Built from coated high speed steel, it features a 135-degree split point that reduces walking and cuts required thrust compared to standard 118-degree geometry. The stub-length body — 1.75 inches overall with a 0.75-inch flute — sits closer to the chuck, minimizing deflection and improving hole location accuracy in short-reach applications. The straight cylindrical shank fits standard drill chucks without adapters. This bit carries NAS 907 designation and meets ISO standards, making it suitable for aerospace and precision manufacturing environments.\u003c\/p\u003e\n\u003cp\u003eThe 49415 is used in screw machine operations, CNC machining centers, drill presses, and hand-held drilling applications where a stub-length bit is preferred for rigidity. Its 0.082-inch diameter corresponds to Wire Size 45. Primary workpiece materials are cast iron and steel. The short overall length and parallel web configuration make it especially effective in gang-drilling fixtures and tight-clearance setups. It is sold individually with a minimum order quantity of 12 units per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point reduces thrust and eliminates center-punch requirement on most metals\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned parallel web lowers cutting resistance in cast iron and steel\u003c\/li\u003e\n  \u003cli\u003eCoated high speed steel construction extends tool life in high-cycle production environments\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length — 1.75 inches overall — maximizes rigidity and minimizes deflection\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute with 2-flute configuration for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance held to +0.0000 to -0.0005 inches for precise hole sizing\u003c\/li\u003e\n  \u003cli\u003eNAS 907 specification compliance; meets ISO standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard drill chucks accepting straight cylindrical shanks.

Secure the shank fully in the chuck and verify concentricity before cycling. Use appropriate cutting fluid or mist coolant when drilling steel to extend tool life, noting that this bit does not support coolant-through delivery. Inspect the split point for chipping or wear before each production run and replace when diameter falls outside tolerance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.082 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Size\u003c\/strong\u003e: 45\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.75 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\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\u003eWeb Configuration\u003c\/strong\u003e: Parallel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: 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\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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 -0.0005 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: 159\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: NAS 907\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO, NAS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0027 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: 49415\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51737478168882,"sku":"49415","price":34.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/69aafec5288a18f81d7bf6dd42623653.jpg?v=1788789045","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-49415-screw-machine-drill-bit-0-082-in","provider":"Voomi Supply","version":"1.0","type":"link"}
