The 6 PCS Combination Drill and Tap Set is a professional-grade tool kit designed to streamline your threading operations. This innovative set combines drilling and tapping into a single, efficient step, eliminating the need to switch between multiple tools. Each bit features a precision-ground drill point followed by a cutting tap, allowing you to drill, tap, and deburr in one continuous operation. Crafted from HSS titanium-coated steel with a 1/4-inch quick-change hex shank, this set delivers exceptional durability, accuracy, and convenience for metalworking, automotive repair, electrical work, and DIY projects.Complete 6-Piece Set with Essential NC Thread SizesThis set includes six combination drill and tap bits covering the most commonly used National Coarse (NC) thread sizes:6-32 NC – Ideal for small fasteners and electronics8-32 NC – Common for appliances and light machinery10-32 NC – Standard for electrical panels and equipment10-24 NC – Popular for general assembly and automotive12-24 NC – Suitable for heavier fastening applications1/4-20 NC – One of the most widely used sizes for construction and automotiveWith these six sizes, you'll be prepared for a wide range of threading tasks in the workshop, job site, or garage.One-Step Drilling and Tapping DesignThe innovative combination design integrates both the drill bit and tap into a single tool, allowing you to drill and tap a hole in one continuous operation. This eliminates the need to switch between multiple tools, saving time and ensuring perfect alignment between the drilled hole and the tapped threads. The result is faster workflow, reduced tool changes, and consistently accurate threading.HSS Titanium Construction for DurabilityEach bit is crafted from high-speed steel (HSS) with a titanium coating, providing exceptional hardness, heat resistance, and wear resistance. The titanium coating reduces friction during drilling and tapping, extending the life of the bits and ensuring clean, precise threads even in tough materials like steel, aluminum, brass, copper, and sheet metal. This durable construction delivers reliable performance for both professional and DIY applications.Integrated Deburring and CountersinkingThe design also incorporates a deburring and countersinking feature that cleans the top edge of the hole as it cuts, eliminating sharp edges and allowing screws and bolts to sit flush with the surface. This saves additional time and ensures a professional, finished appearance without the need for separate deburring tools.1/4-Inch Quick-Change Hex Shank for Universal CompatibilityAll bits feature a standard 1/4-inch quick-change hex shank, making them compatible with most cordless drills, impact drivers, and electric screwdrivers. The quick-change design allows for tool-free bit swaps in seconds, keeping your workflow efficient and uninterrupted. Simply pull back the collar, insert the bit, and you're ready to work.Self-Centering Split Point for Accurate StartingThe precision-ground split-point tip provides self-centering action, preventing wandering and ensuring the bit starts exactly where you want it. This is especially valuable when working on curved surfaces or materials where accurate placement is critical. The split-point design also reduces the amount of pressure needed to start the cut, making operation easier and more controlled.Versatile Applications Across Multiple MaterialsThis combination drill and tap set is ideal for a wide range of applications and materials:Automotive Repair: Threading holes for bolts, brackets, and componentsElectrical Work: Creating threaded holes for panels, boxes, and conduitMetalworking: Precision threading in steel, aluminum, brass, and copperSheet Metal: Drilling and tapping thin materials up to 10 gaugeFurniture Assembly: Creating clean, accurate threaded holes for hardwareDIY Projects: Any project requiring threaded fastenersWhat's Included1 x 6-32 NC Combination Drill and Tap Bit1 x 8-32 NC Combination Drill and Tap Bit1 x 10-32 NC Combination Drill and Tap Bit1 x 10-24 NC Combination Drill and Tap Bit1 x 12-24 NC Combination Drill and Tap Bit1 x 1/4-20 NC Combination Drill and Tap BitAll bits feature 1/4-inch quick-change hex shankQuality AssuranceEach bit is precision-ground and individually inspected to ensure sharpness, accuracy, and consistent performance.
