Built from M7 high speed steel with a TiCN (Titanium Carbonitride) coating, this bit runs harder and longer between sharpenings than standard uncoated HSS tooling. The 135-degree notched split point starts on contact without a center punch, reducing walking on flat or curved surfaces. At 5 inches overall length with a 3-5\/8-inch flute, it fits standard drill chucks and drill presses used in fabrication, mechanical, plumbing rough-in, and HVAC sheet metal work.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for production and maintenance drilling in steel, cast iron, and similar ferrous workpiece materials. The parabolic flute geometry clears chips aggressively, making it effective in deeper holes where standard flutes pack and bind. The straight cylindrical shank at 3\/8 inch diameter seats securely in keyed or keyless chucks. Series 150WLPN is a heavy-duty general-purpose jobber series intended for shop, field, and service truck use by machinists, pipefitters, electricians, and HVAC technicians who drill metal regularly.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM7 high speed steel construction for heavy-duty service life in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eTiCN coating increases surface hardness and reduces friction for extended tool life\u003c\/li\u003e\n  \u003cli\u003e135-degree notched split point eliminates walking and reduces thrust force at start\u003c\/li\u003e\n  \u003cli\u003eParabolic flute design clears chips efficiently in deeper holes\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web reduces cutting resistance through the full depth\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, straight cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 3\/8-inch capacity or larger drill chucks on portable drills, drill presses, and milling machines.

Use appropriate cutting fluid or lubricant when drilling steel to extend bit life and maintain hole quality. Wear eye protection and secure the workpiece to prevent rotation. Inspect the cutting edges before each use and replace or resharpen 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 Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3-5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.3750 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: Notched Split Point\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Parabolic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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: M7 High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 150WLPN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.7 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: 42024\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51742574903602,"sku":"42024","price":43.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1a92f4b29ec156bd0e3202d23a71a3ce_0ae909e4-8060-406e-a617-15bc58da5fc1.jpg?v=1788838148","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-42024-3-8-inch-jobber-drill-bit-ticn-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
