Built from high speed steel with a coated finish, this bit features a 130-degree faceted point angle and web-thinned, tapered web configuration that reduces thrust and improves chip evacuation at the start of the cut. At 0.1299 inches (3.30 mm) in diameter with an overall length of 50.00 mm, the stubby screw machine length profile provides added rigidity compared to jobber-length bits, making it well suited for precision drilling in tight setups and on machine tools. The straight-cylindrical shank measures 4.00 mm in diameter for secure chuck engagement.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for use in CNC machining centers, drill presses, and manual machine tools where short-length rigidity and accurate hole location are required. Primary workpiece materials include steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate. The 5xD flute-to-diameter ratio and two-flute spiral design support efficient chip removal across these materials. It is a single-unit item packaged individually and suited for tool crib stock or direct machine-side use.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eScrew machine length for increased rigidity over jobber-length equivalents\u003c\/li\u003e\n\u003cli\u003e130-degree faceted point angle reduces walking and improves positioning accuracy\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web lowers cutting thrust and entry force\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with coated finish for wear resistance\u003c\/li\u003e\n\u003cli\u003eTwo-flute spiral design promotes chip evacuation in steel and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with straight-cylindrical shank for standard chuck compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard drill chucks and collets accepting a 4.00 mm straight-cylindrical shank.

Ensure the machine spindle is fully stopped and the chuck is properly tightened before beginning any drilling operation. Use appropriate cutting fluid or coolant for the workpiece material to extend tool life, noting that this bit does not support coolant-through delivery. Follow applicable shop safety standards and machine manufacturer guidelines for speed and feed selection based on workpiece material and hole depth.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1299 inches (3.30 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 50.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 18.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 4.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Faceted\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, 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\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\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 to -0.018 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Aluminum, Aluminum Alloy, Aluminum Silicate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1100\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.016 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 61533\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51734923575602,"sku":"61533","price":34.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4fcf5df8412394c3e736c4e237cf2558.jpg?v=1788768191","url":"https:\/\/voomisupply.com\/products\/osg-61533-screw-machine-drill-bit-0-1299-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
