It is manufactured from high speed steel (HSS) with an oxide coating that helps reduce friction and extend tool life under moderate cutting conditions. The bit features a 118-degree standard point angle, a web-thinned and tapered web configuration for easier starting, and a regular spiral flute pattern. At 4.875 inches overall length with a 3.5-inch flute length, it fits standard drill chucks and is suited for use in hand drills, drill presses, and magnetic-base drills. Machinists, fabricators, maintenance mechanics, and trade professionals who work with ferrous metals install and use this bit routinely.\u003c\/p\u003e\u003cp\u003eThis drill bit is appropriate for production and maintenance drilling in residential, commercial, and light industrial settings. Its straight cylindrical shank and letter S diameter of 0.348 inches make it a common choice when drilling clearance holes, tap-drill holes, or through-holes in steel plate, pipe, and cast iron components. The right-hand cutting direction is standard for conventional drill press and handheld power tool operation. It is sold individually and is well suited for shops that maintain a complete set of letter-size drill bits for close-tolerance work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLetter S diameter: 0.348 inches for close-tolerance hole sizing\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web-thinned, tapered web for reduced thrust on entry\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction withstands heat generated during drilling in ferrous metals\u003c\/li\u003e\n\u003cli\u003eOxide coating reduces friction and provides moderate corrosion resistance\u003c\/li\u003e\n\u003cli\u003eRegular spiral, 2-flute design promotes chip evacuation in steel and cast iron\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank compatible with standard drill chucks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber drill bit for use in standard drill presses, hand drills, and magnetic-base drills with chucks sized to accept a 0.348-inch straight shank.

The operator should clamp the workpiece firmly to prevent rotation. Cutting fluid or cutting oil is recommended when drilling steel to control heat buildup and extend bit life. Inspect the cutting edges before each use and replace the bit if chipping or dulling is observed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.3480 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point 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\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3480 inches\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel (HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.09 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: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 01189190\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51699945963826,"sku":"01189190","price":69.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/feda39140f36b44fa8bf1a886693d796.jpg?v=1788383887","url":"https:\/\/voomisupply.com\/products\/value-collection-01189190-letter-s-jobber-drill-bit-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
