Ground from high speed steel and finished with a titanium nitride (TiN) coating, it delivers extended cutting life compared to uncoated HSS bits. The 118-degree standard point angle suits a broad range of common workpiece materials. At 1.75 inches overall length with a 0.375-inch flute length, this is a compact bit sized for tight-clearance work or use in standard drill chucks and rotary tools. Licensed tradespeople and skilled shop technicians are the primary users.\u003c\/p\u003e\n\u003cp\u003eThe 70203 is suited for drilling cast iron and steel in residential and light commercial service work, fabrication shops, and mechanical rooms. The right-hand spiral flute geometry efficiently clears chips during through-hole and blind-hole operations. The straight-cylindrical shank, measuring 0.0469 inches in diameter, seats securely in standard keyless or keyed drill chucks. This bit conforms to DIN 338 dimensional standards, making it a consistent, predictable choice for repetitive drilling tasks across trade and industrial settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTitanium nitride (TiN) coating increases surface hardness and reduces friction for longer tool life\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle for general-purpose drilling in cast iron and steel\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web construction reduces thrust force at the cutting tip\u003c\/li\u003e\n  \u003cli\u003eRight-hand, regular spiral flute for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 338 for consistent dimensional tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose jobber-length drill bit compatible with standard keyed and keyless drill chucks accepting a 0.0469-inch straight-cylindrical shank.

Always wear appropriate eye protection when operating rotary cutting tools. Use cutting fluid or coolant when drilling steel to manage heat buildup and preserve coating integrity. Replace the bit if the cutting edge shows chipping or if the TiN coating is worn through at the tip, as a damaged edge increases thrust load and reduces hole quality.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 3\/64 inch (0.0469 inches)\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: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0469 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.0 inch (25.40 mm)\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: Regular Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eCoating\/Finish\u003c\/strong\u003e: Titanium Nitride (TiN)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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\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\u003eStandard\u003c\/strong\u003e: DIN 338\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 150T\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: 70203\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51748152639794,"sku":"70203","price":56.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/74869f25cdaf3b317ef81fb8306e4b98.jpg?v=1788889712","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-70203-jobber-drill-bit-3-64-in-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
