It is built from high speed steel with a coated finish for added wear resistance. The bit features a 135-degree split point with web thinning, which reduces walking and lowers thrust requirements at entry. At 1-3\/4 inches overall length with a 3\/4-inch flute length, this stub-length geometry increases rigidity and minimizes deflection in short-hole applications. It carries a straight-cylindrical shank and a two-flute spiral configuration. Diameter tolerance is held to +0.0000 to -0.0005 inches. This bit is used by machinists, pipefitters, and mechanical contractors working with metal fabrication and equipment assembly.\u003c\/p\u003e\u003cp\u003eThe 48412 is suited for screw machine operations, CNC drilling, and general-purpose bench drilling where a short, rigid bit is required. Primary workpiece materials are cast iron and steel. The stub-length design is common in production environments where hole depth is shallow and cycle time matters. Conformance to NAS 907 and ISO standards makes it appropriate for applications with documented quality requirements. It is sold individually with a minimum order quantity of 12 units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e135-degree split point with web thinning reduces thrust and prevents bit walking on entry\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with coated finish for improved wear life in ferrous materials\u003c\/li\u003e\n\u003cli\u003eScrew machine length body at 1-3\/4 inches overall increases rigidity over jobber-length bits\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and collets\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of +0.0000 to -0.0005 inches meets close-tolerance hole requirements\u003c\/li\u003e\n\u003cli\u003eMeets NAS 907 and ISO standards for quality-controlled applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style screw machine drill bit for use in standard drill chucks and collets compatible with straight-cylindrical shanks.

Secure the shank fully in the chuck or collet before operation and verify the spindle is at a complete stop before bit changes. Use appropriate cutting fluid or coolant for ferrous materials to extend tool life, noting this bit does not support through-coolant delivery. Follow applicable shop safety standards and machine manufacturer guidelines for speed and feed selection.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.0935 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Size\u003c\/strong\u003e: 42\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3\/4 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\u003eWeb Configuration\u003c\/strong\u003e: Parallel, Web-Thinned\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\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0005 inches\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 \/ ISO\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\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 48412\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51755167809842,"sku":"48412","price":71.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7630f6ba4a7cdd25c3156f51a7532c3b.jpg?v=1788951753","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-48412-screw-machine-drill-bit-0-0935-in","provider":"Voomi Supply","version":"1.0","type":"link"}
