At 0.1299 inches (3.30 mm) in diameter, it features a 140-degree split point angle with X-thinning for reduced thrust and improved self-centering at entry. The EgiAs coating provides enhanced lubricity and heat resistance, extending tool life in ferrous and non-ferrous materials. Coolant-through capability supports chip evacuation in deep-hole operations. This bit is built for CNC machining centers and production drilling environments where accuracy and tool longevity are critical.\u003c\/p\u003e\n\u003cp\u003eThe 653012912 is suited for production-floor and job-shop environments running tight-tolerance drilling in steel, stainless, aluminum, and similar workpiece materials. The 10xD flute-length-to-diameter ratio makes it well-suited for deeper hole depths without sacrificing rigidity. The straight shank at 4.00 mm (approximately 0.157 inches) fits standard collet chucks and toolholders common in CNC machining setups. It is typically installed and used by machinists and CNC operators working in precision manufacturing, aerospace, automotive, or general metalworking applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n  \u003cli\u003eEgiAs coating for improved heat resistance and extended tool life\u003c\/li\u003e\n  \u003cli\u003e140-degree point angle with X-thinning reduces entry thrust and improves centering\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports chip evacuation in deep-hole drilling\u003c\/li\u003e\n  \u003cli\u003e10xD flute-length-to-diameter ratio enables deeper hole penetration\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute cut for standard CNC and manual machine compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-specification taper length drill bit for use in collet chucks and toolholders accepting a 4.00 mm straight shank, compatible with CNC machining centers and drill presses configured for this shank size.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and tool changes should be performed by a qualified machinist with the machine fully powered down and locked out per applicable safety procedures. Ensure the straight shank is fully seated and the collet or toolholder is torqued to the machine manufacturer's specification. Verify coolant-through lines are clear and delivering adequate flow before running deep-hole cycles. Inspect the cutting edge for chips or wear before each use to prevent workpiece damage or tool breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.1299 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (mm)\u003c\/strong\u003e: 3.30 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: EgiAs\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 4.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 45.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length to Diameter Ratio\u003c\/strong\u003e: 10xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 100.00 mm (approximately 3.94 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: X-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 6530\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 pounds\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: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 653012912\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51749299650866,"sku":"653012912","price":279.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d31008abec274f4e968ff2dec495352b_06f7cd6b-489b-4251-8926-f5669986792b.jpg?v=1788904239","url":"https:\/\/voomisupply.com\/products\/osg-653012912-taper-length-drill-bit-0-1299-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
