Built to DIN 340 standards, this high-performance bit features an 11\/32-inch (0.3438 inch) diameter with a 130-degree split point and a parabolic flute geometry that promotes efficient chip evacuation and reduced thrust. The cylindrical shank fits standard drill chucks and milling machine spindles. Licensed HVAC, plumbing, and electrical contractors as well as machinists and maintenance trades rely on cobalt tooling like this when working through hardened fasteners, structural steel, stainless fixtures, and cast iron pump housings where high-speed steel bits fall short.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for drilling cast iron, hardened materials, stainless steel, and carbon steel in both shop and field environments. The 10xD flute-length-to-diameter ratio and parabolic flute design allow for deeper cuts with fewer peck cycles compared to standard jobber-length bits. The web-thinned, parallel web construction reduces the chisel edge load at entry, making it appropriate for hand-held drill motors, drill presses, and CNC machining centers where consistent hole quality is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt tool material rated for high-performance drilling in hardened and abrasion-resistant workpieces\u003c\/li\u003e\n  \u003cli\u003e130-degree standard point angle optimized for self-centering entry on flat and curved surfaces\u003c\/li\u003e\n  \u003cli\u003eParabolic flute geometry promotes fast chip removal and reduces heat buildup at depth\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned parallel web reduces drill entry force and chisel edge wear\u003c\/li\u003e\n  \u003cli\u003eDIN 340 taper length body provides extra reach compared to jobber-length bits at the same diameter\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, cylindrical shank fits standard 3-jaw chucks without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-matched replacement or direct addition for tooling setups requiring DIN 340 Series 336 taper length cobalt drill bits in 11\/32-inch diameter.

Always secure the workpiece and verify chuck runout before beginning a drilling operation. Power down and de-energize or lock out the drilling machine before changing bits. Do not exceed the recommended speed and feed parameters for cobalt tooling in the target material to avoid premature edge wear or bit breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Inch)\u003c\/strong\u003e: 11\/32\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.3438 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 4-17\/32 inches\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\u003ePoint Type\u003c\/strong\u003e: Standard\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: 11\/32 inches\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: 6-7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 4.012 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.000 to -0.022 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 340\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 336\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreaded Shank\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Cast Iron, Hardened Materials, Stainless Steel, Steel\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: GUHRING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9003360087300\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51728746676530,"sku":"9003360087300","price":109.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/88c0d959cb057282ae4bb1a3b6222fb0_c77db439-f6dc-428d-871b-01b680d0fa83.jpg?v=1788695763","url":"https:\/\/voomisupply.com\/products\/guhring-9003360087300-taper-length-drill-bit-0-3438-in","provider":"Voomi Supply","version":"1.0","type":"link"}
