It features a 9.30 mm (0.3661 inch) diameter, a 118-degree standard point angle, and a black oxide coating that provides basic lubricity and corrosion resistance during use. The straight-cylindrical shank seats directly in standard drill chucks without adapters. With a two-flute spiral configuration and right-hand cutting direction, the bit evacuates chips efficiently during through-hole and blind-hole operations. Machinists, maintenance technicians, and fabricators reach for this size regularly in production and job-site settings.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for general-purpose drilling applications in light manufacturing, maintenance and repair, and fabrication shops. The 9.30 mm diameter falls within the 9.00 to 10.00 mm size range and is commonly used where a close metric size is required. The 127 mm overall length and 92 mm flute length are proportioned for stable, accurate drilling in standard drill presses, CNC machining centers, and hand-held power drills with compatible chucks. No coolant-through capability is present, so external cutting fluid or dry cutting is the standard approach.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e9.30 mm (0.3661 inch) diameter for precise metric-specification hole sizing\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle for general-purpose entry on a wide range of materials\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction provides adequate heat resistance for typical drilling speeds\u003c\/li\u003e\n\u003cli\u003eBlack oxide coating reduces friction and offers light corrosion resistance\u003c\/li\u003e\n\u003cli\u003eTwo-flute spiral geometry promotes efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard three-jaw drill chucks without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber drill compatible with any standard drill chuck accepting a straight-cylindrical shank in the 9.30 mm diameter range, including bench drill presses, CNC machining centers, and portable power drills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eSecure the shank fully in the drill chuck and verify concentricity before starting a cut. Power down and de-energize the machine before changing bits. Use appropriate cutting fluid or follow dry-drilling recommendations based on the workpiece material. Inspect the cutting edges for wear before each use and replace the bit when point geometry is degraded to avoid oversized or out-of-round holes.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 9.30 mm (0.3661 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 127 mm (5.00 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\/Finish\u003c\/strong\u003e: Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\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\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.402.0930\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51744811417906,"sku":"C.402.0930","price":19.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bae80283b5a3c40819f32e4a7dfcb639.jpg?v=1788860790","url":"https:\/\/voomisupply.com\/products\/hertel-c-402-0930-jobber-drill-9-30mm-hss-oxide","provider":"Voomi Supply","version":"1.0","type":"link"}
