Built to DIN 6537 standards, it features a 0.4291-inch (10.90 mm) cutting diameter, a 135-degree standard point angle, and a web-thinned tip geometry that reduces thrust and improves centering at entry. The two-flute regular spiral configuration evacuates chips efficiently, while the coated proprietary finish extends cutting edge life in demanding production environments. At 4.016 inches overall length, the stub-length body provides rigidity that minimizes deflection and runout during aggressive feeds.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for production machining, maintenance shops, and toolroom applications where a compact, rigid drill is needed for through-hole and blind-hole work. The straight cylindrical shank seats directly in standard drill chucks and collet holders without adapters. Coolant-through capability supports flood or high-pressure internal coolant delivery, making this bit appropriate for CNC machining centers and drill presses running continuous-cycle programs. The Series 142P designation places it within SGS high-performance solid carbide stub-length drills intended for universal material applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for high rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003e135-degree standard point angle with web-thinned geometry for reduced entry thrust\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports internal high-pressure coolant delivery\u003c\/li\u003e\n  \u003cli\u003eTwo-flute regular spiral configuration promotes efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eFour margins provide enhanced bore quality and hole straightness\u003c\/li\u003e\n  \u003cli\u003eDIN 6537 specification for consistent dimensional compliance\u003c\/li\u003e\n  \u003cli\u003eProprietary coating extends tool life across universal workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement for Series 142P screw machine length solid carbide drill bits with a 0.4291-inch cutting diameter and straight cylindrical shank; fits standard drill chucks and collet toolholders accepting an 11.999 mm shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the tool is secured with correct torque in a matching collet or chuck before initiating a cut. Verify coolant delivery lines are connected and flowing before engaging coolant-through operation. Do not exceed the rated maximum drilling depth of 2.165 inches per pass without retracting to clear chips.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.4291 inches (10.90 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.016 inches (101.999 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.165 inches (55.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.165 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.4724 inches (11.999 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.772 inches (45.001 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.089 inches (2.26 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Margins\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Treatment\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated Proprietary Finish\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.00024 to +0.00083 inches (+0.006 to +0.021 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 6537\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Universal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 142P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.28 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 4.14 inches length x 0.7 inches width x 0.7 inches height\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SGS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 66479\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51738405404978,"sku":"66479","price":380.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/40bbeb29e008228609ffd6575f2b34e8_f080f8bc-cbf3-4ed1-a2fd-120ec46db22b.jpg?v=1788799130","url":"https:\/\/voomisupply.com\/products\/sgs-66479-screw-machine-drill-bit-0-4291-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
