Built to DIN 6537L standards, this 12 mm (0.4724 inch) diameter bit features a 140-degree split point (SU geometry) for self-centering entry and reduced thrust. The submicron carbide substrate is finished with a Titanium Nitride (TiN) coating that improves surface hardness and extends tool life in production environments. With a web-thinned, tapered web design and two spiral flutes, it delivers efficient chip evacuation and consistent hole quality. Coolant-through capability makes it well suited for deep-hole applications at maximum drilling depths up to 53 mm.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for use in ferrous materials including cast iron and steel, corresponding to DIN material groups K and P. The 5xD flute-to-diameter ratio supports drilling depths up to 53 mm (2.087 inches) without step drilling. The whistle notch shank seats securely in compatible toolholders per DIN 6535, and the right-hand spiral flute geometry is compatible with conventional CNC machining centers, drill presses, and manual machine tools used in metal fabrication, maintenance, and production machining applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid submicron carbide construction for high wear resistance in ferrous materials\u003c\/li\u003e\n\u003cli\u003e140-degree SU split point provides self-centering entry and reduces walking on hard surfaces\u003c\/li\u003e\n\u003cli\u003eTiN coating increases surface hardness and prolongs cutting edge life\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports deep-hole drilling and heat management at the cutting zone\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web reduces axial thrust and improves chip flow\u003c\/li\u003e\n\u003cli\u003eWhistle notch shank (DIN 6535) ensures positive drive and minimal slippage in toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use tooling for machining setups requiring a DIN 6537L jobber-length solid carbide drill in the 10 mm to 12.5 mm diameter range.

Confirm spindle speed and feed rate are appropriate for solid carbide tooling in the target workpiece material before engaging the cut. Do not run carbide tooling in interrupted cuts or unstable setups without appropriate rigidity. When enabling coolant-through operation, verify coolant pressure and flow are within machine specifications before starting the cycle.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 12 mm (0.4724 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 118 mm (4.646 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 71 mm (2.795 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 53 mm (2.087 inches)\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: Whistle Notch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.4724 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide (Submicron Grade)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Titanium Nitride (TiN)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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 Material\u003c\/strong\u003e: Cast Iron, Steel (DIN Groups K and P)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 6537L, DIN 6535\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1183\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 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: 9011830120000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51738693140786,"sku":"9011830120000","price":492.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cbae5699708142d77b5e5800ead3b3d6_eb4cf76e-0439-4961-92ed-6d57d31f61d9.jpg?v=1788802940","url":"https:\/\/voomisupply.com\/products\/guhring-9011830120000-carbide-drill-bit-12-mm-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
