It carries a FIREX coating for extended wear resistance and runs a right-hand spiral flute in a regular spiral configuration. The overall length is 4.055 inches (103 mm) with a flute length of 2.402 inches (61 mm) and a maximum drilling depth of 1.917 inches (48.70 mm). The straight-cylindrical shank measures 0.3937 inches in diameter. Built to DIN 6537L and DIN 6535 standards from submicron-grade carbide, this bit is suited for production drilling in cast iron and steel by machining professionals.\u003c\/p\u003e\u003cp\u003eThis drill bit is engineered for high-performance drilling in cast iron and steel workpieces, making it appropriate for production machining, tool and die, and precision fabrication environments. The self-centering SU point reduces the need for center-punching and improves positional accuracy in CNC and manual drilling operations. Coolant-through capability supports high feed rates and extended tool life in deep-hole and interrupted-cut applications. The 5xD flute-to-diameter ratio and web-thinned, tapered web construction help with chip evacuation in tighter tolerance bores.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid submicron-grade carbide construction for high rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eFIREX coating reduces heat buildup and extends service life in ferrous materials\u003c\/li\u003e\n\u003cli\u003e140-degree SU self-centering point improves hole location accuracy without a center punch\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports high feed rates and assists chip removal in deep holes\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web reduces thrust force and improves cutting efficiency\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 6537L and DIN 6535 standards for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for drilling cast iron and steel workpieces; primary workpiece material codes K and P per the input specifications.

Ensure the machine spindle and collet or chuck are clean and properly torqued before seating the shank. Carbide is brittle — avoid side loading, interrupted cuts without appropriate feeds, or dropping the tool on hard surfaces. When activating coolant-through function, verify the spindle coolant supply pressure and flow rate are within the machine specification before running.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 8.20 mm \/ 0.3228 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\u003eDrill Bit Material\u003c\/strong\u003e: Solid Carbide (Submicron Grade)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Finish \/ Coating\u003c\/strong\u003e: FIREX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral (Regular)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.402 inches (61.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.055 inches (103.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.917 inches (48.70 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3937 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.654 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: 0.006 to 0.021 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 5xD\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: DIN 6535, DIN 6537L\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 5511\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.16 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: 9055110082000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51748680532274,"sku":"9055110082000","price":308.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/05221ee3ce3b80244db5048b38866d2c_49f5908d-ecb8-448a-8933-8679cc058003.jpg?v=1788896606","url":"https:\/\/voomisupply.com\/products\/guhring-9055110082000-carbide-jobber-drill-bit-letter-p","provider":"Voomi Supply","version":"1.0","type":"link"}
