It measures 15\/32 inches (0.4688 inches) in diameter and carries a 135-degree split-point tip that self-centers on contact, reducing the need for a center punch on most metals. The two-flute spiral design in the 150ASP-TN series is rated heavy duty and built to NAS 907 Type B standards. Licensed HVAC techs, machinists, pipefitters, and sheet metal workers reach for this bit when drilling through cast iron, stainless steel, and carbon steel in production and field settings.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for drilling cast iron, stainless steel, and mild steel in both shop and field conditions. Its jobber length makes it a direct fit in standard drill chucks and magnetic drill press setups. The straight-cylindrical shank accepts standard three-jaw chucks without an adapter. Typical applications include drilling pilot holes for pipe hangers, tapping clearance holes in steel framing, and general-purpose metal fabrication tasks that demand a durable, consistently sized hole.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point self-centers on metal surfaces and reduces walking at hole entry\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 reduces thrust load and improves chip clearance\u003c\/li\u003e\n  \u003cli\u003eRight-hand, regular spiral flute evacuates chips efficiently in deep-hole drilling\u003c\/li\u003e\n  \u003cli\u003eMeets NAS 907 Type B specification for dimensional and performance consistency\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard three-jaw drill chucks without modification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard drill presses, hand drills, and magnetic base drills equipped with a chuck accepting a straight-cylindrical shank at 15\/32-inch diameter.

Secure the bit fully in the chuck and verify runout before beginning a cut. Apply cutting fluid or a suitable metalworking lubricant when drilling stainless steel or cast iron to manage heat and extend bit life. Inspect the cutting edges for wear or chipping after heavy use and replace the bit if the point shows visible damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 15\/32 inches (0.4688 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 4-5\/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 Length\u003c\/strong\u003e: 1.4400 inches (36.51 mm)\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 Point\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\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\u003eCoating\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\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\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0010 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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.1 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: 41630\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51732788085042,"sku":"41630","price":32.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/af3aa2225bb717f84c69c490e2d02f18.jpg?v=1788746817","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-41630-jobber-drill-bit-15-32-in-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
