Manufactured from high speed steel with an oxide coating for added lubricity and surface protection, it features a 118-degree standard point angle suited to a wide range of ferrous and non-ferrous materials. At 9.25 mm (0.3642 inches) in diameter and 127 mm (5 inches) overall length, this right-hand spiral-flute drill covers the most common range of through-hole and blind-hole applications encountered in trade and shop environments. Installation and use are handled by machinists, tool-and-die technicians, and maintenance mechanics.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for general-purpose use in drill presses, CNC machining centers, and hand-held power drills where a straight-cylindrical shank can be chucked directly. Its two-flute spiral geometry promotes efficient chip evacuation during through-hole drilling in mild steel, aluminum, brass, and similar materials. The oxide surface finish reduces friction at the cutting edge during moderate-speed operations without the need for specialized coolant delivery, as coolant-through is not supported on this design.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e9.25 mm (0.3642 inch) diameter covers the 9.00 to 10.00 mm size range\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle for general-purpose material entry\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction for durability across common workpiece materials\u003c\/li\u003e\n\u003cli\u003eOxide coating reduces friction and provides mild corrosion resistance\u003c\/li\u003e\n\u003cli\u003eRight-hand, two-flute spiral geometry for efficient chip clearing\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard three-jaw drill chucks directly\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber drill for use in standard three-jaw chucks accepting straight-cylindrical shanks across drill presses, CNC equipment, and portable power drills within the 9.00 to 10.00 mm drill size range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eSecure the straight-cylindrical shank fully in a properly sized chuck before operation and confirm the chuck key is removed before powering the spindle. Use appropriate cutting fluid or coolant for the workpiece material when drilling ferrous metals to extend tool life. Inspect the cutting edges for wear or chipping before each use and replace the bit if the point shows visible damage. Follow applicable shop safety standards and machine guarding requirements during all drilling operations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 9.25 mm (0.3642 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 127 mm (5 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 92 mm (3.62 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.12 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\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: C.402.0925\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51729005084978,"sku":"C.402.0925","price":15.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fa3122600367a7feb4d8fbc228d8b5a3.jpg?v=1788698717","url":"https:\/\/voomisupply.com\/products\/hertel-c-402-0925-jobber-drill-bit-9-25-mm-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
