It features a 13.1 mm diameter, a 140-degree split-point (SU) tip, and a FIREX coating that extends tool life under demanding conditions. The web-thinned, tapered web design reduces thrust and promotes self-centering entry without a pilot hole. With a 5xD flute-to-diameter ratio and coolant-through capability, this drill is built for production environments where precision and cycle time both matter. Machinists and tool-room professionals working with CNC machining centers are the primary users.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for drilling cast iron and steel in both job-shop and production settings. Its straight-cylindrical shank seats securely in standard drill chucks and hydraulic tool holders. The regular spiral flute and right-hand cut make it compatible with conventional CNC machining center spindles. The coolant-through design supports high-pressure coolant delivery directly to the cutting zone, making it practical for deeper holes and harder materials where chip evacuation is critical. It conforms to DIN 6537 L and DIN 6535 standards, which are common references in precision metalworking specifications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide submicron-grade construction for rigidity and wear resistance in steel and cast iron\u003c\/li\u003e\n\u003cli\u003eFIREX coating provides thermal protection and extended tool life in ferrous materials\u003c\/li\u003e\n\u003cli\u003e140-degree SU split-point geometry is self-centering, reducing the need for center drilling\u003c\/li\u003e\n\u003cli\u003eCoolant-through design channels high-pressure coolant to the cutting edge for chip evacuation and heat control\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web reduces drilling thrust and improves penetration efficiency\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 6537 L and DIN 6535 standards for consistent dimensional and geometric tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in cast iron and steel workpiece materials, conforming to DIN material codes K and P.

Seat the straight-cylindrical shank fully in a clean, undamaged chuck or hydraulic holder to the specified shank engagement length before tightening. Verify coolant-through passages are clear and coolant pressure is set per machine and job specifications before starting the cut. Inspect the cutting edges and coating condition before each use — chipped or worn edges in carbide tooling should be replaced, not reground, without proper carbide grinding equipment.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 13.1 mm (0.5157 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 124 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 77 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 14 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 45 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 70 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: SU (Self-Centering)\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, Regular\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\u003eCoating\/Finish\u003c\/strong\u003e: FIREX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide, Submicron Grade\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: 0.007 to 0.025 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Cast Iron, Steel (DIN codes K and P)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: DIN 6537 L, DIN 6535\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 5511\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.4 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: 9055110131000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51753742598450,"sku":"9055110131000","price":722.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/05221ee3ce3b80244db5048b38866d2c_7a9ad74a-bab9-4726-8bcf-534dfcb58918.jpg?v=1788940212","url":"https:\/\/voomisupply.com\/products\/guhring-9055110131000-carbide-jobber-drill-bit-13-1mm","provider":"Voomi Supply","version":"1.0","type":"link"}
