Built from high speed steel (HSS) with a coated finish, it delivers consistent performance in demanding shop and field applications. The 135-degree split point reduces walking and requires no center punch on flat surfaces. A web-thinned, parallel web configuration improves chip evacuation and reduces thrust during penetration. At 23\/64 inch (0.3594 inches) in diameter, with a total length of 3-1\/16 inches and a flute length of 1-3\/4 inches, this bit fits standard drill chucks and is suited for machinists, pipefitters, and fabricators working on structural steel and cast iron components.\u003c\/p\u003e\n\u003cp\u003eThe 48223 is configured for screw machine length work, meaning a shorter overall body than jobber-length bits for added rigidity in tight spaces or machine tool applications. The straight-cylindrical shank seats securely in drill press chucks, CNC turrets, and hand-held power drills. Primary workpiece materials are cast iron and steel, making this bit a practical choice for HVAC bracket fabrication, pipe hanger installation, electrical panel knockouts, and general metal fab work. The right-hand spiral flute design clears chips upward and away from the cut zone during continuous operation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point reduces walking and eliminates need for center punch on flat stock\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned parallel web lowers drilling thrust and improves chip flow\u003c\/li\u003e\n  \u003cli\u003eScrew machine length body provides added rigidity over jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with coated finish for extended tool life in steel and cast iron\u003c\/li\u003e\n  \u003cli\u003eRight-hand, 2-flute regular spiral design compatible with standard drill chucks and CNC turrets\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance held to +0.0000 to -0.0010 inches for precise hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in cast iron and steel workpieces.

Secure the workpiece firmly before drilling and ensure the drill chuck is fully tightened on the straight-cylindrical shank. Use cutting fluid or coolant when drilling through hardened steel to preserve bit life, noting this bit does not include a coolant-through channel. Follow applicable shop safety protocols and wear appropriate eye protection during operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 23\/64 inch (0.3594 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\u003eOverall Length\u003c\/strong\u003e: 3-1\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel, Web-Thinned\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\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Steel\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 Performance\u003c\/strong\u003e: Heavy-Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0010 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: 2159\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Number\u003c\/strong\u003e: NAS 907\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Designation\u003c\/strong\u003e: NAS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.4 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: 48223\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51727275491634,"sku":"48223","price":22.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a48fb89085b4394779f1520fd034b645.jpg?v=1788675774","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-48223-screw-machine-drill-bit-23-64-in","provider":"Voomi Supply","version":"1.0","type":"link"}
