Built from high speed steel with a coated finish, it features a 135-degree split point and web-thinned parallel web for reduced thrust and faster penetration on tough ferrous materials. At 25\/64 inch (0.3906 inches) in diameter, this bit runs a 1-7\/8-inch flute length within an overall length of 3-1\/4 inches. The stubby screw machine length body provides added rigidity compared to jobber-length drills, making it well suited for drill presses, CNC turret lathes, and screw machines where overhang must be minimized. Two right-hand spiral flutes clear chips efficiently under continuous-duty conditions.\u003c\/p\u003e\n\u003cp\u003eThis bit is intended for trade and industrial use in metalworking environments where consistent, repeatable hole quality is required. Primary workpiece materials are cast iron and steel. The straight-cylindrical shank fits standard drill chucks and collet holders without modification. Heavy-duty tool performance classification makes it appropriate for production shops, maintenance departments, and machine trades. The Series 2159 designation and NAS 907 specification confirm conformance to aerospace and industrial dimensional standards, supporting use in quality-controlled environments where traceability matters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e25\/64 inch diameter with tight tolerance of +0.0000 to -0.0010 inches for consistent hole sizing\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces walking and lowers thrust force on hard metals\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned parallel web construction improves chip flow and cutting efficiency\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length body maximizes rigidity and minimizes deflection\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel with coated finish for improved wear resistance in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eMeets NAS 907 and ISO standards for use in quality-controlled production settings\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and production drill bit for use in standard drill chucks and collet holders accepting straight-cylindrical shanks; rated for cast iron and steel workpiece materials per Series 2159 specification.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists, tool-and-die professionals, and maintenance technicians on drill presses, lathes, and CNC equipment. Ensure the machine spindle is fully stopped and locked out before inserting or removing the bit from the chuck or collet. Verify chuck or collet size matches the straight-cylindrical shank diameter before tightening. Follow shop safety protocols and applicable OSHA machine guarding requirements when operating drilling equipment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 25\/64 inch (0.3906 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: 3.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.875 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\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2159\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: NAS 907 (NAS), ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: 48225\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51729567744306,"sku":"48225","price":25.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7880d2543c20f0dde4053108fbc24dde.jpg?v=1788706237","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-48225-screw-machine-drill-bit-25-64-in","provider":"Voomi Supply","version":"1.0","type":"link"}
