It is made from high speed steel with a titanium nitride (TiN) coating that extends cutting life and reduces friction at the cutting edge. The No. 15 wire size corresponds to a decimal diameter of 0.1800 inches. The 135-degree split point reduces walking on contact and requires no center punch on flat surfaces. Overall length is 3-3\/8 inches with a 2-3\/16-inch flute length. This bit is suited for production and maintenance drilling in metalworking environments and is installed by machinists, maintenance technicians, and industrial tradespeople.\u003c\/p\u003e\n\u003cp\u003eThe 41685 is rated for use in cast iron, stainless steel, and steel. The right-hand spiral flute with regular helix evacuates chips efficiently during through-hole and blind-hole drilling. The straight cylindrical shank with a diameter of 1-3\/16 inches fits standard drill chucks on both corded and battery-powered drills as well as drill presses and CNC equipment. The tapered web configuration with web thinning reduces thrust and improves penetration in harder alloys. This bit is part of the CHICAGO-LATROBE 150ASP-TN series, which is built to NAS 907 Type B standards for high-performance tooling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHigh speed steel construction with titanium nitride coating for extended tool life\u003c\/li\u003e\n  \u003cli\u003e135-degree split point eliminates center-punch requirement and reduces bit walking\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web reduces drilling thrust in hard metals\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute with regular helix promotes efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank fits standard drill chucks and CNC toolholders\u003c\/li\u003e\n  \u003cli\u003eMeets NAS 907 Type B specification for high-performance heavy-duty drilling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for drilling cast iron, stainless steel, and steel workpieces.

Apply appropriate cutting fluid when drilling stainless steel or hardened alloys to manage heat and extend bit life. Always wear appropriate eye protection and secure the workpiece before drilling. Inspect the cutting edges for wear or chipping after extended use and replace the bit if diameter tolerance or point geometry is compromised.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 15\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1800 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2-3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1-3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.1875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular Helix\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: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Titanium Nitride (TiN)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0007 to 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Stainless Steel, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 150ASP-TN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: NAS 907 Type B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: CHICAGO-LATROBE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 41685\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51744817676594,"sku":"41685","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6d96f3b55b87f40ad03b580c3683e971.jpg?v=1788860911","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-41685-no-15-hss-tin-drill-bit-135-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
