It features a 140-degree SU point angle with web thinning for self-centering entry and reduced thrust. The 4.20 mm (0.1654 inch) diameter cutting edge is ground with a spiral flute in a right-hand cutting direction. A 6.00 mm straight shank and 7xD flute-to-diameter ratio make this bit suited for deep-hole work in difficult-to-machine alloys. Coolant-through capability supports chip evacuation and heat management at depth. Licensed machinists, tool-and-die shops, and production drilling operations are the primary users of this tooling.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is built for production and precision drilling into hard and abrasive workpiece materials including stainless steel, hardened materials, nickel alloy, titanium alloy, cast iron, brass, and steel. The Series 5512 design conforms to DIN 6537 standards, making it compatible with standard toolholding setups that accept straight-shank tooling in the 6.00 mm shank diameter range. It is appropriate for CNC machining centers and manual drilling operations where coolant-through toolholding is available. The coated submicron carbide grade extends tool life in interrupted cuts and abrasive stock.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid submicron carbide construction for high wear resistance in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003e140-degree SU point with web thinning for self-centering entry and reduced axial load\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports internal chip flushing and heat management at full drilling depth\u003c\/li\u003e\n  \u003cli\u003e7xD flute-to-diameter ratio allows drilling to a maximum depth of 31.20 mm (1.228 inches)\u003c\/li\u003e\n  \u003cli\u003eCoated finish improves lubricity and extends tool life in stainless steel, nickel alloy, and titanium applications\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 6537 for dimensional consistency and toolholder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style taper length drill bit for use in standard straight-shank toolholders accepting a 6.00 mm shank diameter.

Secure the straight shank fully in a collet or drill chuck rated for the 6.00 mm shank diameter before use. Confirm that the coolant-through supply is active before engaging the workpiece to prevent premature carbide failure from thermal shock. Inspect the cutting edge for chipping before each use, as solid carbide is brittle and sensitive to side-loading or interrupted entry without proper setup.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 4.20 mm (0.1654 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\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\u003c\/strong\u003e: Coated\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\u003eFlute Length\u003c\/strong\u003e: 37.50 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length to Diameter Ratio\u003c\/strong\u003e: 7xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 31.20 mm (1.228 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 75.00 mm\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: 6.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 36.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.004 to +0.016 mm\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\u003eTool Application\u003c\/strong\u003e: Self-Centering\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\u003eDrill Bit Grade\u003c\/strong\u003e: High Performance\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: 9055120042000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51730668978482,"sku":"9055120042000","price":313.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dcdfadd2296fea2710883e16c9cb0052_b50e713a-3e76-4453-bc03-ea067378d2ff.jpg?v=1788721181","url":"https:\/\/voomisupply.com\/products\/guhring-9055120042000-taper-length-drill-bit-0-1654-in","provider":"Voomi Supply","version":"1.0","type":"link"}
