Upgrade your toolbox with the ARTU 3/16 in. x 5-1/2 in. L Tungsten Carbide Tipped Multi-Purpose Drill Bit. The combination of a tough tungsten carbide tip and a sturdy straight shank delivers durable performance and precise holes, even in demanding materials. If you’re tackling metalworking, fabrication, or tough projects, this bit is built to keep going where standard bits wear out.
Why this bit stands out
-
Tungsten carbide tipped for exceptional wear resistance and extended life when drilling hard metals such as steel and cast iron, with cleaner, more accurate holes over time.
-
Multi-purpose design engineered to handle a variety of workshop tasks, delivering reliable results on metal and other hard materials encountered in everyday projects.
-
Straight shank with a 1/8" shank diameter, compatible with a wide range of drill chucks for quick setup and universal use.
-
Precise dimensions—3/16" drill size, 3-1/4" flute length, and 5-1/2" overall length—optimizing chip clearance and control for longer, smoother drilling sessions.
-
Retail-ready packaging—carded, single-piece packaging from ARTU for easy storage, identification, and现场 display.
Ideal applications and use cases
- Drilling through harder metals in home workshops, fabrication shops, or automotive repairs where durability matters.
- Prep work on aluminum and other alloys that demand a steady, sharp edge to minimize wandering and improve hole quality.
- General-purpose metal fabrication tasks where a single bit needs to perform reliably across multiple projects.
Practical tips for best results
- Use a low to moderate drill speed when working with metals to reduce heat buildup and prolong edge life.
- Apply light lubrication or cutting fluid to improve chip evacuation and extend tool life on tough materials.
- Center-punch the workpiece to prevent bit walk, then gradually increase feed pressure as the bit engages the material.
- Let the bit do the work—avoid excessive force which can cause premature wear or breakage of the carbide tip.
In short, the ARTU 3/16 in. x 5-1/2 in. Tungsten Carbide Tipped Multi-Purpose Drill Bit with Straight Shank is designed for serious metalwork and robust DIY tasks. Its durable carbide tip, well-proportioned dimensions, and compatible straight shank deliver dependable performance hole after hole, making it a smart, long-term addition to any professional or enthusiast’s toolkit.
