Built from high speed steel (HSS) with a coated finish, it features a 135-degree split point that reduces walking and requires less feed pressure at the start of the cut. The web-thinned, parallel web construction improves chip evacuation and reduces thrust load. At 0.234 inches in diameter with an overall length of 2.4375 inches, this short-length bit fits standard drill chucks and provides added rigidity compared to jobber-length tooling. A licensed HVAC tech, machinist, or metalworking professional will find this bit well-suited to production drilling applications.\u003c\/p\u003e\n\u003cp\u003eThe 48233 is built for drilling cast iron and steel in screw machine, turret lathe, and CNC drilling applications where stub-length rigidity matters. The straight-cylindrical shank seats cleanly in standard drill chucks and collet holders. Two spiral flutes in a regular helix clear chips efficiently during through-hole and blind-hole operations. It is produced to NAS 907 and ISO standards, making it appropriate for controlled manufacturing environments where dimensional consistency is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point reduces drill walking and lowers required feed pressure\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, parallel web construction reduces thrust and improves chip flow\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length provides greater rigidity than jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel with coated finish extends tool life in cast iron and steel\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, two-flute spiral design for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eMeets NAS 907 and ISO standards for dimensional and performance consistency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for drilling cast iron and steel.

Use appropriate cutting fluid or coolant for the workpiece material to maximize tool life, noting that this bit does not support internal coolant delivery. Follow applicable shop safety standards and machine guarding requirements when operating drilling equipment. Replace the bit if the cutting edges show visible wear or if hole diameter tolerance drifts outside acceptable limits.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.234 inches (15\/64 inch, Size A)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.4375 inches (2-7\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.3125 inches (1-5\/16 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\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular Helix\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\u003eWeb Configuration\u003c\/strong\u003e: Parallel, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\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\u003eTool Performance\u003c\/strong\u003e: Heavy-Duty\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: NAS 907, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2159\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: 48233\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51751270318386,"sku":"48233","price":15.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7baeb4cb4f3e699ca27502bf6d33d382.jpg?v=1788922563","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-48233-screw-machine-drill-bit-0-234-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
