Built to DIN 6537 standards, this bit features a 140-degree split point (SU point type) with web thinning for self-centering entry and reduced thrust. The 0.4219-inch (27\/64) cutting diameter is paired with a coated finish that extends tool life in high-heat applications. At an overall length of 155 millimeters with a 7xD flute-to-diameter ratio, it is suited for moderate-depth holes where rigidity and chip evacuation both matter. Licensed HVAC technicians, machinists, and maintenance professionals working in metal fabrication and industrial service rely on this grade of tooling for consistent, repeatable results in production environments.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is engineered for use in brass, cast iron, hardened materials, nickel alloy, stainless steel, carbon steel, and titanium alloy. The coolant-through design channels cutting fluid directly to the tip, making it well-suited for CNC machining centers and powered column drills where coolant delivery is available. The straight shank fits standard collets and drill chucks without modification. With a maximum drilling depth of 3.54 inches (89.92 millimeters), it handles through-holes and blind holes in medium-thickness workpieces across Series 5512 tooling setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid submicron carbide construction for extended tool life in abrasive and hardened materials\u003c\/li\u003e\n  \u003cli\u003e140-degree SU split point with web thinning for self-centering, reduced-thrust entry\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design delivers fluid directly to the cutting edge for heat management\u003c\/li\u003e\n  \u003cli\u003eCoated finish resists wear and reduces built-up edge in sticky alloys such as stainless and nickel\u003c\/li\u003e\n  \u003cli\u003e7xD flute length-to-diameter ratio balances chip clearance with bit rigidity\u003c\/li\u003e\n  \u003cli\u003eStraight shank (0.4724-inch diameter) fits standard collets and chucks without adapters\u003c\/li\u003e\n  \u003cli\u003eManufactured to DIN 6537 standards with a diameter tolerance of +0.007 to +0.025 mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers, knee mills, and drill presses equipped with coolant-through capability.

Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Verify collet or chuck runout is within acceptable limits before drilling to avoid premature edge wear or bit breakage. When using the coolant-through feature, confirm that coolant pressure and flow rate are appropriate for the material and feed rate being used.\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: 27\/64 (0.4219 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\u003eTool Material\u003c\/strong\u003e: Solid Submicron Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight (Non-Threaded)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.4724 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.9292 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 106 millimeters\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length x Diameter Ratio\u003c\/strong\u003e: 7xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 155 millimeters\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 3.54 inches (89.92 millimeters)\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Brass, Cast Iron, Hardened Materials, Nickel Alloy, Stainless Steel, Steel, Titanium Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 5512\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 6537\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.4 pounds\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: 9055120107200\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51730722095410,"sku":"9055120107200","price":590.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9367e4b0405745015aebb06419a775ce.jpg?v=1788721764","url":"https:\/\/voomisupply.com\/products\/guhring-9055120107200-taper-length-drill-bit-0-4219-in","provider":"Voomi Supply","version":"1.0","type":"link"}
