNC precision ensures each bit fits perfectly, reducing cam-out and stripping. The magnetic tip securely grips fasteners, making assembly faster and less frustrating. Unlike generic bits that wear out quickly, these are built for repeated heavy-duty use, ensuring your projects are completed efficiently and accurately. **Ideal for Furniture Assembly & Repairs** — This set is perfect for anyone frequently assembling flat-pack furniture or undertaking DIY repairs. The inclusion of both metric and SAE sizes, along with the 1/4" quick-release shank, makes them compatible with most drills and drivers. If you often work with furniture that requires hex fasteners, this set offers the versatility and reliability needed. Those requiring specialized masonry or wood-boring bits should look elsewhere; this set focuses on hex-drive fasteners. ## How to use 1. Identify the required metric or SAE size by checking the laser-etched markings on each 2-inch bit. Match the bit size precisely to the hex head of the screw or bolt you need to drive. — Select the Correct Bit 2. Insert the 1/4" hex shank firmly into the quick-release chuck of your impact driver or drill. Ensure it is seated securely to prevent slippage during operation. — Insert into Drill/Driver 3. Engage the magnetic tip with the screw head. Apply steady pressure and use your drill or driver to turn the bit, driving the fastener until it is secure. Use appropriate torque settings for the material. — Drive Fastener ## Product details | Field | Value | |---|---| | Primary Material | S2 Alloy Steel | | Heat Treatment | Vacuum High-Frequency Quenching | | Coating | Black Phosphate | | Compatible Tools | Impact drivers, drills with 1/4" quick-release chucks, standard drill chucks | | Fastener Type | Hex head screws and bolts | | Metric Sizes | 1.5mm, 2mm, 2.5mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm | | SAE Sizes | 5/64", 3/32", 7/64", 1/8", 9/64", 5/32", 11/64", 3/16", 13/64", 7/32", 15/64", 1/4", 17/64", 9/32", 19/64", 5/16" | | Cost per use | 20 bits in set: ₹80.00 per bit | | Shelf life after opening | N/A (Durable Tool) | | Contraindications | Not for masonry, concrete, or large-diameter wood boring.

Yes, these 1/4" hex shank drill bits can be used in standard three-jaw drill chucks. While they are designed for impact drivers and quick-release chucks, the hex flats can be securely gripped by a standard chuck, allowing for versatile use across different drill types. ### What materials can these hex shank drill bits be used on? These S2 alloy steel hex shank drill bits are primarily designed for driving screws and bolts with hex heads. They are excellent for working with wood, plastic, and metal fasteners commonly found in furniture assembly and general repairs. They are not intended for drilling holes in masonry or concrete. ### How do I identify the correct metric or SAE size bit? Each PTSLKHN drill bit features clear, laser-etched markings directly on the shaft. These markings indicate the specific metric (e.g., 5mm) or SAE (e.g., 3/16") size, allowing for quick and accurate identification, saving you time during assembly or repair projects. ### Will the magnetic tip hold screws securely during assembly? Yes, the magnetic tip on these PTSLKHN hex shank drill bits is designed to securely hold screws and fasteners. This feature prevents bits from slipping during operation, ensuring a stable connection and reducing the risk of dropped screws, especially in tight or awkward spaces. ### How do the metric and SAE sizes compare for furniture assembly? This set includes 10 metric sizes (1.5mm–8mm) and 10 SAE sizes (5/64"–5/16"), covering a broad range of fastener requirements. This comprehensive selection ensures you have the correct bit for most furniture assembly tasks, whether dealing with European-style or North American-style hardware. ### How to choose the right hex shank drill bit set for furniture assembly? For furniture assembly, look for a set with both metric and SAE sizes, a 1/4" hex shank for compatibility with common drills, and a magnetic tip for ease of use. The PTSLKHN set offers these features, along with durable S2 alloy steel construction, making it a reliable choice for flat-pack furniture and general repairs. ### What is the benefit of S2 alloy steel for drill bits?
