It features a 135-degree split point for reduced walking and faster penetration on hard materials. The web-thinned, tapered web design lowers thrust requirements and improves chip evacuation. At 3.625 inches overall length with a 2.4375-inch flute length, this bit fits standard drill chucks and handles demanding production or maintenance drilling tasks. It is intended for use by machinists, maintenance technicians, and metalworking tradespeople requiring a heavy-duty, high-performance drill bit that meets NAS 907 Type B standards.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for drilling cast iron, stainless steel, and carbon steel in residential, commercial, and industrial maintenance applications. The TiN coating extends tool life by reducing friction and heat buildup at the cutting edge, making it a practical choice for repeat-use scenarios in metal fabrication shops, mechanical rooms, and field service environments. The straight-cylindrical shank seats securely in keyed or keyless chucks across a wide range of portable and bench-mounted drill equipment. Series 150ASP-TN designates the heavy-duty performance tier within the CHICAGO-LATROBE line.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire size 7 diameter: 0.2010 inches, conforming to NAS 907 Type B specification\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces bit walking and decreases required feed pressure\u003c\/li\u003e\n  \u003cli\u003eTitanium nitride (TiN) coating increases surface hardness and extends tool life\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web improves chip flow and lowers cutting thrust\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute with regular helix for consistent chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank sized at 1.1875 inches for secure chuck engagement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use jobber drill bit for metalworking applications requiring a wire gauge size 7 drill in high-speed steel; compatible with standard drill chucks accepting a straight-cylindrical shank.

Secure the straight-cylindrical shank firmly in the chuck and verify runout before beginning the cut. Always wear appropriate eye protection and secure the workpiece before drilling. Cutting fluid or coolant is recommended when drilling stainless steel or hardened steel to manage heat, even though this bit does not have an internal coolant-through channel.\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: 7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.2010 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.4375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1.1875 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\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\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Stainless Steel, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0007 to 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\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: 0.3 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: 41677\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51747264987442,"sku":"41677","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6dc304dc974027c3b33ae33e8104160d.jpg?v=1788878364","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-41677-jobber-drill-bit-wire-7-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
