Built from high speed steel with a titanium nitride (TiN) coating, it cuts wire gauge size 57, which equals 0.0430 inches in decimal. The 135-degree split point reduces walking on entry and works well on hard materials without a center punch. A web-thinned, tapered web design lowers thrust requirements and improves chip evacuation. Overall length is 1.75 inches with a 0.375-inch flute length. This bit is part of the Series 150ASP-TN and meets NAS 907 Type B standards. It is suited for machinists, pipefitters, and maintenance technicians who need consistent, repeatable hole quality in tight tolerances.\u003c\/p\u003e\n\u003cp\u003eThe 41727 is rated for use in cast iron, stainless steel, and steel. Its straight-cylindrical shank at 0.0430 inches diameter seats securely in standard drill chucks and collet holders. The right-hand spiral flute with regular spiral geometry suits production drilling and repair work alike. At 1.75 inches overall length, it fits compact drill presses, benchtop machines, and hand drills used in mechanical, HVAC, plumbing, and electrical trade work where small-diameter precision holes are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire gauge size 57 (0.0430 inches) with diameter tolerance of -0.0005 to 0.0000 inches for tight, repeatable hole sizing\u003c\/li\u003e\n  \u003cli\u003e135-degree standard point angle reduces drill walking and improves entry on hard metals\u003c\/li\u003e\n  \u003cli\u003eTitanium nitride (TiN) coating increases surface hardness and extends cutting life compared to uncoated HSS\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web lowers cutting thrust and clears chips more efficiently\u003c\/li\u003e\n  \u003cli\u003eRight-hand, regular spiral flute with 2-flute configuration suits general-purpose metal drilling\u003c\/li\u003e\n  \u003cli\u003eMeets NAS 907 Type B specification for consistent dimensional and performance standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for drilling cast iron, stainless steel, and carbon steel.

Secure the workpiece fully before drilling to prevent bit deflection at small diameters. Apply cutting fluid when drilling stainless steel or hardened steel to manage heat buildup and preserve coating life. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is observed.\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: 57\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0430 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\u003eOverall Length\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0430 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\u003eDrill Bit Material\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\u003ePoint Type\u003c\/strong\u003e: Standard\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\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0005 to 0.0000 inches\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: 41727\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51754489217330,"sku":"41727","price":60.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7eb7ffb1f4171cb8bc74415b7c7e5fc9.jpg?v=1788945933","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-41727-wire-size-57-hss-tin-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
