The bit features a titanium nitride (TiN) coating over an M35 cobalt steel body, extending tool life when drilling through abrasive and work-hardening materials. The 118-degree four-facet split point provides positive self-centering on entry and reduces thrust force during drilling. With a two-flute spiral design and web-thinned tapered web, chip evacuation is efficient even at small diameters. This is an OEM-grade precision bit conforming to DIN 338, intended for use by machinists, tool and die technicians, and maintenance professionals.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for production and maintenance drilling in metalworking applications. The TiN coating and M35 cobalt base material make it appropriate for aluminum, cast iron, mild steel, and stainless steel workpieces per the K, M, N, and P material group classifications. The straight-cylindrical shank seats securely in standard drill chucks and collet holders. With a maximum drilling depth of 12.40 mm and an overall length of 36.00 mm, this bit is designed for shallow, precise holes in small-diameter work such as tapping pilots, light fabrication, and instrument or electronic component assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM35 cobalt steel construction for heat and wear resistance in demanding alloys\u003c\/li\u003e\n  \u003cli\u003eTitanium nitride (TiN) coating reduces friction and extends cutting edge life\u003c\/li\u003e\n  \u003cli\u003e118-degree four-facet split point for self-centering entry without a center punch\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web reduces drilling torque and improves chip flow\u003c\/li\u003e\n  \u003cli\u003eDIN 338 standard geometry ensures dimensional consistency and interchangeability\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and collet holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement conforming to DIN 338 for use in standard drill chucks and collet holders accepting a 1.07 mm straight-cylindrical shank.

Ensure the machine spindle is fully stopped and locked out before changing tooling. At small diameters, run speed should be set appropriately to avoid bit deflection or breakage — consult a standard speeds-and-feeds reference for the specific workpiece material. Coolant through is not supported on this bit; flood coolant or cutting oil applied externally is recommended for ferrous materials.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: No. 58\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.0420 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Cobalt (M35)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Titanium Nitride (TiN)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Four Facet, Split\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1.07 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 22.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 14.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 36.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 12.40 mm (0.4880 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.000 to -0.014 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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 338\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 5519\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.002 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: 9055190010700\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51727164801330,"sku":"9055190010700","price":92.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bc2796606b86affad3ece68d198f005a.jpg?v=1788674219","url":"https:\/\/voomisupply.com\/products\/guhring-9055190010700-cobalt-jobber-drill-bit-no-58","provider":"Voomi Supply","version":"1.0","type":"link"}
