Built from high speed steel with a titanium nitride (TiN) coating, it delivers extended tool life in demanding production and maintenance environments. The 135-degree split point starts on contact without a center punch and reduces walking on hard surfaces. At 5-3\/8 inches overall length with a 3-15\/16-inch flute length, it fits standard drill chucks and magnetic drill setups. The web-thinned, tapered web construction reduces thrust load and improves chip evacuation. This bit is sold individually and suits machinists, pipefitters, ironworkers, and maintenance mechanics who need a reliable step-up from standard jobber bits.\u003c\/p\u003e\n\u003cp\u003eThe 41627 is rated for drilling cast iron, stainless steel, and carbon steel. Its Series 150ASP-TN designation places it in CHICAGO-LATROBE's high-performance jobber line, conforming to NAS 907 Type B standards. The straight-cylindrical shank seats securely in 3-jaw chucks and quick-change systems. The right-hand spiral flute pulls chips up and out of the hole, which is critical when drilling deeper holes in stainless or cast iron where heat buildup shortens tool life. It is well suited for fabrication shops, plant maintenance applications, and field service work where consistent hole tolerance is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point for self-centering start without a center punch\u003c\/li\u003e\n  \u003cli\u003eTiN coating increases surface hardness and reduces friction against hard metals\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web reduces thrust and improves chip flow\u003c\/li\u003e\n  \u003cli\u003eRight-hand, regular spiral flute design for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank for compatibility with standard 3-jaw chucks\u003c\/li\u003e\n  \u003cli\u003eMeets NAS 907 Type B specification for consistent dimensional tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for primary workpiece materials including cast iron, stainless steel, and steel.

Reduce spindle speed when drilling stainless steel or cast iron to manage heat — use cutting fluid where the machine setup allows. Inspect the cutting edge before each use; a TiN-coated bit that has been resharpened loses the coating benefit at the cutting edge. Follow shop safety protocols and wear appropriate eye protection during drilling operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 27\/64 inch (0.4200 inch)\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\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\u003eOverall Length\u003c\/strong\u003e: 5-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3-15\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1-7\/16 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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0010 to 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: NAS 907 Type B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 150ASP-TN\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: 0.9 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: 41627\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51738467139890,"sku":"41627","price":29.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/005b364a4c3293f90e0c0420d7935d49.jpg?v=1788799905","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-41627-jobber-drill-bit-27-64-in-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
