Built to DIN 338 standards, it features a 118-degree standard point angle with web-thinned, tapered web geometry for reduced thrust and easier starting. The 1.55 mm diameter corresponds to 0.0610 decimal inches, and the bit carries an oxide finish that provides mild corrosion resistance during storage and use. Two spiral flutes in a regular spiral configuration clear chips efficiently during right-hand cutting operations. Machinists, maintenance technicians, and fabricators working in trade shops and field environments will find this bit suitable for production and repair drilling tasks.\u003c\/p\u003e\n\u003cp\u003eThe 47234 is engineered for drilling cast iron and steel workpieces in general-purpose applications. The straight-cylindrical shank measures 0.0610 inches in diameter and seats securely in standard keyless or keyed drill chucks. With an overall length of 43.00 mm and a flute length of 20.00 mm, this bit fits compact drill presses and handheld power drills alike. The Series 150 designation places it within Chicago-Latrobe's standard general-purpose line, appropriate for shop, field service, and light production use where tight tolerances are not required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1.55 mm (0.0610 inch) diameter with a diameter tolerance of -0.0005 to 0.0000 inches for consistent hole sizing\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned, tapered web for reduced entry force\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability across cast iron and steel applications\u003c\/li\u003e\n  \u003cli\u003eOxide coating provides basic corrosion resistance and surface lubricity\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with regular spiral flutes for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eMeets DIN 338 specification for dimensional and performance standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose OEM-style jobber drill bit suitable for use in standard drill chucks accepting a 0.0610-inch straight-cylindrical shank.

Ensure the chuck is fully tightened and the workpiece is securely clamped before drilling. Use appropriate cutting fluid or coolant when drilling steel to extend bit life and maintain hole quality. Inspect the cutting edges before use and replace bits that show visible wear, chipping, or deformation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1.55 mm (0.0610 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 43.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 20.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 23.00 mm (0.9055 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0610 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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: -0.0005 to 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 338\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 150\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: 47234\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51747661381938,"sku":"47234","price":34.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1eca19afe150757905f09246344639f8_80d9daa1-281e-4367-9e4f-20d54285beac.jpg?v=1788884201","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-47234-jobber-drill-bit-1-55-mm-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
