It features a 21\/32 inch cutting diameter paired with a 1\/2 inch straight-cylindrical shank, allowing it to be chucked in standard 1\/2 inch drill chucks without requiring a larger chuck size. The bit is manufactured from high-speed steel with an oxide finish, providing basic surface protection against corrosion and heat buildup. With a standard 118-degree point angle and right-hand spiral flute design, it delivers reliable chip evacuation during through-hole and blind-hole operations. Licensed HVAC, plumbing, and electrical tradespeople as well as general metalworkers will find this bit suitable for common production and maintenance drilling tasks.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for use on low and medium tensile strength workpiece materials such as mild steel, aluminum, brass, and similar metals. The 3 inch flute length supports a maximum drilling depth of 3 inches, covering most standard trade applications. The 6 inch overall length provides clearance in confined spaces or when working through fixture setups. The reduced shank design specifically addresses situations where the required hole size exceeds the available chuck capacity, making it a practical choice for field and shop use alike.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e21\/32 inch cutting diameter with a reduced 1\/2 inch straight-cylindrical shank for compatibility with standard 1\/2 inch chucks\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction suitable for drilling low and medium tensile strength metals\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with right-hand spiral flute for consistent chip removal\u003c\/li\u003e\n\u003cli\u003eOxide finish provides basic corrosion and heat resistance\u003c\/li\u003e\n\u003cli\u003e3 inch flute length with 6 inch overall length supports drilling up to 3 inches deep\u003c\/li\u003e\n\u003cli\u003eNo coolant required for general-purpose applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose reduced shank drill bit for use in any 1\/2 inch keyed or keyless drill chuck; suitable for drill presses, hand drills, and magnetic base drills accepting straight-cylindrical shanks.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit should be installed by a qualified tradesperson familiar with proper drilling practices. Secure the shank firmly in a 1\/2 inch chuck and verify runout before beginning a cut. Ensure the workpiece is clamped or fixtured to prevent rotation during drilling. Follow applicable shop safety and tool manufacturer guidelines when selecting feed rate and speed for the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 21\/32 inches (0.6562 inches decimal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Low and Medium Tensile Strength Materials\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Required\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.36 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241635\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 02387728\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51734758687026,"sku":"02387728","price":42.9,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5f8990c7a302c4a25f8ed6f266e92dde.jpg?v=1788766674","url":"https:\/\/voomisupply.com\/products\/hertel-02387728-reduced-shank-drill-bit-21-32-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
