Ground from high speed steel (HSS) with an oxide finish, the bit delivers reliable performance in production and maintenance drilling applications. The 118-degree standard point angle suits flat and round stock entry without requiring a pilot hole in most setups. At 1.2 mm in diameter (0.0472 inches decimal equivalent) with a 38 mm overall length, this is a small-diameter bit intended for precision hole work in tight tolerances, with a diameter tolerance held to -0.0005 to 0.0000 inches.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for metalworking trades, maintenance technicians, and machine shop environments where small-diameter holes are required in steel and cast iron workpieces. The 16 mm spiral flute length provides adequate chip evacuation for the short depths typical of jobber-length applications. The straight-cylindrical shank fits standard drill chucks without adapters, making it compatible with bench drill presses, hand drills, and CNC drilling setups that accept this shank diameter. It conforms to DIN 338, the international standard governing jobber-length twist drill geometry.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1.2 mm diameter (0.0472 inches) with diameter tolerance of -0.0005 to 0.0000 inches for consistent hole sizing\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with oxide coating for corrosion resistance and reduced friction\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned, tapered web for improved penetration and chip flow\u003c\/li\u003e\n  \u003cli\u003eRegular spiral, 2-flute design for efficient chip removal in steel and cast iron\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank (0.0472 inches) seats securely in standard drill chucks\u003c\/li\u003e\n  \u003cli\u003eManufactured to DIN 338 specification for consistent geometry and interchangeability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose jobber-length drill bit for use in cast iron and steel.

Use cutting fluid or a suitable metalworking lubricant when drilling steel to extend bit life and maintain tolerance. Verify chuck runout before use, as excessive runout will cause premature breakage on bits in this diameter range. Inspect the bit for chipping or dulling before each use; small-diameter HSS bits are susceptible to breakage if fed too aggressively.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1.2 mm (0.0472 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 38 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 16 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 22 mm (0.8662 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0472 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\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\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, 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\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Oxide\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\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0005 to 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 150\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 338\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose\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: 47227\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51728831775026,"sku":"47227","price":34.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1eca19afe150757905f09246344639f8_097c0a84-6bad-4363-914c-963444678758.jpg?v=1788696555","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-47227-jobber-drill-bit-1-2mm-hss-118-degree","provider":"Voomi Supply","version":"1.0","type":"link"}
