Built from high speed steel with a titanium nitride (TiN) coating, this bit delivers extended tool life and reduced heat buildup in demanding applications. The 135-degree split point geometry starts on contact without center-punching and cuts aggressively through cast iron, stainless steel, and structural steel. Overall length is 6 inches with a 4.5-inch flute length. The straight-cylindrical shank measures 1.5 inches in length and is sized to fit standard drill chucks. Web-thinned construction reduces thrust load during entry, making it well suited for high-cycle production or field drilling work.\u003c\/p\u003e\u003cp\u003eThe 41632 is intended for trade and industrial use where standard jobber-length bits come up short on performance. It fits residential and commercial construction, fabrication shops, mechanical contractors, and maintenance operations that regularly drill cast iron, stainless, or mild steel. The regular spiral flute provides reliable chip evacuation in through-hole drilling. Right-hand cut direction is standard for conventional drill press and handheld drill operation. This bit conforms to NAS 907 Type B standards, making it appropriate for controlled manufacturing environments as well as general mechanical work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTiN coating extends cutting life and reduces friction on hard ferrous materials\u003c\/li\u003e\n\u003cli\u003e135-degree split point starts on contact, eliminating the need for a center punch on flat stock\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web reduces axial thrust and improves penetration rate\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction handles cast iron, stainless steel, and carbon steel\u003c\/li\u003e\n\u003cli\u003eRight-hand, regular spiral flute promotes consistent chip clearing in through-hole applications\u003c\/li\u003e\n\u003cli\u003eMeets NAS 907 Type B standard for dimensional and performance consistency\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a jobber-length replacement drill bit compatible with standard straight-shank drill chucks used in drill presses, magnetic drills, and handheld electric drills.

Secure the shank fully in the chuck and verify chuck key is removed before starting. Apply cutting fluid or coolant when drilling stainless steel or cast iron to manage heat and extend bit life. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is present.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\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\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\u003eWeight\u003c\/strong\u003e: 1.4 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 41632\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51728609444146,"sku":"41632","price":34.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/22b3a3087233a417f3e47e595a40488b.jpg?v=1788693921","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-41632-1-2-in-hss-tin-jobber-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
