It measures 0.189 inches in diameter (Wire Size 12) with an overall length of 2.25 inches and a flute length of 1.1875 inches. The bit is manufactured from high speed steel with a coated finish and features a 135-degree split point for fast penetration and reduced walking on entry. The shortened screw machine length body provides added rigidity in drill press, turret lathe, and screw machine applications where stub-length tools are required. Licensed trades and machining shops are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for production drilling operations in residential and commercial fabrication, mechanical contracting, and maintenance environments. Its heavy-duty grade and web-thinned parallel web construction make it appropriate for repetitive through-hole and blind-hole work in ferrous metals including cast iron and steel. The right-hand spiral flute geometry clears chips efficiently in these materials. Series 159 is a recognized production-grade line built to NAS 907 and ISO standards, making it a common choice for shops that specify controlled-tolerance tooling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point reduces thrust and prevents bit walking on entry\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned parallel web improves chip evacuation in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eScrew machine length body increases rigidity over jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with coated finish for extended service life\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance held to +0.0000 to -0.0007 inches for consistent hole sizing\u003c\/li\u003e\n  \u003cli\u003eBuilt to NAS 907 and ISO standards for production and controlled-tolerance applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for drilling cast iron and steel in screw machine, turret lathe, and drill press setups where a stub-length, straight-cylindrical shank bit is required.

Use cutting fluid appropriate for the workpiece material when drilling steel or cast iron to manage heat and extend bit life. Do not exceed the rated speed range for the bit diameter in the applicable machinery manual. Inspect the cutting edges and coating before each use and replace the bit 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: 0.189 inches (Wire Size 12)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute 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\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\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating \/ Finish\u003c\/strong\u003e: Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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: Parallel, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0007 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 159\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: NAS 907, ISO\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: 0.0143 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: 49382\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51754532208946,"sku":"49382","price":44.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7e6259b41b4a881e982c2a2538ad83d2.jpg?v=1788946364","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-49382-screw-machine-drill-bit-0-189-in","provider":"Voomi Supply","version":"1.0","type":"link"}
