Built to DIN 6537K specification, it features a 140-degree split point (SU type) with web thinning for reduced thrust and cleaner entry. The FIREX coating provides heat and wear resistance for extended tool life in abrasive and hard materials. At 0.3898 inches in diameter with a straight-cylindrical shank, this bit is suited for machinists, tool-and-die tradespeople, and precision drilling operations where dimensional accuracy and finish quality are critical.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is engineered for use across a wide range of workpiece materials including brass, cast iron, hardened materials, nickel alloy, stainless steel, carbon steel, and titanium alloy. Its 3xD flute-to-diameter ratio and regular spiral flute geometry make it appropriate for short-hole drilling in screw machine, CNC, and production drilling setups where tool rigidity and chip evacuation are priorities. Coolant-through capability is not supported on this model.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction with submicron-grade material for hardness and wear resistance\u003c\/li\u003e\n  \u003cli\u003eFIREX coating for elevated heat resistance and longer tool life in tough alloys\u003c\/li\u003e\n  \u003cli\u003e140-degree SU split point with web thinning for low thrust and accurate entry\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and collet systems\u003c\/li\u003e\n  \u003cli\u003eRegular spiral flute geometry supports efficient chip evacuation in short-hole applications\u003c\/li\u003e\n  \u003cli\u003eDIN 6537K specification ensures dimensional conformance for precision work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in screw machine, CNC, and production drilling operations targeting workpiece materials including brass, cast iron, hardened materials, nickel alloy, stainless steel, steel, and titanium alloy.

Secure the straight-cylindrical shank firmly in an appropriate chuck or collet before operation to prevent runout. Carbide tooling is brittle — avoid side loads, interrupted cuts without proper setup, and dropping or impact that can cause micro-fractures. Follow machine manufacturer feed and speed guidelines for the specific workpiece material being drilled.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.3898 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 (Split Point)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide (Submicron Grade)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: FIREX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 47.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 89.00 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 Length\u003c\/strong\u003e: 1.6535 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel (Web-Thinned)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 3xD\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\u003eDrill Bit Size Range\u003c\/strong\u003e: 0.3500 to 0.4000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 6537K\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 5514\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: 9055140099000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51730118738226,"sku":"9055140099000","price":216.16,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c99c65cd650f487cd7880d23a6e64e84.jpg?v=1788712012","url":"https:\/\/voomisupply.com\/products\/guhring-9055140099000-carbide-drill-bit-0-3898-in","provider":"Voomi Supply","version":"1.0","type":"link"}
