Built to DIN 6537L standards, it features a 140-degree split-point (SU) geometry with web thinning for self-centering entry, reducing the need for a center punch on flat or curved surfaces. The cutting flutes are finished with FIREX coating, a multilayer physical vapor deposition finish that extends tool life and resists heat buildup in demanding production environments. With a 5xD flute-to-diameter ratio and through-coolant capability, this bit is suited for CNC machining centers and deep-hole drilling applications where chip evacuation and thermal management are critical. Licensed machinists, tool-and-die shops, and production machine operators are the primary users.\u003c\/p\u003e\u003cp\u003eThis drill bit is built for cutting cast iron and steel workpieces in both job-shop and production settings. The straight-cylindrical shank seats directly into standard drill chucks and collet holders without modification. Its regular spiral flute geometry maintains consistent chip flow at moderate to high spindle speeds. Applications include through-hole and blind-hole drilling in structural steel, ductile iron, and gray cast iron components typical of manufacturing, fabrication, and maintenance machining operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFIREX multilayer coating for extended tool life in ferrous materials\u003c\/li\u003e\n\u003cli\u003e140-degree SU split point with web thinning for self-centering, walk-free entry\u003c\/li\u003e\n\u003cli\u003eThrough-coolant capable for deep-hole drilling and heat management\u003c\/li\u003e\n\u003cli\u003eSubmicron solid carbide construction for rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003eDIN 6535 and DIN 6537L compliant straight-cylindrical shank\u003c\/li\u003e\n\u003cli\u003e2-flute regular spiral design optimized for cast iron and steel chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers and drill presses with standard straight-shank collet or chuck toolholding rated for the 0.4724-inch shank diameter.

Ensure the machine spindle and toolholder are fully de-energized and locked out before inserting or removing the bit. Confirm the collet or chuck bore matches the 0.4724-inch shank diameter before tightening. When running through-coolant, verify that the coolant supply pressure and flow rate are appropriate for the application before initiating the cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.4528 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.4724 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.6457 inches (118.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.7953 inches (71.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.1160 inches (53.75 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.8504 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: Regular Spiral\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\u003eMaterial\u003c\/strong\u003e: Submicron Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: FIREX\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\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 5xD\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\u003eDiameter Tolerance\u003c\/strong\u003e: 0.007 to 0.025 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 5511\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: DIN 6535, DIN 6537L\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Designation\u003c\/strong\u003e: DIN 6537L\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.28 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: 9055110115000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51728146137394,"sku":"9055110115000","price":417.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/05221ee3ce3b80244db5048b38866d2c_3efbcac3-3fc0-4f2a-9022-a702dbfc4e3a.jpg?v=1788688776","url":"https:\/\/voomisupply.com\/products\/guhring-9055110115000-carbide-drill-bit-0-4528-in","provider":"Voomi Supply","version":"1.0","type":"link"}
