Built to DIN 340 standards, it features a 130-degree standard point angle and a parabolic flute geometry that improves chip evacuation and reduces heat buildup during extended cuts. The bright, uncoated finish is standard for cobalt-grade tooling intended for use without coolant-through capability. A cylindrical shank with no threading keeps setup simple in conventional drill chucks. Licensed machinists, tool-and-die technicians, and precision metalworkers are the primary installers of this tooling.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for drilling cast iron, hardened materials, stainless steel, and steel. The 10xD flute-length-to-diameter ratio and overall length of 56.00 mm (2-13\/64 inches) make it appropriate for taper-length applications where extra reach beyond jobber-length drill bits is needed. It is typically applied in CNC machining centers, drill presses, and manual spindle operations where consistent hole geometry in ferrous and difficult-to-machine alloys is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt tool material for high-heat resistance in stainless steel and hardened materials\u003c\/li\u003e\n\u003cli\u003e130-degree standard point angle for positive cutting engagement on tough alloys\u003c\/li\u003e\n\u003cli\u003eParabolic flute design promotes efficient chip removal and reduces clogging\u003c\/li\u003e\n\u003cli\u003eDIN 340 taper length specification provides extended reach over standard jobber bits\u003c\/li\u003e\n\u003cli\u003eWeb-thinned parallel web construction reduces thrust and improves penetration\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with cylindrical shank for compatibility with standard drill chucks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a DIN 340-compliant taper length drill bit for use in standard cylindrical-shank toolholders and drill chucks accepting 0.0394 inch (1.00 mm) diameter shanks.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of precision drill bits of this diameter should be performed by qualified machinists or toolroom technicians familiar with small-diameter tooling. Secure the cylindrical shank fully in a properly sized collet or drill chuck before operation, and verify runout is within acceptable limits to prevent premature breakage at this diameter. Ensure spindle speed and feed rate are appropriate for the work material per established machining parameters. Do not apply side loading or use this bit as a reamer.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1.00 mm (0.0394 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 56.00 mm (2-13\/64 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 33.00 mm (1-19\/64 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 23.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 31.50 mm (1.2400 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Parabolic\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: Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0394 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length x Diameter Ratio\u003c\/strong\u003e: 10xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.000 to -0.014 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Cast Iron, Hardened Materials, Stainless Steel, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 336\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 340\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: GUHRING\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9003360010000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51742430036274,"sku":"9003360010000","price":48.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/88c0d959cb057282ae4bb1a3b6222fb0_cdfe81a3-3912-4858-b06c-b4f34fe0ceee.jpg?v=1788837411","url":"https:\/\/voomisupply.com\/products\/guhring-9003360010000-cobalt-taper-length-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
